Description of the function
The output is set, when input En is set and the 'Status' parameter is set to 'On' and
confirmed with OK. This action is performed irrespective of a configured switch or
pushbutton function.
The output is reset to '0' in the following threes cases:
With a 1 to 0 signal transition at input En.
When a pushbutton function is configured and one cycle has expired after its
actuation.
When the 'Status' parameter sets the 'Off' status in configuration mode, and this
has been confirmed with OK.
Particular characteristics to be noted when configuring
The softkey can be used both with momentary pushbutton or switching action. At the
status parameter you can define the on (actuated) or off state for the switch/pushbutton.
If the softkey is assigned a pushbutton action, the output is always set for the duration of
one cycle with a 0 to 1 transition at input En when the pushbutton is in on state, or if the
pushbutton state changes from Off to On when En=1.
