Symbol/Operand
Sets up interrupt processing for I/O interrupts, input
MSKS(690)
interrupts, or scheduled interrupts. I/O interrupts, input
interrupts, and scheduled interrupts are masked (disabled)
N
when the PLC is first turned ON. MSKS(690) can be used
C
to unmask or mask interrupts and set the time intervals for
scheduled interrupts.
N: Interrupt number
C: Control data
Reads the current interrupt processing settings that were set with
MSKR(692)
MSKS(690).

D
N: Interrupt number
D: Destination word
Clears or retains recorded interrupt inputs for I/O interrupts
