9-1 Quick-response Inputs
Quick-response inputs can be used with any model of CP2E CPU Unit.
The quick-response inputs can read pulses with an ON time as short as 50 µs even if they are shorter
than 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.
