Function of an interrupt routine

Note
The terms "asynchronous subprogram (ASUB)" and "interrupt routine" are used
interchangeably in the description below to refer to the same functionality.
Function
A typical example should clarify the function of an interrupt routine:
The tool breaks during machining. This triggers a signal that stops the current machining
process and simultaneously starts a subprogram – the so-called interrupt routine. The
interrupt routine contains all the statements, which are to be executed in this case.
