9.10 Asynchronous subroutines (ASUBs), interrupt routines

Interrupt routines sequences may be generated for which there is no unambiguous return to an interruption point

in the block processing sequence (REPOS).

The system variable $P_REPINF can be used to scan the ASUB to determine whether a REPOS is possible.

Repositioning with REPOS not possible because:

not called in ASUB

ASUB ran from reset status

ASUB ran from JOG

Repositioning with REPOS possible in ASUB

Determine cause of activation

With the system variable $AC_ASUP the cause leading to the activation of an intrerrupt routine, is specified bit-

coded and can be read in the part program and in synchronous actions (see "Programming [Page 605]").

Flexible programming

The following commands help in the flexible programming of interrupt routines:

Programming Manual, Job Planning; Chapter: "Flexible NC Programming" > "Interrupt routine (ASUB)"

If the SAVE command has been used to define the interrupt routine, the G

codes, frames and transformations previously active in the interrupted

part program become operative again as soon as the interrupt routine is

The DISABLE command can be set to protect part program sections from

being interrupted by an interrupt routine.

The assignment interrupt signal ↔ part program is maintained but the

interrupt routine no longer respond to the 0/1 signal transition.

The DISABLE command can be reset with the ENABLE command.

Interrupt routines are not activated until the next 0/1 transition of the

interrupt signal.
