Interrupt Functions Section 6-1
Setting the Input Functions in the PLC Setup
Normally, bits CIO 0.04 to CIO 0.09 are used as normal inputs. When using
these inputs for input interrupts, use the CX-Programmer to change the
input’s setting in the PLC Setup.
Note *Input interrupts 4 and 5 are not supported by CPU Units with 10 or 14 I/O
Points.
**Input interrupts 2 and 3 are not supported by CPU Units with 10 I/O Points.

Select the input interrupts.
• Determine the inputs to be used for input
interrupts and corresponding task numbers.
↓
Wire the inputs. • Wire the inputs.
↓
Set the PLC Setup.
• Use the CX-Programmer to select the inter-
rupt inputs in the PLC Setup.
↓
Write the ladder program.
• Write the programs for the corresponding
interrupt task numbers.
• Use MSKS(690) to specify up-differentiation
or down-differentiation.
• Use MSKS(690) to enable input interrupts (in
direct mode).
