18.2 INTERRUPTION TYPE CUSTOM MACRO
When a program is being executed, another program can be called by
inputting an interrupt signal (UINT) from the machine. This function is
referred to as an interruption type custom macro function. Program an
interrupt command in the following format:
M96Pxxxxxxxx ; Enables custom macro interrupt
M97; Disables custom macro interrupt
Use of the interruption type custom macro function allows the user to
call a program during execution of an arbitrary block of another
program. This allows programs to be operated to match situations
which vary from time to time.
(1) When a tool abnormality is detected, processing to handle the
abnormality is started by an external signal.
(2) A sequence of machining operations is interrupted by another
machining operation without the cancellation of the current
operation.
(3) At regular intervals, information on current machining is read.
Listed above are examples like adaptive control applications of
the interruption type custom macro function.
