C.1.7 BINARY 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 âImmediate Freezeâ, âFreeze and
Clearâ etc. are accepted and F650 will respond with no objects and the IIN2-1 (Object Unknown) flag set. This behavior is
in conformance with DNP Level 2 Implementation (Document 28528: Level 2 DNP 3.00 Implementation).
