6.5.3 BINARY / FROZEN COUNTER (OBJECTS 20/21)
The counters cannot be cleared with the Freeze/Clear function codes (9/10). Instead, the control relay output block
points can be used to clear groups of counters. There is only one copy of each counter, so clearing a counter via
Modbus or the front panel display causes the corresponding DNP counter point to be cleared and vice-versa.
