5.6.22 Set Priority Queues
Y ES or N O
This section defines priority queues for the module. You can assign priorities to
data types that can return events so that events of M_IT_NA data types will be
returned before other data types. This may cause events to be lost as the event
buffers for low priority queues may overflow. 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).
Each of the ASDUs affected by this feature must be assigned a unique priority
index from 0 to 7. Events of the ASDU with a priority of 0 will always be reported
before any others when they are present.
For more information, refer to Event Priority (page 172).
