1. Overview

DIS500 is a programmable display for control panels, suitable to communicate through Modbus RTU protocol on serial port RS232 and RS485. It can be used as a slave device for displaying the data managed by the WE300 and WE500. Having a Master port RS485 on board it can also interrogate slave devices (as for example the expansion modules XP500) and operate as a Modbus gateway. The configuration of the functions and registers of DIS500 can be performed through the Software DIS Configurator.

DIS500 is compatible with the whole range of Nethix products, nevertheless it can be used with any other device, supporting the standard Modbus protocol.

In this section all technical specifications of the device are described.

The buttons allow to browse through the available pages inside DIS500 and may have different functions according to the visualization type:

IN VISUALIZATION MODE

The buttons allow to browse through the graphical pages.

Press the button button_up to scroll upwards and button_down to scroll downwards

The buttons have no effect, if a single page is loaded.

ACCESS TO THE PRESET MENU

In order to enter the preset Menu, where it’s possible to change the value of the configured registers, keep the button button_right pressed and press button_up.

Use the buttons button_up and button_down to select the parameter to be modified. Once found the desired parameter, press button_4 to highlight the first character of the parameter and then use the buttons button_up and button_down to scroll the available numbers/characters. Once set the required character/number on this position, press the buttons button_right and button_left to skip to the following (or to the previous).

To confirm the modifications press the button button_4; in alternative, to escape and cancel the modifications made, push the button button_3.

ENTER THE CONFIG MENU

For entering the config Menu, it’s necessary to pass through the preset menu. From the preset menu, press the button button_1.

Once entered the config menu, it’s possible to proceed with the visualization/modification of some general parameters of the device:

  • Baud485 it shows the communication speed of the RS485 slave port
  • Baud232 it shows the communication speed of the RS23D slave port
  • Master it shows the communication speed of the RS485 Master port
  • Address it shows the Modbus address of the device
  • Bright it allows to change the brightness of the display, setting a value between 1 (minimum) and 15 (maximum)
  • Contrast it allows to set the display contrast. The positive values go from 1 (minimum) up to 15 (maximum), the negative from 16 (minimum) up to 31 (maximum)
  • Firmware it shows the firmware version currently installed on the device
  • Status it shows the operative condition of the device: RUN means that the device is working, STOP indicates that no program has been loaded in the device yet.

To select the parameter, that has to be changed, it’s required to push the buttons button_up and button_down to scroll up and down the list. Once found the required parameter, push the button button_4 to change it and use button_up and button_down to scroll through the different available options.

To confirm the modifications, just press the button button_4, or press button_3 to cancel the modifications and return to the main page.

3.2 Rear view and terminals

On the backside of the DIS500 are available all clamps for the power supply connection, for the serial ports and the RJ45 connector.

4. INIT mode

At any time the DIS500 can be set in INIT mode, in order to have it back to a known condition and be able to communicate with it. For restoring the INIT mode, make the connection as shown on the picture below, having the device turned off.

../_images/init.png

The communication parameters in INIT mode are:

  • Baudrate 9600
  • Slave address 10

Using the above mentioned parameters and the software DIS Configurator, set a speed value and a slave address. To make the modifications effective, just turn off the DIS500, remove the connection to the clamp INIT and reboot the device.
