9 Quick-response Inputs
9-4
CP1E CPU Unit Software User’s Manual(W480)
The following terminals can be used for quick-response inputs.
Input Terminal Block on CPU Unit with 20 I/O Points
Pulse inputs shorter than the cycle time can be read in the CPU Unit I/O memory using normal instruc-
tions. Simply set the interrupt setting for the required input to Quick in the PLC Setup.
The status of CIO 0.02 to CIO 0.07 can be read using instructions such as the LD instruction.
Example: Setting IN2 to Quick in the PLC Setup Interrupt Settings.
• The minimum pulse width (ON time) that can be read for a quick-response input is 50 µs.
• The status of the input that is stored in the I/O memory for a short input will be cleared during the next
I/O refresh period.
