    Hi,

    Another question:
    I have to read a Modbus value (rs485) from a power meter (hager EC367M) and show usage in an actionpad.
    Can I do this with the sympl serial node?

    Hi Robbert

    With the SYMPL serial Node you can communicate over an RS232 and an RS485 interface.
    We do not provide libraries regarding the commands of different connectable devices, in your case the hager power meter.
    But you can send binary values to the connected device and also receive messages.
    Here it might be helpful to parse the messages in a C# script with the scripting engine.

    I hope, this helps.

      Thanks, all we need to do is get a number (power usage) out of the meter and show it in the actionpad.
      I’ll guess it should be doable.

      Will give it a try.

    Ahh, one hint.
    In the actual firmware the parities “even” and “odd” are switched.
    So if you need a parity bit and it does not work, try the other setting.
