    Hello
    I have been using Rapid Scada for some time to read Modbus values from a WAGO controller with Codesys 2.3. This works without any problems. When I try to do the same with a WAGO pfc100 controller, I have problems.
    The controller uses registers starting at 40000 and when I read these with Rapid I get values that I cannot interpret.
    Example: A value of 20 is output as 16800. With a Modbus scanner (Radzio), I also get this value displayed as a decimal value. When displayed as a 32bit float, the correct value appears. Where can I set the required number format in Rapid?

    Thanks
    Peter

    Hello,
    Usually, you should remove 4x from register address. Address of register 40000 is 0.

    Also, try specifying a byte order. For 16-bit float it could be 2301.
