To enable debugging options using PI ICU, go to the OPCInt > Debug tab. In general, enable debug options for a short period of time, as they can bloat log files and reduce performance. For options marked "Technical Support only," enable only at the direction of AVEVA Technical Support.
For details about other command-line parameters, refer to the PI Universal Interface (UniInt) User Guide.
