An interrupt can be assigned a priority value from 1 ... 128. Priority value 1 corresponds to the
highest priority and 128 the lowest.

Input <n> is assigned the interrupt routine <Name>. The assigned interrupt routine
is started as soon as input <n> == 1 is detected.
Note:
If an already programmed input <n> is assigned another interrupt routine, then the
previous assignment is no longer effective.
Input number
Type: INT
Range of values: 1 ... 8
Priority of the interrupt
(optional)
Priority value
(optional)
Type: INT
Range of values: 1 ... 128 (1 ⇒ highest priority)
Name of the interrupt routine (subprogram)
BLSYNC ensures that after initiating the interrupt, the system first waits until the
actual block has been completed. Only then is the interrupt routine executed.
(optional)
LIFTFAST ensures that after initiating the interrupt, initially a fast retraction is
realized (see Chapter "Fast retraction from the contour (SETINT LIFTFAST, ALF)
(Page 544)"). Only then is the interrupt routine executed.
