active counters can also be read by the LON General Interrogation command (GI) or
IEC 61850.
Pulse counter (PCGGIO) function in the IED supports unidirectional incremental
counters. That means only positive values are possible. The counter uses a 32 bit
format, that is, the reported value is a 32-bit, signed integer with a range
0...+2147483647. The counter is reset at initialization of the IED.
The reported value to station HMI over the station bus contains Identity, Scaled Value
(pulse count x scale), Time, and Pulse Counter Quality. The Pulse Counter Quality
consists of:
• Invalid (board hardware error or configuration error)
• Wrapped around
• Blocked
• Adjusted
The transmission of the counter value by SPA can be done as a service value, that is,
the value frozen in the last integration cycle is read by the station HMI from the
database. PCGGIO updates the value in the database when an integration cycle is
finished and activates the NEW_VAL signal in the function block. This signal can be
connected to an Event function block, be time tagged, and transmitted to the station
HMI. This time corresponds to the time when the value was frozen by the function.
The pulse counter function requires a binary input card, BIMp, that is
specially adapted to the pulse counter function.
Figure 481 shows the pulse counter function block with connections of the inputs and
outputs.
