6-1-2 Input Interrupts (Direct Mode)
This function executes an interrupt task when the corresponding input signal
(up or down differentiated) is received.
Input Interrupt Bit and
Terminal Allocations
The following diagrams show the input bits and terminals that are used for the
input interrupt function in each CPU Unit.
Input Terminal Block of
CPU Units with 14 I/O
Points The 4 input bits CIO 0.04 to CIO 0.07 can be used for input interrupts.
Input Terminal Block of
CPU Units with 20 I/O
Points The 6 input bits CIO 0.04 to CIO 0.09 can be used for input interrupts.
