Hi
My english isn't very good.
please bear with me.

The OPC Server at a particular site is experiencing this error.

Old version : OPC Client Program OPC 5.60.107
Current Version : OPC Client Program OPC 5.63.246

Logic to get data from the OPC Server. (The current version logic is the same as the old version)

I have upgraded site to the current version, but it does not work with the current version.
The site receives data well from the old version (OPC 5.60.107) but the following error occurs from the current version (OPC 5.63.246)
On other OPC servers, the current version (OPC 5.63.246) also works well.
