The error may come from the OPC AddGroup call and may mean that the client is creating OPC groups with duplicate names. But it is not. With 99% certainty, the OPC server vendor needs to fix the server. Tell them that we are passing an empty string to AddGroup as a group name, and that means that they should create their own names - unique ones.

Thanks for the reply.

The OPC Server comes from the German company "Schille" called "video management OPC"

When I change values but with an OPC client it works.

It might have a different problem?

This is generated inside the target OPC server - please contact the vendor and ask them why they return this error.

BTW, which OPC server are you connecting to?

Hello, maybe someone can help me.

I use the easyDAClient, once I write a value on an ItemID with WriteItemValue or WriteMultipleItemValues I can query more no other ItemID's via ReadItemValue or ReadMultipleItemValues.

The following is the error message "failure-1073479668 (0xC004000C): duplicate name not allowed"
