Interrupt Functions
Procedure
190
Setting the Input Functions in the PLC Setup
Normally, bits CIO 0.00 to CIO 0.01 and CIO 1.00 to CIO 1.03 are used as
normal inputs. When using these inputs for input interrupts, use the CX-Pro-
grammer to change the input's setting in the PLC Setup.

• Determine the inputs to be used for input
interrupts and corresponding task numbers.
• Wire the inputs.
• Use the CX-Programmer to select the inter-
rupt inputs in the PLC Setup.
• 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).
