2.1.19 Set Priority Queues
Y ES or N O
This section defines priority queues for the gateway. You can assign priorities to
data types that return events so that events of some data types will be returned
before events of other data types. If this feature is utilized, each data type must
be assigned a unique index from 0 to 7. The lower the index, the higher the
priority (0=highest priority, 7=lowest priority).
Events of ASDUs with lower numbers will be reported before events from other
ASDUs with higher numbers.
Note: In some configurations, depending on the total number of events generated for all data
types, setting priorities may cause some events to be lost, as the event buffers for low priority
queues may overflow before their events can be reported.
For more information, refer to Event Priority (page 31).
