Application Override Events

When Application Override is in effect, the permissions for the point(s) in the "target" services are superseded by the permissions for the PNT or FAC component-level security. The target services are: AUD, CAS, current value services (UIS, HSS, OPCIS, and SVCMON), FAC, and VHS.

This requires that the component-level security be defined using the same Events as those applicable to the target service. The table below lists Events that are affected by Application Override. See Security Reference for a full list of Events for each service and the authorization level required to perform the task(s) specific to each Event.
