● PULSE_ON/OFF
The function is coded by the master via a "Qualifier of command". The following codings
are evaluated by the communication module in the station:
– QU (Type 1.1) <1> short pulse duration
Corresponding parameter for the module: "Short pulse duration"
– QU (Type 1.1) <2> long pulse duration
Corresponding parameter for the module: "Long pulse duration"
– S/E (Type 6) <0> execute
Corresponding parameter for the module: "Command execution mode"
– S/E (Type 6) <1> select
Corresponding parameter for the module: "Command execution mode"
For parameter assignment see below.
The two functions are encoded by the master via the control code of the object.
● LATCH_ON/OFF
The function latches the value of a command as described above.
● PULSE_ON/OFF
The function evaluates the number of pulses and duration.
The master sends a "Control Code" to the station with the "PULSE_ON" function with
information on the "Count", "On-time" and "Off-time". The data point of the
communication module in the station evaluates this information via the parameters "Max.
pulse duration", "Pulse duration replacement time" and "Max. number of pulses".
The following encodings of the control code are evaluated by the data point:
Table 4- 10 DNP3 Control Codes
Reaction of data point upon activation of:
0x01 NUL PULSE_ON
The output is set to 1 for the
"Max. pulse duration".
The command is rejected.
0x03 NUL LATCH_ON The command is rejected.
The output is set permanently
to 1.
0x04 NUL LATCH_OFF The command is rejected.
The output is set permanently
to 0.
0x41 CLOSE PULSE_ON
The output is set permanently
to 1.
The command is rejected.
0x81 TRIP PULSE_ON
The output is set permanently
to 0.
The command is rejected.
The clear field (CR) is not evaluated.
The count field is always = 1.
