The master station can freeze counted values with a "Freeze" command and then read them
as a "Frozen counter". Counted values that are assigned to an event class are stored in the
event memory as a "Frozen counter" event when the "Freeze" command is received.
Decrementing the counter reading is not supported.
Cnt01D_R / Cnt04D_R
Channel "CounterValueOutput_x"
Channel type: Counted value receive
The object always occupies 1 or 4 indexes (1 index per activated channel).
Cnt01D_R receives 1 counted value, Cnt04D_S receives 4 counted values from a station.
The objects can only be used in the master station.
As the data source, an S7 word variable with a range of validity of 0 to 65535 is specified for
each active channel. The value transferred by the S7 CPU is added up in the DNP3 TIM and
transferred as a 16-bit counted value to the DNP3 master station. When the CPU or DNP3
TIM is restarted and if there is overflow of the counted value, the corresponding flag (restart /
discontinuity) of the counter is set.
The master station can freeze counted values with a "Freeze" command and then read them
as a "Frozen counter". Counted values that are assigned to an event class are stored in the
event memory as a "Frozen counter" event when the "Freeze" command is received.
Cmd01B_S
Channel "CommandInputByte"
Channel type: Command send
The object occupies 1 index.
Cmd01B_S allows the sending of 1 binary value. Only the least significant bit 0 of the
transferred byte can be used. The object sends only when there is a 0→1 transition.
The object in a master station corresponds to the DNP3 object group 12 with the function
code "Direct Operate".
The command is sent with the interlock ID LATCH_ON. LATCH_OFF cannot be sent to a
station. For resetting the bit in the station (LATCH_OFF), see below (Cmd01B_R).
Special feature of the send trigger: For the Send at change of send trigger, only the values 0
and 1 can be set. Values higher than 1 are meaningless for command input.
