Interrupt Control Instructions Section 3-20
Setting the Time to the First Scheduled Interrupt
1. When W00000 goes from OFF to ON, CLI(691) sets the time to the first
execution of scheduled interrupt 0 to 24 ms. (In this case, the scheduled
time interval units are set to 1 ms in the PLC Setup.)
2. When W00001 goes from OFF to ON, CLI(691) sets the time to the first
execution of scheduled interrupt 0 to 12 ms, and starts the internal timer.
(In this case, the scheduled time interval units are set to 1 ms in the PLC
Setup.)
3-20-4 DISABLE INTERRUPTS: DI(693)
Purpose Disables execution of all interrupt tasks except the power OFF interrupt.
When a CS1D CPU Unit for Single-CPU System or a CS1-H, CJ1-H, or CJ1M
CPU Unit is being used and the power OFF interrupt task is disabled, it is pos-
sible to disable power OFF interrupt processing simultaneously.
