Summary:

ExperTune OPC Client crashes when trying to read OPC tags from Citect. It seems that Citect OPC server replies with an internal error code which is not handled properly by ExperTune OPC client. See the OPCAnalyzer screen shot below:

Solution:

Connecting the ExpertTune OPC Client to the remote Citect OPC server (Citect.OPCRemote) seems to solve the problem.
