Why does an output from ABL/S 2.1 or AB/S 1.1 send only once or not at all?
In the logic modules, it is possible to parameterize the output reaction.
By default all outputs are set to only on output change. This means that an output will send only if in the logic a signal or value change acts on the output.
If so-called filter functions are used in the logic gates, cyclical signals are generated or even logical connections are used that must always have the same effect on the output, then the output must be set for every state change.
