3.20.14.5 Application
PCGAPC counts externally generated binary pulses, for example, pulses coming
from an external energy meter, for the calculation of energy consumption values.
The pulses are captured by the binary input module and read by PCGAPC with a
frequency of up to 40 Hz. The number of pulses in the counter is then reported
via the station bus to the substation automation system or read via the station
monitoring system as a service value. When using IEC 61850, a scaled service value
is available over the station bus.
