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.
