Functionality

The pulse counter for energy measurement function 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. The number of pulses in the counter is

then reported via the station bus to the automation system or read via the station

monitoring system as a service value. The scaled value is also available over IEC

61850 communication.

The pulses are captured by the binary input module and read by PCGAPC with a

frequency of up to 40 Hz. PCGAPC can also be used as a general-purpose counter.

Operation principle

The function can be enabled and disabled with the

corresponding parameter values are "on" and "off".

The operation of PCGAPC can be described with a module diagram. All the modules

in the diagram are explained in the next sections.
