5-1 Overview
By setting an input on the Pulse I/O Module to quick-response input operation, inputs with signal widths
as small as 30 µs can be read with certainty regardless of the cycle time. Use the quick-response inputs
to read signals shorter than the cycle time, such as inputs from photomicrosensors.
The pulse widths of quick-response input signals must meet the following conditions.
