When input data changes to OFF, the input data is read five times for the
period of the set interval (1/5 of the OFF response time). If all values are OFF,
the input is turned OFF. The OFF timing is delayed according to the length of
the OFF response time.
The input filter can also be used for ON/OFF delay operations.
To use a pulse shorter than the communications cycle time, set the OFF
response time to a value longer than the communications cycle time. (If the
input pulse is short, the input may remain ON.)
