Citect Scada 2018 read variables in remote OFS OPC DA

Thomas

Hello,

I have a problem to connect Citect Scada 2018 to a remote OFS (OPC Factory server) on a remote computer.

I already made the differents settings for DCOM communication : on my local machine, if I open OFS Client, and try to connect to the remote OFS Server, the services start correctly and my client can connect to remote server (I can see variables from my M580)

The problem I have is how to create IOServer or how to configure the IO server in Citect Scada to connect to my remote server.

I already created an IO Device and my Citect Scada imported all the variables. But when I map an imported variable on a view and launch the runtime, communication doesn't works and services on the remote computer doesn't start.

Do you have any advice ?

Thank you

  • Hello,

    It's ok for me, the settings in my application was good as you told me. I used the OPC DA client driver, an IO device in IO server, using the OPC protocol and address the OFS progID, and special options in OPC Board.

    My problem was about the Windows user, I created a Windows userwith the same Name and the same password on both devices (my client computer and my remote server) and now it's working.
    I think my application wasn't able to reach my remote OFS because the remote server didn't see the good Windows user and password.

    Thanks for your help.

    Good solution, I have the same problem but there is one difference in the DCOM settings, a domain is used and I don't know how to reconfigure the domain to make it work
