0: Recorded interrupt input retained
1: Recorded interrupt input cleared
Example for C200HS-INT01
When CIO 000000 turns ON in the following example, CLI(691) clears the
recorded interrupts for interrupt inputs 3 and 6 in Interrupt Input Unit 2.
Example for Setting Time to First Scheduled Interrupt
When CIO 000000 turns ON in the following example, CLI(691) sets the time
to the first execution of scheduled interrupt 2 to 50 seconds.
(In this case, the scheduled time interval units are set to 10 ms in the PLC
Setup.)
Disables execution of all interrupt tasks except the power OFF interrupt.
When a CS1-H, CJ1-H, and CJ1M CPU Unit is being used and the power
OFF interrupt task is disabled, it is possible to disable power OFF interrupt
processing simultaneously.

OK
DI(693) is executed from the main program to temporarily disable all interrupt
tasks except the power OFF interrupt (I/O interrupts, scheduled interrupts,
and external interrupts).
All interrupt tasks will be disabled until they are enabled again by execution of
EI(694).
