The input response times for CS/CJ Basic I/O Units can be set by Rack and
Slot number. Increasing the input response time reduces the effects of chat-
tering and noise. Decreasing the input response time (but keeping the pulse
width longer than the cycle time) allows reception of shorter input pulses.
Note With CS-series CPU Units, pulses shorter than the cycle time can be input
with the high-speed inputs available in some C200H High-density I/O Units or
with a High-speed Input Unit. Refer to 6-1-4 High-speed Inputs for details.
