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.
DNP3
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:
