1.2. Overview

WE500R is an easy-to-use remote monitoring and control system complete with an integrated web interface, where every single functionality of the system can be managed. The basic elements to start up the system are a variable, an event and an action. The first sections will therefore concentrate on the description of these elements and on the modbus protocol, the most used communication device protocol.

Further relevant concepts for a more comprehensive use of all available device functions are the data logging and the network configuration.

In the following sections all these concepts and their use through the WE500R will be described.

2.1. Generic variables

Many different types of variables are available, and for each of them parameters may differ. Only the section Generic Variable is valid for all types of variables. This section is structured as follows:

• Name: The name to be assigned to the variable. All alpha-numeric characters, and the character “_” are supported.
• Type: This allows to select the type of the variable. For each variable type the setting-parameters are different, see chapter 2.2. Type.
• Variable Status: enable/disable the variable
• Portal sending: it allows to enable/disable the sending of the variable value to an external portal/server. For further information regarding the data-sending, see relevant section 7. Data sending data sending.
• Non-volatile value: it allows to save the variable value every X minute and everytime the device is switched off or rebooted.
• Skip first read: enabling this optional function the system won’t read the first value of the variable. For example, if an event has been defined on the variable, and at the reboot of the system the variable is in alarm status, through this optional function no action will be enabled.
• Local log (min): it allows to set a different sampling time (in minutes) for each variable. The recorded data can be then exported or displayed in charts or tabs. For further information see section 8. Datalogger.

2.2. Type

Here are the different types of variables:

• Analog Input: Variables associated to the analogue inputs available on the WE500R. AI1 has to be selected to associate the variable with the analogue input 1 (connectors AN1 and GND) while AI2 has to be selected to associate the variable with the analogue input 2 (connectors AN 2 and GND). Further information on paragraph 2.3. Analog input variables (AI).
• Digital Input: Variables associated to the digital inputs available on the WE500R. It’s possible to choose among DI1, DI2, DI3, DI4, DI5 and DI6. Further information on paragraph 2.4. Digital input vriables (DI).
• Digital Output: Variables associated to the digital (relay) outputs available on the WE500R. Select DOUT1 for the digital output 1 (connectors RL1A and RL1B) or DOUT2 for the digital output 2 (connectors RL2A and RL2B). Further information on paragraph todo 2.5. Digital output variables (DO).
• Modbus: Variables associated to modbus registers. Further information on paragraph 3.2. Creation of Modbus variables.
• Virtual: these are virtual variables that can be created in order to manage alarms or elaborate formulas. Further information on paragraph 2.6. Virtual variables.

2.3. Analog input variables (AI)

In order to create a AI variable, i.e. associated to one of the analogue inputs available on WE500R, enter the page Administration → Variables. Clicking on New, it’s possible to enter the variable configuration page. Select Analogue Input on the field Type. Under the section Generic Variables all standard settings for any type of variable are available. For the description of all the fields of this section, see 2.1. Generic variables.

Let’s skip into the section Analogue Input: Variable Specific Settings.

First of all is requested to confirm the choice of the input, where to read the value. The choice is among AI1 or AI2. Then it has to be entered the measurement unit that will be displayed on charts and on Status -> Variable Status. Through the tabs Minimum value and Maximum value is possible to scale the variable. The minimum tension or current value will be associated to the Minimum Value; the same will be for setting the maximum value.

EXAMPLE: considering a temperature probe, controlled in tension, having min. value -20° and max. value 30°C, corresponding to 0V and 5V, it’s possible to configure the variable minimum value at -20, and the maximum at 30, in order to display the temperature directly expressed in degrees. Using the Decimals field, it will be possible to specify the number of decimals to be displayed.

WE500R analogue inputs have 10bit resolution and are hardware-configurable at factory (software configuration is not possible) in current (0-20mA), in tension (0-5V or 0-10V) and in temperature (NTC). The input value is constantly checked by the WE500R, thus keeping controlled any configured thresholds.

2.4. Digital input vriables (DI)

In order to create a DI Variable, i.e. associated to one of the digital inputs available on WE500R, enter the Administration → Variables page. Clicking on New, it’s possible to enter the variable configuration page.

Select Digital Input on the field Type. Under the section Generic Variables all standard settings for any type of variable are available For the description of all the fields of this section, see 2.1. Generic variables.

Let’s skip into the section Digital Input: Variable Specific Settings.

First of all is requested to confirm the digital input to be associated to the variable. It’s possible to choose among DI1, DI2, DI3, DI4, DI5 and DI6. Irrespective of the selected input, the fields Close label and Open label need to be completed. Close label refers to the value (or status), that will be displayed when the relevant digital input is closed, Open label refers to the open input. For WE500R a closed Digital Input variable has a logic value of 1. In case of an open input, the logic value is 0. This becomes a very important information for the definition and setting of the events.

Once filled in above mentioned fields, the operating mode has to be selected in the Input mode field choosing among the following options:

• Normal
• Counter
• Flow measurement
• Time counter

Depending on selection, the meaning of the following fields will change.

2.4.1. Normal

A DI → Normal type variable allows to display the status of the digital input. It is then possible to define events/actions connected to the status change (from open to closed and vice-versa).

The only additional field to be configured is the Inverted led. This can change the visualization of the variable on the page Status → Variables Status. If this option is disabled, the open status of the input will be associated to a grey spot, while the closed status to a green one. With enabled option, the situation will be the opposite. For further information see relevant section 6.1. Variables status.

2.4.2. Counter

A DI → Counter type variable allows to count impulses on a digital input.

The first field to be completed is Count start, i.e. the starting point of the counter. This value will be considered only the first time: if the counter should be reset, it would then restart from 0.

• Counter end refers the maximum limit to be reached for resetting the counter. If this field is configured at zero, the counter will increase indefinitely without reverting to zero.
• Count increment is the increment unit value of each impulse of the counter.
• Measurement unit is the unit of measurement assigned to the counter. This will be displayed on charts and on the page Status → Variable Status.

The last field to be configured is Edge trigger, i.e. the edge to be considered for the impulse. Selecting Falling edge the counter will increase when the input changes form closed to open; selecting Rising edge the counter will increase when the input changes from open to closed; selecting Rising and falling edge the counter will increase at every edge changing.

2.4.3. Flow measurement

A DI → Flow measurement type variable allows to calculate the flow rate.

In the Timeout field is entered the max. interval of time (expressed in seconds) between two impulses. Once the configured interval of time has passed, the variable will be reset to 0. This function can be useful in case, that the flow should stop for unexpected reasons. If no timeout value is set, the variable value would be the one of the last received impulse, and would therefore be giving wrong information at request and potentially generate incoherent logs.

In the Volume field is set the sample unit, to be associated with an impulse.

Measurement unit allows to set a unit of measurement for this variable, in Edge Trigger is possible to select the edge to be considered as an impulse: Falling edge if the changing from closed to open input has to be considered and Rising Edge for the contrary and Rising and falling edge for both of them.

EXAMPLE:

Assuming the following configuration with timeout at “600”(seconds), Rising edge, unit of measurement L/s (Liters per second) and volume at 100, the situation will be:

• The input changes from open to closed; WE500R starts counting
• The input changes from closed to open
• The input changes from open to closed after 20 seconds
• W500 calculates the sample volume (100) for the passed time (20 seconds) and displays therefore a result of 5L/s
• The input doesn’t change its status for at least 600 seconds
• WE500R reset the variable and waits for new incoming impulses before start counting again.

2.4.4. Time counter

A DI → Time counter type variable allows to count the opening/closing time of a contact (expressed in seconds). This variable can be used for calculating the total operating time of a defined machinery.

After the configuration of the Edge Trigger (reminding that Falling edge refers to the change from closed to open, Rising edge refers to the opposite and Rising and falling edge to both of them) the type of counter has to be selected among following possibilities:

• Permanent: After the start of the counter, WE500R will increase the value at every second, until the user will reset it
• Stop on opposite edge: the counting will start at the occurrence of an edge change according to the choice made on the relevant field; the counting will stop when reaching the opposite edge and restart again at next change.
• Reset on opposite edge: the counting will be reset when reaching the opposite edge, and restart from 0 when the selected edge will be reached again.

2.5. Digital output variables (DO)

In order to create a DO variable, i.e. associated to one of the digital outputs available on WE500R, enter the page Administration → Variables. Clicking on New, it’s possible to enter the variable configuration page.

Select Digital Output on the field Type.

Under the section Generic Variables all standard settings for any type of variable are available. For the description of all the fields of this section, see 2.1. Generic variables.

Let’s skip into the section Digital Output: Variable Specific Settings.

After the selection of the Output (between DOUT1 and DOUT2) to be associated to the variable to be created, it’s required to set the operating mode in the Output mode field. The available options are:

• Normally open: The output is normally open. Open label refers to the open status of the contact. Close label will close the contact.
• Normally closed: The output is normally closed. Open label refers to the open status of the contact. Close label will close the contact.
• Pulse open: The output operates in pulse mode. Open label refers to the open status of the contact. Close label will close the contact. Once closed, the outputs keeps this status for the time configured on the field Pulse duration, after that it returns automatically to the open status.
• Pulse closed: The output operates in pulse mode. Open label refers to the open status of the contact. Close label will close the contact. Once opened, the outputs keeps this status for the time configured on the field Pulse duration, after that it returns automatically to the closed status.

Regardless of the selected option, the field Status change delay(s) must be filled in with the number of seconds of delay required between an impulse and the enabling/disabling of the output.

Please note that the Non-volatile value option can be combined with the Output mode. If this option is not enabled, the start output status after a power-off or reboot will depend on the Output mode, i.e.: in case of Normally open/Pulse open output, the contact will start from open status; in case of Normally closed/Pulse closed output, the start of the contact will be from closed status. On the other hand if the non-volatile value option is enabled, the start output status will be the same as at the power-off or reboot of the system.

The status of the digital outputs can be modified through their association to an event either by an SMS command or directly from the page Status → Variables status.

2.6. Virtual variables

Virtual variables are not connected either to I/O or to modbus. These variables can be managed via SMS, EMAIL or from Status -> Variables status status, they can also be associated to an event or can be determined through a mathematical expression.

In order to create a Virtual variable enter the page Administration → Variables. Clicking on New, it’s possible to enter the variable configuration page.

Select Virtual on the field Type.

Under the section Generic Variables all standard settings for any type of variable are available For the description of all the fields of this section, see 2.1. Generic variables.

Let’s skip into the section Virtual Variable: Virtual variable: Variable Specific Settings.

Two types of virtual variables are available:

• Normal: Once set the unit of measurement on the field Measurement unit and the number of decimals on Decimals numbers, it’s possible to save the variable. Its value can be changed manually (via SMS, Email or from Status → Variables status) and/or automatically (as execute command on the page of events creation, see 4.2.3. Execute command).

• Math expression: Once entered the unit of measurement on Measurement unit and the number of decimals on Decimals numbers, its possible to define a mathematical expression to be applied to the variable.

A Virtual variable with Math expression allows to make calculations using variables or constants and to use some of the most common mathematical operations, as for example:

• Addition (+)
• Subtraction (-)
• Multiplication (*)
• Division (/)
• Exponentiation (^)
• Squared root (sqrt)
• Logarithm (log)
• Sine (sin)
• Cosine (cos)

or constants as:

• e(e)
• logarithm base 2 of e (log2e)
• logarithm base 10 of e (log10e)
• squared root of PI (2_sqrtpi)
• squared root of 2 (sqrt)
• squared root of 1/2 (sqrt1_2)

The use of round brackets is supported.

EXAMPLE 1:

“Var1” is the name of a variable of any type (not necessarily a Virtual variable) and its value is 10. In the field Math expression we could write:

Var1^2 In this case the Virtual variable would have a value of “100”.

EXAMPLE 2:

Var1 as above Var2 is another variable of any type and its value is 15 In the field Math expression we could write:

( Var1 * ( Var2 – 10 ) ) / 2

obtaining (10 * (15-10)) / 2 → (10*5)/2 → 50 / 2 → 25

The value displayed by WE500R will therefore be “25”.

Changing one of the expression’s factors, the result is automatically recalculated by the WE500R.

A Math expression Virtual variable can be used as a element inside another expression.

• Date/Time: This variable type will display seconds, minutes, hours, month’s day, month, year, day of the week, or day of the year.

Selecting for example Minutes [0-59] on the field Date/time, when it’s 12:35, the variable will show the value 35.

2.7. Bridge between variables

WE500R allows to create bridges between variables, in order to transfer the value or the status of a given variable to another variable. This type of function is very useful when it’s required to read via modbus the values of the variables associated to the I/O of WE500R.

Assuming for example, that it’s required to read the value of the analogue input “1” of the WE500R on any Master device, the following operations have to be executed:

• Create a 16 bit read-only modbus variable (3.2.3. 16-32 bit data type)
• Create an Analogue Input variable, associated, for instance, to the AI1 input (2.3. Analog input variables (AI))
• On the page where the Analog Input is created, click on the link Advanced.

• Click on the drop-down menu and select the previously created 16 bit modbus variable from the list.
• Associate the 16bit modbus variable to a modbus command and to a Slave network (3.1. Master/Slave Modbus)

Through this procedure two variables will have the same value. At every status/value change of the Analog Input variable will correspond a similar change of value of the modbus variable.

3.1. Master/Slave Modbus

WE500R allows to create an unlimited number of Modbus networks irrespective of the type (master/slave) or of the physical network (TCP/IP, 232, 485). This allows to have a system, where the WE500R acts as Master in some networks and as Slave in some others at the same time.

The separation between Master and Slave network is available only in the definition of the modbus network (Administration → Modbus → Networks)), while variables and commands can be defined on the same way. For example, a 16bit variable and its relevant reading command Read holding registers-0x03 can be created without specifying if they refer to a Master or a Slave network. Defining the network, two are the possible scenarios:

• Master: the WE500R will try to read the register associated to the variable, using the previously defined command.
• Slave: the WE500R will allow any Master device to read the register associated to the variable, using the previously defined command.

3.2. Creation of Modbus variables

To create a variable (of any type) enter Administration → Variables → Variables.

If some variables are already available, they will be displayed in the table with some of their main features.

To edit an existing variable click on its name, to create a new one click on New.

The name of the new variable is entered in the page for creating variables: the field Name accepts alpha-numeric characters and “_”. The space is not allowed.

Then select Modbus in the Type field.

Under the section Generic Variables all standard settings for any type of variables are available For the description of all the fields of this section, see 2.1. Generic variables.

According to the type of variable selected, the following section will have a specific structure:

• Modbus net: It allows to select a modbus network to be associated with the new variable to be created. If no modbus network is available, this field must be left blank.
• Modbus address: If the variable has to be associated to a Master network, this field must be completed with the slave address of the device to be interrogated by the WE500R. If the variable has to be associated to a Slave network, this field must be completed with a generic address, that the Master will interrogate to communicate with the WE500R.
• Memory address: this field must be completed with the memory register, to be associated with the variable.

It’s now necessary to select the Access mode, i.e. the type of modbus variable, among the following options:

• Read only: It’s possible to read the variable value but not to change it
• Write only: It’s possible to edit the variable value but not to read it.
• Read and write: The variable value can be read and edited.

In the field Data type is possible to select the variable number of bit.

3.2.1. 1Bit data type

In this field is requested to specify the position of the bit inside the word (1word=16 bit). Inside one single word there can be up to 16 variables of 1 bit each. If the variable, that we want to create, is on the first position of the word, the value “0” must be selected in the field Bit position. Alternatively if the variable, that we want to create, is on the last position of the word, the value “15” in the field Bit position must be entered.

In order to complete the creation of the variable, just set up a string for the open status (corresponding to value 0) and a string for the closed status (corresponding to value 1). These strings will allow to display the variable status (for example Open/closed, on/off, and so on..)

3.2.2. 8 bit data type

For the 8 bit variables is requested to specify the Bit position (it’s possible to choose only between 0 and 7, since 8 bit corresponds to half a word) and some other information available also for 16-32-32inv variables. If the variable, that we want to create, is in the first word position, the value “0” must be entered in the field Bit position. Alternatively if the variable, that we want to create, is in the middle of the word, the value “7” must be entered in field Bit position.

3.2.3. 16-32 bit data type

Selecting 16, 32 or 32inv on the field Data type, the following fields must be completed and specified:

• Measurement unit: measurement unit selected to be assigned to the variable
• Decimals number: quantity of decimal numbers to be displayed
• Minimum value: set the minimum (normally “0”) according to the type of variable
• Maximum value: set the maximum (for example 65535 for 16 bit variables) according to the type of variable.
• Scaled Minimum value/Scaled Maximum value: the two above mentioned fields are necessary for a correct interpretation of the read/written data by the WE500R, even though they might not be relevant for the end-user.

Selecting 16, 32 or 32inv on the field Data type, the following fields must be completed and specified:

• Measurement unit: measurement unit to be assigned to the variable
• Decimals number: quantity of decimal numbers to be displayed
• Minimum value: set the minimum (normally “0”) according to the type of variable
• Maximum value: set the maximum (for example 65535 for 16 bit variables) according to the type of variable.
• Scaled Minimum value/Scaled Maximum value: the two above mentioned fields are necessary for a correct interpretation of the read/written data by the WE500R, even though they might not be relevant for the end-user.

Assuming for example a 16 bit variable with min./max. values of respectively 0/65535: a user should need to measure a level from 0 to 10 meters. To this purpose it’s enough to set “0” as Scaled Minimum value and “10” as Scaled Maximum value.

3.2.4. 32 bit float data type

For the 32Float/32Float inv variables it’s necessary to set the measurement unit and the number of decimals. This type of variable doesn’t require any scaling.

By clicking Save the variable will be created.

Note

Information as Modbus address, Memory address, Access mode, Data type, Bit position are normally described in the data sheets of the modbus devices.

It’s important to make sure that all parameters are correct, in case of doubts contact the salve device’s manufacturer or the Support at Nethix.

For further information about the use of the Modbus Protocol, visit the official site modbus.org.

The following step is to create a modbus command, suitable to interact by reading or writing with the new created variable. In order to enter the section dedicated to the modbus commands, select Administration → Modbus → Commands on the menu.

3.3. Creation of Modbus commands

All modbus variables need to be associated to a read or write command.

Under the section Administration → Modbus → Commands all available commands (if previously created) will be displayed. In order to create a new command click on Add new command.

According to the type of created variable it’s possible to define a read/write command using one of the following functions:

• Read coils -0x01
• Read holding registers -0x03
• Read input registers -0x04
• Write single coil -0x05
• Write single register -0x06
• Write multiple registers -0x10

All functions available in WE500R respect the Modbus standard.

Once made the selection of the function to be used, the following parameters need to be set:

• Slave address: it’s the address of the slave device, where to send all requests/writings. This address must be the same as the one entered in the field Modbus address, previously set in the variable configuration.
• Memory address: it’s the memory address associated to the command. This must be the same as the one previously entered in the field Memory address of the variable.
• Words number: it’s the number of word where to use the command. Some functions allow to enter more than one word (to be checked on slave device’s documentation). Setting for example “1” as Memory address and “10” as Words number, it should be possible to use one single command to enter 10 consecutive registers.
• Interval: Interval of time for the reading function. For the write function this option is not available (the writing of a register is enabled at request). Setting for example “5”, the reading of one or more registers/word is executed every five seconds.
• Modbus Networks: If one or more Modbus networks have already been created, it’s possible to select the one to be associated with the created command.

Clicking on Save the command will be saved.

It’s important to make sure that all parameters are correct, in case of doubts contact the salve device’s manufacturer or the Support at Nethix.

For further information about the use of the Modbus Protocol, visit the official site modbus.org.

Once created the command, it’s possible to proceed with the definition of the modbus network. To enter this section, select Administration-> Modbus-> Networks from the menu, click the tab Networks on the top left side or click the link Create new network on the right side of the Save button.

In this last case, when the page for the creation of modbus networks opens, the new created command is already associated with the network.

3.4. Modbus network creation

All modbus variables and commands need to belong to a modbus network to grant a correct functioning. WE500R supports several modbus networks of different physical types.

Selecting Administration → Modbus → Networks from the menu, an overview of all available networks will be displayed.

It’s possible to create a new network clicking on Add new network.

Through the fields Peer type and Physical network type is possible to get 4 different combinations:

• Master-RTU
• Slave-RTU
• Master-TCP
• Slave-TCP

3.5. Istant reading

It’s possible to read or write one or more modbus registers without creating a variable or a command.

Entering the page Administration → Modbus → Raw, it’s possible to start an instant reading/writing of a given register, just by properly completing the following fields:

• Networks: Select a network among the available ones. This function is possible only if at least one network is already available.
• Function: Select the modbus function to be used in order to read or write the register/s.
• Words number: indicate the word number “1” in case of 1-8-16 bit variables, and the “2” in case of 32 bit or float variables.
• Slave address: indicate the slave address to be entered
• Memory address: indicate the memory address to be entered.

In the field Value it will be displayed the value read (in case of reading functions) and a notification message of successfully executed reading/writing will be sent by the WE500R.

3.6. Modbus expansions

WE500R includes 6 digital inputs, 2 analogue inputs and 2 digital outputs. The I/O module of WE500R can nevertheless be expanded with one or more additional expansion units of the range XP500.

In order to add or edit an expansion unit is necessary to enter the page Administration → Modbus → Expansions and click on New or select one of the previously added expansions.

• Name: Enter the name to be assigned to the expansion. This name will be used to create a variables group, where the variables referred to the inputs/outputs of the expansion unit will be saved.
• Type: It’s possible to select the type of expansion unit to be added.
• Client address: In this field is selected the slave address to be assigned to the expansion.

After clicked on Save, the WE500R will try to set the client address entered in the connected expansion unit, using the default communication parameters (38400, 8, N,1) and assuming that the expansion is connected to the slave address 1 (according to manufacturing settings). It’s therefore recommended, always to keep the slave address 1 free.

Once added the expansion, the WE500R will automatically create all variables and modbus commands (beside the network, if not already available) in order to allow the communication with the XP500. The variables name can be then later on modified from Variables.

3.7 Manage Modbus errors

WE500R allows to manage the modbus errors on the page Administration → Modbus → Errors handling, clicking on new.

At the occurence of a modbus error it’s possible to set a variable at a specific value:

• Network: the network where the error occurs
• Slave ID (address): the slave address to be monitored ( this field appears only in case of master networks)
• Timeout (seconds): the error is displayed only if available for more than X seconds
• Variable: the variable to be set. Selecting None, it’s possible to avoid the setting of any variable
• Value: the value, that the variable should assume at the occurence of the error

Clicking on Save the error handling is configured and starts monitoring the errors that may occur on the selected network.

4.1. Events

The events allow the WE500R to acknowledge when a monitored parameter reaches a relevant threshold for the user.

Different types of events are available and each type of event is composed of several parameters, in order to reach a high flexibility in controlling and monitoring the system.

To create an event, enter the page Administration/Events/Actions and click on New.

The tab Delete allows to cancel one or more selected events. With the tab Update it’s possible to edit the enabling/disabling of one or more events, to configure events as alarms and send them to a web portal. For a quick search by name of one or more events the Tab Find can be used.

All occurred events can be displayed in a chronological chart, entering the page Status → Logger status → Events.

From this page it’s possible to display one or more events, by selecting them, and the time interval to be considered, from the relevant list, and possibly export data on CSV or Excel format.

During the creation of an event, and after entering the name, must be selected the type of event among Variable, Events, Formula, Incoming data or Scheduler (see 5. Scheduler).

Some generic options can be activated according to the selected type of event: it’s possible to decide the enabling of the event from Status, the visualization as an alarm on the field Set as alarm and to send it to a web portal from the field Send to portal.

4.1.1. Event on variable

First of all a variable in the field variable has to be selected.

In the drop-down menu is possible to see all previously created variables and select the one to be associated to an event.

The second parameter to be selected is the Condition, among the following possibilities: EQUAL, NOT EQUAL, GREATER THAN, GREATER OR EQUAL THAN, LESS THAN and LESS OR EQUAL THAN.

It’s now necessary to set the threshold value for the event triggering, i.e. a numeric value will be entered in the field Value, according to the type of the selected variable.

It’s possible to set a value in the field Delay. The value is expressed in second, the function of this parameter is to postpone the triggering of the event for a defined time.

Finally it’s also possible to enable the field Skip first event, that allows the WE500 to ignore the first time that an event occurs.

This can be useful, for instance, in case of an analogue variable (with an ever changing value, having a floating mode). Setting a delay it’s possible to avoid the triggering of any event, before the value has come to a stabilized value. If the delay has been for example set at 10 seconds, the value entered in the relevant field will be kept until the expiry of the 10 seconds, allowing the execution of any possible events.

Once set all parameters, the situation may be the following:

Variable: Var1

Condition: EQUAL

Value: 3

Delay:10

According to this configuration the event would be triggered 10 seconds after the variable Var1 has reached the value 3.

4.1.2. Event on event

EXAMPLE:

Selecting Events on the field Type, is possible to decide whether to enable or not the event from Status and to display it or not as an alarm in the field Set as alarm.

If this last option is enabled, at the occurrence of the event, a red ”X” will be displayed near the name of the relevant variable on the page Administration->Variables status, to indicate the presence of a critical condition.

The field Condition allows to select the type of comparison that has to be made between one or more events. The two available conditions are AND or OR.

In the fields Events 1…5 is possible to select two or more events among those previously created.

Back to the above mentioned example, and assuming that the selected condition is AND, the event on event “EV3” would be triggered when “Var1” is equal to “3” (of course considering the set delay) and when “Var2” is equal to “5”.

On the other hand, if the selected condition is OR, “EV3” would be triggered even if only one among “EV1” and “EV2” should occur.

All events may be used to generate an event on event.

4.1.3. Event on formula

Event on formula is an event that will occur comparing two maths expressions.

Selecting Formula on the field Type, it’s possible to decide whether to enable or not the event from Status and display it or not as an alarm in the field Set as alarm.

If this last option is enabled, at the occurrence of the event, a red ”X” will be displayed near the name of the relevant variable on the page Administration->Variables status, to indicate the presence of a critical condition.

In the fields Formula can be entered a real maths formula, that may include several arithmetical operations, constants or variables.

The available operations are:

• Addition (+)
• Subtraction (-)
• Multiplication (*)
• Division (/)
• Exponentiation (^)
• Squared root (sqrt)
• Logarithm (log)
• Sine (sin)
• Cosine (cos)

and constants as:

• e(e)
• logarithm base 2 of e (log2e)
• logarithm base 10 of e (log10e)
• square rooted of pi (2_sqrtpi)
• square rooted of 2 (sqrt)
• square rooted of 1/2 (sqrt1_2)

The use of round brackets is also supported.

Beside the formula to be compared, it’s also necessary to select a Condition among the following: EQUAL, NOT EQUAL, GREATER THAN, EQUAL OR GREATER THAN, LESS THAN, LESS OR EQUAL THAN.

It’s possible to set a value in the field Delay. The value is expressed in second, the function of this parameter is to postpone the triggering of the event for a defined time.

Finally it’s also possible to enable the field Skip first event, that allows the WE500 to ignore the first time that an event occurs.

Here is an example of event on formula:

Formula: (Var1+5)/2 Condition: EQUAL Formula: Var2 Delay: 10

The event will be triggered when the result of the formula “(Var1+5)/2” will remain equal to the value of “Var2” for at least 10 seconds.

4.1.4. Incoming data

• SMS
• Email
• Ring

Selecting SMS or Email on the field Data source, it’s possible to enter any text in Message and enable one or more users/groups from the filed Users.

Thus the event will occur when the WE500R receives an SMS or an Email, containing the specified text, sent by an authorized user in Administration –> Users.

Note that the WE500R checks only the object of the mail (relevant commands or instructions must therefore entered in the object and not in the body of the email).

Selecting Ring on Data source there will be the possibility of choosing one or more of the registered users.

The event will occur, when the WE500R receives a ring from one of the authorized users. At ring receipt, the WE500R will disconnect the call, avoiding any costs.

It’s recommended to disable all mailbox or call waiting functions of the SIM installed in the device. For each user is possible to define only a single Ring event.

4.2.1. Send Email

Selecting Send Email, it’s allowed to enter the text to be sent at the occurrence of the event.

If previously used messages are available it’s possible to select them from the field Message, using the drop-down menu.

For entering a new text, select Create new message.

To modify an already existing text, enter the messages page using the link on top of the page or the link in the left side menù Administration –> Events/Actions –> Messages and select the message to be modified.

Once the message is defined, it’s possible to select the receivers among the several available users and groups.

After definition of the event and action that generate the email to be sent to a defined user, some more conditions are necessary:

• Availability of a LAN or GPRS/HSPA connection (see section 10.1. Connectivity and 12.3. Ping)
• The configured user/s should be enabled to receive notifications emails at a valid email address ( see 9. Users)
• The mail service must be properly configured (see 10.1.7. Email)

All the text used for the existing actions are available on the page Administration/Event/Actions/Messages. From this page is possible to cancel any message, by clicking on the relevant tab and then Delete, or edit one or more messages by clicking upon it.

On the messages to be sent at the occurrence of defined events, it’s possible to write the value of one or more variables: it’s enough to report on the text of the message $ and the name of the variable.

EXAMPLE

If a variable “VAR1” has value 5.7, and this should be reported in the alarm message, the text of the message should be the following:

Alarm high level. The level is $Var1 meters

The message that will be sent to the configured users will then be:

Alarm high level. The level is 5.7 meters

Inside one single message more variables can be reported.

4.2.2. Send SMS

Selecting Send SMS it’s possible to enter the text to be sent at the occurrence of a defined event.

If previously used messages are available it’s possible to select them from the field Message, using the drop-down menu.

For entering a new text, select Create new message.

To modify an already existing text, enter the messages page using the link on top of the page or the link in the left side menù Administration –> Events/Actions –> Messages and select the message to be modified.

Once the message is defined, it’s possible to select the receivers among the several available users and groups.

After definition of the event and action that generate the SMS to be sent to a defined user, some more conditions are necessary:

Network Availability The configured user/s should be enabled to receive SMS at a valid telephone number ( see section 9.1. How to create a new user) The SMS service must be properly configured (see section 10.1.5. SMS)

All the text used for the existing actions are available on the page Administration/Event/Actions/Messages. From this page is possible to cancel any messages, by clicking on Delete, or edit one or more messages by clicking upon it.

On the messages to be sent at the occurrence of defined events, it’s possible to write the value of one or more variables: it’s enough to report on the text of the message $ and the name of the variable.

EXAMPLE:

If a variable “VAR1” has value 5.7, and this should be reported in the alarm message, the text of the message should be the following:

Alarm high level. The level is $Var1 meters

The message that will be sent to the configured users will then be:

Alarm high level. The level is 5.7 meters

Inside one single message more variables can be reported.

4.2.3. Execute command

Selecting Execute a Command in the field Type is possible to choose a variable among those available in the list below and then specify a value in the filed To.

Thus, at the occurrence of the defined event, the selected variable will be set at the value entered in the field To.

The drop-down menu could miss some of the already created variables. The reason is that the system automatically recognizes the variables, where the value can be modified:

• DO Varaiables
• Virtual variables
• Modbus write variables
• Modbus write/read variables

For the same reason the following variables will never be included in the menu: * DI variables * AI variables * Modbus read variables

Through an action of Execute a Command, it’s possible to create some automatic operations at the occurrence of a certain event, as for example to close the contact of an output if an analogue input reaches a defined threshold.

4.2.4. Ring a user action

Selecting Ring a user in the field Type it’s possible to choose one or more users/groups of users, that WE500R will send a voice call in case the associated event occurs.

If no feedback will be received, the WE500R will stop the call automatically after 30seconds, and then pass to the following user/s in the list.

If the user rejects the call, the WE500R will immediately pass to the following user. Likewise, if a user should answer, the WE500R will pass to the following user in the list immediately after the termination of the call.

4.2.5. Reboot action

Selecting Reboot in the field Type, it’s possible to reboot the WE500R at the occurrence of the associated event.

4.2.6. Power off action

Selecting Poweroff in the field Type, the WE500R can be turned off at the occurrence of the associated event

A typical situation where the controlled power-off of the device can be useful, is when the WE500R is battery powered ( for example using a UPS500).

When the battery is low, this could send a request of controlled power-off to the WE500R (through a digital/analogue input), in order to avoid unexpected current interruptions while the system is working.

6.2.1. Set

The variables that can be modified in their value through the SET command are the following: counters on digital inputs, digital outputs, modbus write variables ( and read/write) and virtual variables.

The SET command can be used both through SMS and Email. In both cases it’s necessary to define the parameters of the users, authorized to send commands to a WE500R (telephone number for the SMS, email address for the email). For authorizing the users to send command, it’s necessary to enable the relevant functions on the user configuration page. Also the SMS and/or the Email service (in this last case the incoming email service will be enough) must be enabled.

Once appropriately configured the WE500R, it’s possible to use the following syntax:

Set Variable Name=Value

Assuming for example,that the virtual variable “Var1” has to be set with value “5”, the SMS to be sent will be the following:

Set Var1=5

If the command will be sent by Email, the same syntax, as in the above example, has to be reported on the Email’s object. If more than one variables value have to be set, it’s enough to separate each command with a space:

Set Var1=5 Var2=10 Var3=15

When writing the commands it’s important to respect the correct spelling of the variables name.

6.2.2. Get

All variables can be read, with the only exception of the modbus write-only variables.

The GET command can be used both through SMS and Email. In both cases it’s necessary to define the parameters of the users, authorized to send commands to a WE500R (telephone number for the SMS, email address for the email). For authorizing the users to send commands, it’s necessary to enable the relevant functions on the user configuration page. Also the SMS and/or the Email service (both incoming and outgoing) must be enabled.

Once appropriately configured the WE500R, it’s possible to use the following syntax:

Get Variable Name Value

Assuming for example, that the value of the virtual variable “Var1” has to be interrogated, the SMS to be sent will be the following:

Get Var1

If the command will be executed by Email, the same syntax, as in the above example, has to be reported on the Email’s object. If more than one variables value have to be interrogated, it’s enough to separate each command with a space:

Get Var1 Var2 Var3

When writing the commands it’s important to respect the correct spelling of the variables name.

7.2.1. Server

From the Tab Server is possible to activate the data sending to the Nethix Portal or to any other remote server.

Selecting Nethix API from the Protocol field and flagging Enable, the data sending to the portal nethix.co will be activated.

The portal service offered by Nethix allows:

• To send data and to display an overview of all installed devices
• To display the detailed data of every single device and all the records of the sent data in a chart or tab
• To create a synoptic that displays in a simpler and more intuitive way the status of the device.
• To allow a remote access from the device to the portal, in order to read/write the variables value, even if a public IP is not available.
• To establish a VPN connection between a PC and a portal. Activating the remote access, it will be possible to create a private VPN with all the owned devices, avoiding all possible difficulties referred to the non accessible IP addresses.

For further information, contact Nethix Support.

Default Settings are:

• Server address: https://nethix.co
• Server port: 443

The updated parameters will be indicated by Nethix when the service will be activated.

In alternative it’s possible to enable the data sending to an external server. For this it’s enough to choose the option HTTP on the field Protocol.

In the General Setup the following parameters must be defined:

• Enable: enable/disable the sending
• User agent: it’s the user agent that WE500R will use for authenticating in the server
• Device ID: ID of the device (this can be used for managing more than one device inside the same server)
• Server address: server address (complete with http://) where to send the data
• Server port: Port of the server
• Send mode: mode of the sending. It’s possible to choose among POST and GET. Before activating the option, please ask Nethix Support to have an example string sent by WE500R.

In Data Delivery is possible to define the path inside the server, where the processing script of the received data is available

• Script address: name and complete path of the script inside the remote server
• Manage portal response: WE500R waits for the commands of the server every time it has to execute a data sending

In IP Delivery it’s possible to specify the path, where to find the script , that will manage the sending of the IP address by the WE500R. It’s enough to fill in the field Script Address.

7.2.2. FTP

From the tab FTP it’s possible to configure the sending of the logged data to any FTP server:

• Enable: enable/disable the sending
• Server host name: Server Port (default 21)
• Username: name of the user for authenticating on the server (if necessary)
• Password: password for authenticating on the server (if necessary)
• Destination folder: Server folder where to send the data (complete path).
• Delivery time: defined the interval of time for sending the data to server. Delivery and sampling time (field Sampling frequency on tab General) can be different. For example it will be possible to sample a variable every minute and to send data once in a day.

7.2.3. Dropbox

• Enable: enable/disable the sending
• Authorization: in this field is reported the access code of the Dropbox-account to be used. In order to get this access code, it’s possible to click on the nearby link and then be redirected to the Dropbox site. After login and confirm, the access code will be displayed and can be copied.
• Delivery time: Specify the frequency of data sending to cloud. Delivery and sampling time (field Sampling frequency on tab General) and can be different. For example it is possible to sample a variable every minute and to send data once in a day.

7.2.4. Email report

From the tab Email report it’s possible to configure the sending, of the data collected by WE500R, to one or more email address.

• Enable: Enable/disable the sending
• Delivery time: Defines the frequency of the data sending. Delivery and sampling time (field Sampling frequency on tab General) can be different. For example it is possible to sample a variable every minute and to send data once in a day.

For a correct sending of the report, the E-mail account associated to the WE500R, 10.1.7. Email), should be properly configured and the option Receive report by email should be enabled in a proper configuration of the users (9. Users).

10.1.1. LAN connection

On the page Administration → Networking → LAN it’s possible to modify all parameters of the RJ45 Interface.

First of all the MAC address of the device will be displayed, with the option of using the LAN network on static IP address or on DHCP.

If the Static address will be selected, the following parameters must be set for the correct operation of the service:

• IP address static IP address assigned to the WE500R. Make sure that the address is available and not used on other devices.
• Netmask Subnet mask. A valid netmask must be entered, according to the specifications of the own local LAN.
• Gateway Network gateway
• DNS DNS that can be assigned to the WE500R ( max. 3)

After settings modification the WE500R requires a reboot in order to activate them. If the entered parameters are correct, it’s possible to enter the web interface of the WE500R (even remotely if the network allows it), to send emails and send data to a Portal/Server.

For further information regarding the status of the LAN connection, see page Diagnostics → Networking on section LAN Interface ( see 12. Diagnostic)

10.1.2. WLAN connection

First of all it will be displayed the MAC address of the Wi-Fi device connected to the WE500R, and it will be given the possibility to choose between a static or dynamic Ip address.

Choosing the static IP address, all necessary parameters for a proper functioning of the service will be required.

• Choosing a static ip-address the following parameters must be set for a proper operation of the service:
• IP address: static IP address assigned to the WE500R. Make sure that the address is available and not used on other devices.
• Netmask: Subnet mask. A valid netmask must be entered, according to the specifications of the own local LAN.
• Gateway: Network gateway

Then the access data of the wi-fi network, where the WE500R has to get connected to, have to be defined:

• SSID: Complete name of the wi-fi network
• Protection: Encryption of the access key
• Key: type of key/password for the authentication

After clicking on Save, the We500 starts to scan the on-site available Wi-Fi networks. Once found the network with the previously set SSID, the WE500R will make the authentication using the indicated parameters.

If all operations will be successful executed, the indicators on the status panel will become green.

The WLAN network allows all operations permitted by the LAN network (remote access to the web server, data sending, email sending)

For further information regarding the status of the LAN connection, it’s possible to enter the page Administration → Diagnostics → Networking on section WLAN Interface (see 12. Diagnostic).

10.1.3. SIM parameters

Beside the parameters related to the connectivity, for the correct operating of the SMS and RING services, it could be necessary to define some SIM’s parameters according to the selected provider.

Those parameters are available on page Administration → Networking → SIMs.

• APN: It’s the name of the access point of the GPRS/HSPA network. It changes according to the provider and to the contract with it (in some cases this may be not necessary). It’s an important parameter for a proper functioning of the connection. In case this should not be known, please contact the provider or Nethix Support.
• Username: it’s the username for the GPRS/HSPA connection. This field is normally blank, if it’s not differently required by the provider.
• Password: Password to be used for the GPRS/HSPA connection. This field is normally blank, if it’s not differently required by the provider.
• SIM number: It’s the Telephone number of the SIM inserted in the WE500R. This is not relevant for the functioning (this number is never used by the WE500R), but can be used for identifying the device later on.
• SMS center: It’s the SMS Service Centre of the Provider. With some types of SIM this could not be required. If this number is not known, please contact the Provider or Nethix Support.

WE500R includes two completely independent communication channels on mobile networks GSM/GPRS/UMTS/HSPA, that allow the parallel interaction with two different carriers.

The redundancy is provided through three different policies that can be selected according to the users needs:

• Switch on error Modem A is always working, but if a connectivity issue arises, such as continuos data connection failures or modem malfunctioning, it switches to modem B and remains on this modem until a new issue arises causing a switch back to modem A. This is the default policy.
• Time sharing between SIMs Each modem works for a given period of time. When that period timeouts, it switches to the other modem. The timeouts of each modem can be different. This policy could be useful when the users wants to consume the SIMs credit evenly. If modem A is currently working and presents an issue such as continuos data connection failures or modem malfunctioning, it switches to modem B and remains on this modem until its period times out. At that moment, it switches back to modem A.
• Priority to SIM A/Priority to SIM A One of the two modems, eg. modem A, is always working. If a connectivity issue arises, such as continuos data connection failures or modem malfunctioning, it switches to modem B, but it keeps monitoring modem A until it recovers. At that point it switches back to modem A and remains on it.

10.1.4. GPRS/HSPA connection

WE500R allows to establish a GPRS/HSPA connection in order to enter the web interface of the device and send data or emails, even if no Ethernet or Wi-Fi connections are available.

In order to activate the connection enter the page Administration → Networking → GPRS/HSPA.

Once enabled the service with a flag on the field Enable, it’s required to specify whether the connection must be always on or on demand.

• Always on: The WE500R will keep the connection always on. In case it should be interrupted (missing credit, Signal not available..) the connection will be restored as soon as possible.
• On demand: the connection is activated on request by an authorized user through a wake-up message (11. Commands) and after 15 minutes is automatically disabled. If the activated services require a connection for data sending or email sending.., the connection of the WE500R will automatically be closed at the end of the configured operations.

If the parameters have been properly configured, after a few minutes the GPRS/HSPA connection will be activated. On the status panel, positioned on the right side of the web interface, the GPRS/HSPA indicator will become green and beneath it the connection uptime and the relevant IP address will be displayed.

The WE500R offers also the possibility of associating the connection with a dynamic DNS service, choosing from the List of Providers available on section Dynamic DNS. This service allows to access the WE500R even if no static IP is available, since the device will be identified by the selected provider at every single connection, allowing the users to reach the web interface, just entering the hostname as configured on the browser. For further information see the Provider’s site or contact Nethix Support.

Make sure that the GPRS/HSPA connection has been successfully established, by checking if all necessary operations have been executed:

• Provide the WE500R with an enabled data SIM card (rechargeable or with flat tariff contract)
• Enter the APN (10.1.3. SIM parameters) for the Providers, that require it.
• Connect the antenna and check the strength of the available GSM signal.
• Enable the GPRS/HSPA service.

It’s possible to check the quality of the connection by using the diagnostic tool Ping (12.3. Ping). Further information regarding the status of the connection can be found on page Administration → Diagnostics → Networking (12.2. Information of connectivity)

10.1.5. SMS

To enable/disable the SMS service go to page Administration → Networking → SMS. Beside the flag for enabling the service, it’s possible to enable or disable the sending of pre-set SMS notifications (4. Events/Actions).

Enabling the service, it should be necessary to enter the SMS Service Centre number (10.1.3. SIM parameters).

Once enabled the SMS service, it’s possible to test the functioning through the section SMS test: entering a valid telephone number, complete with country code (for example +39NNNNNNNNNN for Italy), the WE500R will try to send an SMS with the following text ” Test message from WE500R “.

For granting the proper functioning of the SMS service, allowing the users to communicate with the WE500R and the WE500R to send alarm notifications, the procedure below must be carefully carried out:

• Enter the SMS Service Centre (10.1.3. SIM parameters).
• Enable the SMS service as described before
• Enable the SMS sending on event (field Send events on Administration → Networking → SMS)
• Define at least one user with activated SMS sending/receiving functions (9. Users)
• Create one or more events as Send SMS action (se 4. Events/Actions).
• Make sure that the SIM is properly inserted and with enough credit.
• Make sure that the antenna is properly connected and that the available signal is strong enough.

All sent and received SMS can be displayed on page Status → Services → SMS: the first page to be entered will show the SMS received by the device.

In the table the following information will be available:

• Number: shows the Phone number of the SMS sender
• Reception date: displays the date and time when the WE500R has received the message
• Text: contains the text of the received message

The button Refresh can be clicked at any time in order to update all information; Empty box for deleting all messages stored on Inbox.

Clicking on the drop-down menu on the top of the table, it’s possible to pass from Inbox to Outbox.

On this table is possible to display all the messages not yet delivered by the WE500R. The available information are the following:

• Number: refers to the phone number of the message receiver
• Creation date: shows the date and time when the message has been created
• Text: displays the text of the message

The button Refresh can be clicked at any time in order to update all information; Empty box for deleting all messages available on Outbox (such messages won’t be delivered).

Clicking on the drop-down menu on the top of the table, it’s possible to pass from Outbox to Sent.

On this table are displayed some information regarding the SMS already delivered by the WE500R:

• Number: shows the receiver of the delivered messages
• Send date: displays the date and time when the We500 has delivered the message
• Text: contains the text of the sent messages

The button Refresh can be clicked at any time in order to update all information; Empty box for deleting all messages stored on Sent.

10.1.6. Ring

One of the actions that can be associated to an event (incoming or outgoing) is the RING, that can be sent or received to/by one or more registered users (4. Events/Actions).

To enable the Ring Function go to page Administration → Networking → Ring and enable the field Enable rings.

Once enabled the function and clicked on Save, it’s possible to use this option.

To make sure that this function is properly operating, it’s recommended to check the following points:

• Enable the Ring function, as described above.
• Define at least one user with valid telephone number, enabled to receive/send rings (see 9. Users)
• Make sure that the SIM card is properly inserted and voice call enabled.
• Make sure that the SIM card has enough credit to send rings.
• Make sure that the GSM antenna is properly assembled and that the signal is strong enough

10.1.7. Email

Before proceeding with the configuration of the WE500R, it’s necessary to make the following:

• After the selection of the provider (Gmail, Yahoo, Hotmail etc..) enter the provider’s site and create a new valid mail account
• In the site of the provider, collect all information regarding the parameters to be entered in order to configure the mail service

Once a new account has been created, it’s possible to proceed with the configuration of the WE500R, enabling the outgoing emails, the incoming emails or both of them from the page Administration → Networking → Email.

On the section Outgoing mail setup the parameters required for the email sending from the WE500R must be set:

• Enable outgoing mail service it enables/disables the email sending service.
• Server type it allows to choose the type of mail server (at the moment only SMTP available)
• Server address it’s the address of the mail server ( for example smtp.gmail.com)
• Port it’s the number of the access port (for example 587)
• Email address the email address associated to the WE500R. This will be the address visualized by the receivers of the emails.
• Username It’s the username of the mail account associated to the WE500R.
• Password It’s the password of the mail account associated to the WE500R.
• SSL-TLS Encryption

Once clicked on the button Save, a new section, called Outgoing mail test, will appear on the bottom of the page: from this section it’s possible to send a test email to any address.

A properly configured mail service allows the WE500R to send notification mails to the configured users (see 4.2.1. Send Email)or to send scheduled reports (see 7.2.4. Email report).

On the section Incoming mail setup the parameters required for the email sending from the WE500R must be set:

• Enable incoming mail service: Enables/disables the email receiving service.
• Server Type: Type of mail server (at the moment only POP available)
• Server address: the address of the mail server (for example pop.gmail.com)

At any time it’s possible to click on the button Refresh in order to update the information, or Empty box, in order to delete all messages available inside Sent.

10.1.8. VPN

From the page Administration → Networking → VPN it’s possible to enable the VPN service to Nethix Portal or to a corporate VPN server.

It’s possible to enable the VPN according to two modes:

• automatic
• manual

The automatic VPN is used to build up a secure connection to Nethix Portal. The automatic VPN allows also to build up a secure and encripted connection between a PC and the device.

For further information about the use and the advantages granted by the VPN service, see the relevant manual manual.

On the other hand the manual VPN is used to build up a secure connection to a external VPN service, compatible with OpenVPN clients.

The parameters to be configured in order to enable a manual VPN are the following:

• VPN mode: modality of the VPN, in this case: Manual
• VPN configuration: this is the configuration file, released by the selected VPN Service Provider
• VPN Service user: the username for authenticating on the VPN service
• VPN Service password: the password for authenticating on the VPN service

10.1.9 NAT

From the page Administration-> Networking->NAT it’s possible to enable the NAT function and set the rules for the port forwarding.

Enabling the function NAT, the device will run in gateway mode, i.e. it will provide connectivity through the interface, selected by the connected devices.

Setting the routing rules it’s possible to forward to a defined IP address and port, the traffic coming to the WE500R.

For instance:

WE500R is inside a LAN network and has the local IP address 10.0.0.1 and the public IP address 1.2.3.4 (for entering internet). It is necessary to reach the port 80 of another device (connected with WE500R) having local IP address 10.0.0.2. It’s possible to set the following rule:

• Source port: 8080
• Destination IP: 10.0.0.2
• Destination port: 80

According to this rule, by typing 1.2.3.4:8080 in the address bar of your internet browser, you will be redirected to the port 80 of the device having IP 10.0.0.2.

10.2.1. Information about the system

On the page Administration → General Setup → System, under the section System, it’s possible to configure the contents to be displayed on the page Status → Site immediately after the login. These parameters are not compulsory and are used just to identify the device.

• Site name: the name assigned to the device
• Site id: numeric ID assigned to the device
• Country: Country where the device is installed
• Region: Region/Area where the device is installed
• Picture: when this option is enabled, it’s possible to select an image, by clicking on Select file, and then display the selected image after the login (for example the picture of the installation, of the company..and so on..). The picture will be displayed on the page Status -> Site.

10.2.2. Date and time

On the page Administration → General Setup → System**under the section **Time/Date, it’s possible to set the date and time of the device:

• Installation time/date: It states the date and time, when the device has been installed. This information has no influence on the functioning and has the only reason of identifying the installation.
• Set time/date: It allows to set the date and time of the device.
• Enable NTP: it enables the automatic synchronization of time. Once per day and at every reboot, the WE500R will connect to the server in order to update date and time precisely, according to the relevant timezone.
• Select time-zone: it allows to set the timezone of the device.

It is also possible to specify a custom NTP server, by clicking the Advanced link.

10.2.3. Web-cam

It’s possible to enable a web-cam to be associated to the device, in order to display the captured image after the login. The image will be refreshed according to the pre-set timing. The webcam doesn’t have to be necessarily connected to the WE500R via Ethernet, but it must be available via LAN, Wi-Fi, GPRS or HSPA.

In order to define the web-cam parameters, go to page Administration → General Setup → Site Configuration, on the section Web-cam:

• Webcam: it enables the function
• Image URL: it refers to the network path for the WE500R to be connected to and receive the web-cam images.
• Refresh: Image refresh time expressed in seconds. The refresh time depends also by other factors, as for example the speed and the quality/resolution of the connection.
• Timestamp: enabling this function, the date and time of the image acquisition will be shown.

10.2.4. GPS

The WE500R allows to get or to set the geographical coordinates, in order to show through Google Maps the precise location of the installed device. For activating the GPS function, go to page Administration → General Setup → Site Configuration on section GPS service.

When the function has been activated, it’s possible to decide how to use it, selecting on the field Coordinates type between the two options Manual and GPS.

• Manual: it allows to set manually the device coordinates. The fields Latitude and Longitude will be filled in with the coordinates acquired from Google Maps.
• GPS: it allows to acquire the geographical coordinates directly from a GPS sensor, connected through the serial 232 of the WE500R. The GPS sensor must be requested at order confirmation, since it’s considered as an optional accessory.

After a proper configuration of the required parameters, irrespective of the selected mode, it’s possible to display the map on page Status → Site.

10.2.5. Web interface personalization

Some graphical personalizations of the web interface of the device are possible from page Administration → General Setup → Web Interface, and will be valid for all the users.

• Logo: this allows to choose an image to replace the Nethix logo on the left top of the page.
• Prevalent color: Primary color of the page. (RGB hexadecimal color, for example: #007BC5)
• Secondary color: Secondary color of the page. (RGB Hexadecimal color, for example #009FE9)
• Font color: Color of the text. (RGB Hexadecimal color, for example #007BC5)
• White icons: Disabling this option, all the icons of the header (power-off, reboot, logout) will be displayed in black.
• Background color: Color of page’s background .(RGB Hexadecimal color for example #007BC5 )
• Footer: it allows to configure the footer at convenience (HTML code is allowed)

Clicking on all coloured fields, a “color picker” will allow to select the desired color and automatically insert the relevant hexadecimal value.
