14.8 Interruption subroutines.
The interruption subroutines are defined by the machine manufacturer and will be executed
from the PLC. When the PLC commands the execution of one of these subroutines, the
channel interrupts the execution of the program and executes the corresponding interruption
subroutine.
If the program is already interrupted (STOP) or no program is in execution (channel in
READY state), the execution of the subroutine depends on parameter SUBINTSTOP. Also,
in order to execute the subroutine when no program is in execution, the channel must be
in automatic mode; the subroutine cannot be executed from jog mode.
The CNC executes the subroutine with the current history of the interrupted program (G
functions, feedrate, etc.). Once the subroutine is executed, the CNC resumes the execution
of the program from the interruption point and maintaining the changes made to the history
by the subroutine (G functions, etc.).
The execution of an interruption subroutine may be interrupted with a STOP, but not by
another interruption subroutine. When a subroutine is interrupted, it is not possible to get
into tool inspection mode.
