ON delay
When an external input turns on, this function turns on the X signal after a certain time (input delay time) elapsed.
When the input delay time is set to a value larger than the scan time while the ON delay is used, the program can recognize
that the external input turns off even if its OFF time is short.
Even when the external input device is replaced, the program can be used as it is only by changing the setting value of the
input delay time.
■Operation of the ON delay
The following figure shows an operation example of the ON delay.
