    Hi. So I got RSLinx gateway.
    OPC test client can get and read tags.
    Rapidscada communicator seems to be having a hard time.
    So I connect to RSLinx OPC server instance.
    Expand data item folder.
    Next folder is my opc topic name then online.
    From there I can see my ladder logix rungs names.
    MainProgram.

    RSlinx OPC server
    +Data items
    +Online
    +MainPrograms

    When I click MainPrograms I get the same folder…

    RSlinx OPC server
    +Data items
    +Online
    +MainPrograms
    +MainPrograms

    This never stoops at any pieter.

    I haven’t tried connecting via OPC RSLinx, so I can’t recommend anything. Which Allen Bradley PLC do you want to read and through which interface ?

    Hi,

    Probably, they are a bit incompatible.
    You can do the following:
    1. Enter OPC tags in the Communicator settings manually. Use C:\SCADA\Projects\DemoProject.en-GB\Instances\Default\ScadaComm\Config\KpOpc_021.xml as example
    2. If a manufacturer of the OPC server supports OPC UA, use OPC UA instead of classic OPC.
