Event Priority
Event Priority permits ASDUs that generate events to be placed in priority
queues that are set by the user. The configuration file contains the following
parameters to support this feature:
The Set Priority Queues parameter must be enabled for this feature to be used.
Each of the ASDU’s affected by this feature must be assigned a unique priority
index from 0 to 6. Events of the ASDU with a priority of 0 will always be reported
before any others when they are present.
