The outputs AVA_POWER and ACTIVE_POWER are reported for the monitoring
view.
The ACTIVE_POWER (active power), slow load-shedding start and slow load trigger
inhibition signals are reported to the Binary to Integer module.

Binary to integer module

The DATA_SOURCE output provides the load-shedding data for the power source.
The data is also available in the monitoring view.
The DATA_SOURCE output consists of various binary information as shown in
269.
Based on the Source configure setting, the Binary to integer module calculates the
power source configuration status.
If the Source configure setting is set to "Generator", the power source configuration
status is FALSE. If the Source configure setting is set to "External source", the power
source configuration status is TRUE.
If the ACTIVE_POWER output is positive, the overcurrent operation status, maximum
demand operation status and external slow load-shedding trigger remain same as
received from the respective modules.
If the ACTIVE_POWER output is negative, the overcurrent operation status,
maximum demand operation status and external slow load-shedding trigger are
FALSE.
If the CB_COMPS_POS output is "Close", the compensated circuit breaker close
status is TRUE, else compensated circuit breaker close status is FALSE. If the
CB_COMPS_POS output is "Open" and FLS_TRIGGER is TRUE, the compensated
circuit breaker open status is FALSE.
Irrespective of the CB_COMPS_POS output, the compensated circuit breaker open
status is TRUE if the FLS_TRIGGER is FALSE.
