Functional description
In parameter assignment mode, the output is set with a sig-
nal at input En, if the ‘Switch’ parameter is set to ‘On’ and
confirmed with
OK
. Whether the function was configured for
pushbutton or switching action is here of no concern.
The output is reset to ‘0’ in the following three cases:
•
After a 0 to 1 transition at input En.
•
When the function was configured for momentary push-
button action, and one cycle has expired since it was
switched on.
•
When the position ‘Off’ was selected at the ‘Switch’ pa-
rameter and confirmed with
OK
in parameter assignment
mode.
If retentivity is not set, output Q is initialized after a power fail-
ure according to your configuration at the “Start” parameter.
