      @Dmytro said in Error: "Write of group with index 3 skipped":

      Write Only On Change || False

      In a previous post was a mistake. Write Only On Change || True
      It causes error "Write of group with index 3 skipped"
      If that parameter has value False, error message in Port monitor disappears.

      Instead of that, Port monitor shows to me another problem:

      15.12.2021 14:37:40.3722 Timeout

      So I still cannot write the value to the register.

      Hello @sknobloch,
      accessing the Unipi Extensions over ModbusTCP is not possible at the moment, although we are thinking about it.

      You need to access the devices via ModbusRTU over the corresponding serial device. Here you can find the mapping of the physical RS485 ports: https://kb.unipi.technology/en:hw:02-neuron:portmap

      Best regards,
      Martin

      Hi @kalophain,
      that looks like you haven't "Attach the controller". Try following this tutorial: https://kb.unipi.technology/en:sw:01-mervis:creating-new-project-hidden#attaching_to_the_controller

      Best regards,

      Hello @Martin-Freundl,
      first of all, you shouldn't apply 24V to a 0-10V input. There are 12.5V transils on the input, so you probably burned it.

      The voltage measurement happens between the AI input and the AGND. The AGND is not connected to any other GND. Thats why you didn't measured any voltage between AGND and 24V.

      @sjp770 For sure! You still have the full access to the Linuy system and what you need is the latest development branch of evok which is under development and use a websocket connection to evok from node-red :)

      @Jan-Teunis Than everything should be working well. The RUN led also indicates if there has been a recent communication with the group (1-3).

      @Giamba or maybe @Martin-Kudláček, i'm using this program to control my dali controler which working fine now except from the switch function.
      When i push my my mometary switch on HMI and keep pushing it the light slowly increases or decreases at the next push. That's all working fine. But the switch function does work fine trough the g on the sel_0. Only problem is that when i start the plc the light is off (is ok) but the input on sel_0 is true so that results in no output on the sel_0. When i keep pushing the switch on the hmi the light increases on the output of the b30 counter but not on the output of the sel_0. Only when i realease the button the sel_0 output wil be the same as the output on the BD30 counter. After the sel_0 is high on the output and the lamp is on. i can switch the lamp on/off with a short push, no problem.
      What i need is : Long push > increase or decrease light (even if the plc is just turned on) short push > turn light on/off.
      Can anyone help me with this funtion to work fine?

      Many regrards,
