5.1 Recognition of I/O Signals
An input time constant is set for the input signals of this controller to prevent malfunction due to chattering,
noise, etc.
Except for certain signals, the input signal will switch if the new signal level has remained for at least 6
[msec].
For example, when an input signal is turned ON, the controller will recognize that the signal is ON after
elapse of 6 [msec]. The same applies when the signal is turned OFF. (Fig. 1)
