9.10 Asynchronous subprograms (ASUBs), interrupt routines
● The signal states of the fast NC inputs can be read out via the NC/PLC interface (DB10).
● The transmission of the fast NC inputs to the interrupt signals can be disabled via the NC/
PLC interface (DB10).

For further information about PLC control of the rapid NC inputs (interrupt signals) see Section
"P3: Basic PLC program for SINUMERIK 840D sl (Page 821)".

Call of interrupt routines
During program mode
During program mode, i.e. in the AUTOMATIC or MDA mode, interrupt routines can always
be called.
Outside the program mode
Outside the program mode, interrupt routines can be called in the following modes, machine
functions and states:
● JOG, JOG REF
● MDA Teach In, MDA Teach In REF, MDA Teach In JOG, MDA REF, MDA JOG
● AUTOMATIC, program states "stopped", "ready"
● Axis state "Not referenced"
If an interrupt routine is started during JOG or JOG REF, the current action is aborted.
