Replied by support on topic What endpoint is used to read/write from the client to OPC server?

Hello,
before I answer the question, I'd like to clarify one thing: Do you want to use OPC Classic (COM/DCOM-based), or OPC Unified Architecture?

I am asking this question because your post mixes up the two.

You are referring to methods on the EasyDAClient, which is for OPC Classic. But at the same time, you are mentioning "opc.tcp:", which is a scheme that is *only* used with OPC Unified Architecture.

Best regards

What endpoint is used to read/write from the client to OPC server? was created by aris

How does EasyDAClient::WriteItemValue build opc endpoint to send the data to OPC server? Is it in the form of "opc.tcp://..."? If it is, can someone give a full example of such endpoint when I do WriteItemValue(new DAItemValueArguments(ServerAddress,ServerIdentifier, tagName, val));?
