Hi;

I need some assistance configuring PI OPC interface.

So far PI OPC client is working fine and reading the value successfully from an Experion OPC Server (HWHsc.OPCServer)

But reading the same tag in PI shows the following error:

“Developer load structure failure… Can not have polled tag in scan class 1”

Instrument tag is the same as what is shown in ItemID on  the PIOPC client.

Appreciate your help.
