The Inhibit tab enables you to inhibit various aspects of the Virtual Flow Computer (VFC), which in turn, changes what the Controller sees. Applying these filters can reduce the number of nuisance alarms that are listed in the Alarm Summary, as well as the number of events listed in the Event Summary.
To inhibit alarms and events associated with the VFC
-
Open the virtualflowcomputer record. For more information on opening a virtualflowcomputer record, see Open a Virtual Flow Computer record.
