Table 4-2 Implementation of functions / objects and qualifiers
Those marked with grey background indicate objects, qualifiers and variations that are
supported by the smART P500, but are not part of the level 2 protocol implementation. The
relay responds to these objects and variations, but they are not required for operation
4.4. REPORTS BY EXCEPTION
The smART P500 runs a continuous process called “report by exception” where the
parameters are compared with the parameters reported to the master station that is
recovering information from the relay. If there are differences greater than the configured
dead bands, an event is generated.
When this happens, the event is sent to a queue that stores events in the order they are
detected. The event queue has a capacity of 99 events for binary inputs, 99 events for
analog points and 99 events for counters.
It is recommended to frequently scan the smART P500 in order to avoid these queues to
be filled and the loss of event data.
Another way to handle this situation is to expand the value of the configured dead bands to
minimize the number of events generated per unit of time, thereby reducing the amount of
information to be transferred out of the smART P500 to the master station and allowing the
scanning of information to be more efficient.
