Reconnection to Schneider OPC Factory Server

"OPC Operation Failure..." are generally errors returned by the target OPC Server. First thing to do is to examine the details of the inner exception of this exception.

I am using QuickOPC .NET 5.22 Build 296.1 talking to a Schneider OFS OPC server. When the underlying PLC is power cycled, writes start returning "OPC Operation Failure". When I restart our application, everything works (until the PLC is subsequently power cycled).

Any suggestions?
