Normal pulse edge function
With the standard pulse edge function, you can trans-
mit 1 bit, 2 bit, 4 bit priority control or 1 byte in steps
or infinitely.
Principle of the pulse edge function
Using the following diagrams, you can see how the
pulse edge function behaves when pulse edges rise or
fall.
Extended pulse edge function
With the extended pulse edge function, you have a wi-
der range of functions available, e. g. you can set diffe-
rent actions with a shorter or longer activation time,
which apply to both the actions which result when the
key is pressed and when the key is released. You can
also set a cycle time which can be parameterised for
each object.
| When parameterising, bear in mind that you
need to set all four types of key activation (brief/
long, pressing and releasing the key) in order to
ensure that the push-button (input) functions as
required.
