    Hi,
    I got a problem to communicate with OPC DA Server.

    https://ibb.co/Z2jN5KG

    it stops communicating with the server after add tags.

    How can i debug it？

    Hi,

    OPC DA is a black box. I strongly recommend to move to OPC UA because it is more reliable, and .NET5 and higher will not support classic OPC.
    I can provide the source code of the driver if needed.
    Also try this advice.
