Interrupt Functions
Section 6-1
Operation
When execution condition W0.00 goes ON, MSKS(690) is executed to enable
CIO 0.00 as an up-differentiated input interrupt.
If CIO 0.00 goes from OFF to ON (up-differentiation), processing of the cyclic
task that is currently being executed will be interrupted and processing of
interrupt task 140 will start. When the interrupt task processing is completed,
processing of the interrupted ladder program will restart.
Restrictions
Inputs cannot be used for input interrupts when they are being used as gen-
eral-purpose (normal) inputs or quick-response inputs.
6-1-3
Input Interrupts (Counter Mode)
Overview
This function counts up-differentiated or down-differentiated input signals and
executes an interrupt task when the count reaches the set value.
• The counter-mode input interrupts use the same input terminals as the
direct-mode input interrupts. Refer to
6-1-2 Input Interrupts (Direct Mode)
for details.
• The counter input mode can be set to up or down (incrementing or decre-
menting) with MSKS(690).
• The counter-mode input interrupts start the same interrupt tasks (140 to
145) as the direct-mode input interrupts.
• The maximum input response frequency is 5 kHz total for all counter-
mode input interrupts.

*Input interrupts 4 and 5 are not supported by CPU Units with 14 I/O Points.
