    Hi
    I am currently using Rapid SCADA as my Modbus client. I am connecting to a simulated Modbus server using Modbus simulation software, and the connection is successful. However, I am unable to use commands with function codes to change the value of my channel 101.

    I have checked my channels table, and the output formula is properly configured. There are also no errors in the ‘Commands (Total/Errors)’ section. Could you please help me take a look at what might be the issue? Thank you.

    Output Formula is not a channel number, but a formula.
    Command Code = tag 4 and not just 4
