Delayed One Shot Block

This block is equivalent to a combination of the Delay and the One Shot function block. Set an
ON delay for the rising pulse of the Input signal or an OFF delay for the falling pulse. This FB
will process the ON delay time before turning the Output ON for the OneShot pulse time and/or
delay the Output resetting until the OFF delay time has processed.

Function
Note: The set time cannot be less than one scan time for the controller; otherwise, the Delayed
One Shot Function Block will not perform its assigned task for the time specified. Users can
monitor the scan time from the
user- program; therefore, caution is needed as and when time units are selected.
1 ) Delayed One-Shot (Delay starts when OFF to ON)
2 ) Delayed One-Shot (Delay starts when ON to OFF.
