  • Passing Parameters to Modbus Read and Write Instructions

    Hi,

    It doesn't like there is a way to currently do this. I have hundreds of the same devices communicating on Modbus but with different Slave IDs. However, the Modbus Read and Write instructions have these parameters as constants... so unfortunately I cannot write a routine and just pass values back and forth.

    Does anyone know of a way to do this where I can use the same code.
    Also, is there a way that I can send a feature request for this?

    Thanks,

    Jules

    You are correct. Currently there is no way to use a tag to index different slave addresses. We will look into what it takes to add this feature.

    Thanks for your input!

      Do we have an estimated time frame on this feature? I have a couple weeks worth of work ahead of me in copy and paste which I'm dreading.. but with this feature it would be just a few hours of coding.
