Interrupt Functions Section 5-1
Input Terminal Arrangement
Setting the Input Functions in the PLC Setup
Normally, bits CIO 0.00 to CIO 0.03 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.
Y CPU Units The 6 input bits CIO 0.00 to CIO 0.01 and CIO 1.00 to CIO 1.03 can be used
for input interrupts.
