Quick-response Inputs
Overview
The quick-response inputs can read pulses with an ON time shorter than the
cycle time (as short as 30
µ
s). Use the quick-response inputs to read signals
shorter than the cycle time, such as inputs from photomicrosensors.
Up to 8 quick-response inputs can be used in the X/XA CPU Units and up to 6
quick-response inputs can be used in the Y CPU Units.
PLC Setup
Use the CX-Programmer to set a built-in input as a quick-response input in the
PLC Setup. Click the Built-in Input Tab to display the Interrupt Input settings
(at the bottom of the tab). Set the input function from Normal to Quick for each
input that will be used as a quick-response input.
Bit Allocation for
Quick-Response
Inputs
The following diagrams show the input bits and terminals that can be used for
quick-response inputs in each CPU Unit.
X/XA CPU Units
The 8 input bits CIO 0.00 to CIO 0.03 and CIO 1.00 to CIO 1.03 can be used
as quick-response inputs.
