C.7 BINARY COUNTERS

C.7BINARY COUNTERS

Currently there are no Binary Counters in the F650 relay. Nevertheless F650 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 F650 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).
