These event categories can be filtered within the DeltaV OPC AE server using the command arguments /EVCx= to specify the event category. (See the Command-line parameters section). Only those events specified in the command line argument will receive alarms and events from the server. Event categories are also filtered by the interface on a tag by tag basis using Location2 (See the PI Point configuration section).
