3.3.4 Deactivating/reactivating the assignment of an interrupt routine (DISABLE,
ENABLE)
A SETINT statement can be deactivated with DISABLE and reactivated with ENABLE without
losing the input → interrupt routine assignment.
Syntax
DISABLE(<n>)
ENABLE(<n>)
Meaning
DISABLE(<n>): Command: Deactivating the interrupt routine assignment of input <n>
ENABLE(<n>): Command: Reactivating the interrupt routine assignment of input <n>
<n>: Parameter: Number of the interrupt signal
Type: INT
Range of values: 1 ... 32
Example
Program code Comment
N20 SETINT(3) PRIO=1 ABHEB_Z ; If input 3 switches, then interrupt
; routine "ABHEB_Z" should start.
...
N90 DISABLE(3) ; The SETINT statement from N20 is deactivated.
...
N130 ENABLE(3) ; The SETINT statement from N20 is reactivated.
...
3.3.5 Delete assignment of interrupt routine (CLRINT)
An interrupt signal assignment defined with SETINT for an NC program (ASUP) can be deleted
