    Hi everyone,

    I’m having a trouble about communication with kepware OPC on window 10. I’m using Rapid SCADA vesion 5.1 and KEPServerEx 4.5. I used to try it on window 7 and it worked successfully, but it didn’t work on window 10.
    Here is the error:
    “Error creating data reading subscription: Exception from HRESULT: 0x80040202”

    Hopefully someone knows how to resolve this problem.
    Thanks everyone.

    Best regards,

    NITI

    Hi,

    The links that can help:
    Link 1
    Link 2 (See “Known issue of using OPC”)
    Link 3

    Does KEPServerEx provide OPC UA instead of OPC DA?

    Hi Mikhail,

    Thank you for your response.

    The KEPServerEx which I’m using it provides OPC DA.
    Here is its link: https://www.kepware.com/en-us/products/kepserverex/

    By the way, I’ve tried to fix the error by following your links, but this error still happened.
    Please let me know if you have any further clue for this case.

    Your sincerely,

    NITI

    KEPServerEX 6 expose all tags as OPC UA tags.

    I strongly recommend OPC UA instead of OPC classic when possible

    But now I still fighting why KpOpcUa failed to access NodeOPCUA server with BadIdentityTokenInvalid error. I’ll open a new thread about this problem later.
