C.7 BINARY COUNTERS APPENDIX C
C.7BINARY COUNTERS
Currently there are no Binary Counters in the G650 relay. Nevertheless G650 accepts requests of DNP objects 20 (Binary
Counters), 21 (Frozen Counters) and 22 (Counter Change Events). Function codes "Immediate Freeze", "Freeze and
Clear" etc. are accepted and G650 will respond with no objects and the IIN2-1 (Object Unknown) flag set. This behaviour is
in conformance with DNP Level 2 Implementation (Document 28528: Level 2 DNP 3.00 Implementation).
