Setting the Input Response Time for Basic I/O Units
The input response times for Basic I/O Units can be set by Rack and Slot number. Increasing the
input response time reduces the effects of chattering and noise. Decreasing the input response time
(but keeping the pulse width longer than the cycle time) allows reception of shorter input pulses.
Note Pulses shorter than the cycle time can be input with a High-speed Input Unit. Refer to 10-2-4 High-speed
Inputs for details.
