  • modbus protocol

    Hello everyone,

    maybe someone use a modbus protocol in 4dgl displays?

    One way I can see doing this is to use an RS485 (typical modbus) to RS232 converter and then treat the signal as a simple serial. I have looked at using RS485 to TCP/IP and RS232 convertor but have not had to use one yet.

    Considering the code requirements is giving me a headache on how to interpret the data.

    I use a DA Server to collect all my WonderWare data via Modbus and other protocols. It does the hard work for me so I just have to worry about the WW code side of things.
