Leds TM172DGRP monochrome panel

[inspro]

Hello
I have a TM172PDG28RI controller and a TM172DGRP monochrome panel
The TM172DGRP panel has three leds
Question:
How to make the leds on the TM172DGRP panel reflect those on the TM172PDG28RI controller (red/yellow/green)
I assumed that this was done automatically after setting up communication, but the LEDs did not light up.
I have the same configuration for the display on the controller and remote panel

You need to control the LED via Display part. You could find a sample for this in the integrated TVDAs Chiller Large/ AHU Large. 

You need to create a Global Procedure to activate the LEDs.

And you need to read the status for the LED mostly via Video_GetParam function.

You could find here the TVDAs

Thank you Bastian for your help
I can control LEDs on the operator screen turn off and on the LEDs by manually entering the values ​​in the variable:usiLEDsCPU: USINT Array (0...2)
I have a problem with the GetParam function. I entered in GlobalOnTimer:

uiRET := Video_GetParam( 0, sysLocalLeds, 0, usiLEDsCPU, tyUSInt);
sysLocalLeds:= usiLEDsCPU;

There is no error during download, but the LEDs on the panel do not work.
Can you write what I did wrong?

I am a beginner in programming Medicon controllers. I work mainly with Siemens controllers and the TIA portal program.What is very simple in Scheider Electric is difficult and vice versa 🙂

You need to specify the modbus Register of sysLocalLeds in the function Video_getParam. In the TVDA all variabels which are written in UPPERCASE are constanst for the register adress. In you case you need to enter as adress 8640 LED1 8641 LED2 8642 LED.
