    I have a machine that communicates to a windows PC via OPC-DA. The windows PC has an OPC server on it called OCIF. I want to get that OPC data to another computer on the network. Should I only install Communicator on the OPC-DA computer?

    It’s enough to install Communicator and Agent to that computer. The Agent service is needed to upload the project and restart Communicator.

    Is this roughly how my network should be?

    Perhaps, you need a central Rapid SCADA instance to collect data from all PCs.

    Rapidscada will not run on a WindowsXP machine correct?

    One last question. My computer has FSGateway running on it. Can I connect to it using Rapidscada to access the OPC data on that machine?

    System requirements are here.
    Minimum Windows 10.

    Likely, yes.

    Just wanted to say thank you. I was able to get your software to recognize an OPCUA server and its all working now. My next question is, if I want to work on an project on one PC and then copy it over to another PC how do I do that? I have a laptop I do all my programming on and want to program on it. But then take the project to another computer and get it running on that computer.

    That’s nice.

    Please create a separate topic for that question.

    While testing the conversion from OPC DA to OPC UA, I encountered an issue where an error occurs if I do not install the OPC Core Components Redistributable (x64) 3.00.108. However, my production environment only supports 32-bit systems. So, how can I configure Rapid SCADA to use the runtime of OPC Core Components Redistributable (x86) 3.00.108 instead? Error code is 0x80040154
