The NEW_VAL signal is a pulse signal. The signal is set if the counter value was
updated since last report.
The SCAL_VAL signal consists of scaled value (according to parameter
Scale
), time
and status information.

Application
Pulse counter (PCGGIO) function counts externally generated binary pulses, for
instance pulses coming from an external energy meter, for calculation of energy
consumption values. The pulses are captured by the binary input module (BIO), and
read by the PCGGIO function. The number of pulses in the counter is reported via the
station bus to the substation automation system or read via the station monitoring
system as a service value. When using IEC 61850-8-1, a scaled service value is
available over the station bus.
The normal use for this function is the counting of energy pulses from external energy
meters. An optional number of inputs from the binary input module in IED can be used
for this purpose with a frequency of up to 35 Hz. PCGGIO can also be used as a general
purpose counter.
