FAQ
Receiving short pulses
The programmable controller cannot receive short pulses.
Answer
In order for the programmable controller to receive input pulses completely, the ON duration and OFF duration of inputs in the programmable controller require longer time than "input filter time (10 ms) + one scan time".
When the ON duration and OFF duration are shorter than "input filter time (10 ms) + one scan time", use the input filter value adjustment function, the input interrupt function, the pulse catch function, or the high-speed counter function.
When the ON duration and OFF duration are shorter than "input filter time (10 ms) + one scan time", use the input filter value adjustment function, the input interrupt function, the pulse catch function, or the high-speed counter function.
