Examples
Example 1: Assign interrupt routines and define the priority
Program code Comments
...
N20 SETINT(3) PRIO=1 ABHEB_Z ; If input 3 switches, then interrupt routine
"ABHEB_Z" should start.
N30 SETINT(2) PRIO=2 ABHEB_X ; If input 2 switches, then interrupt routine
"ABHEB_X" should start.
...
The interrupt routines are executed in the sequence of the priority values if the inputs
become available simultaneously (are energized simultaneously): First "ABHEB_Z", the
"ABHEB_X".
Example 2: Newly assign an interrupt routine
Program code Comments
...
N20 SETINT(3) PRIO=2 ABHEB_Z ; If input 3 switches, then interrupt routine
"ABHEB_Z" should start.
…
N120 SETINT(3) PRIO=1 ABHEB_X ; Input 3 is assigned to a new interrupt
routine: Instead of "ABHEB_Z", "ABHEB_X"
should start if input 3 switches.
