The following output options can be used for command data points:
●

The function is encoded by the master via the Control Code of the object.
–
Control Code, Operation Type field (OP Type) - Volume 6, Part 2, Objects
The master permanently latches a command output to the value 0 or 1.
The station processes the command according to the Complementary Latch Model.

count" with the command frame to the station.
The station data point evaluates the information and checks it for consistency with the
parameters "Max. pulse duration", "Pulse duration replacement time" and "Max. number
of pulses".
The TIM 1531 IRC processes the command according to the Activation Model.
