Subprograms and program section repeats | Calling an external NC program
Call with SEL PGM and CALL SELECTED PGM
The function SEL PGM allows you to select an external NC program
that you can separately call at a different position in the NC program.
The control runs the external NC program from the position at which
you called it in the NC program using CALL SELECTED PGM.
The SEL PGM function is also permitted with string parameters, so
that you can dynamically control program calls.
To select the NC program, proceed as follows:
Press the PGM CALL key
Press the SELECT PROGRAM soft key
The control starts the dialog for defining the
NC program to be called.
Press the SELECT FILE soft key
The control displays a selection window in which
you can select the NC program to be called.
Press the ENT key
If the called file is located in the same directory as the
file you are calling it from, you can also integrate the file
name without the path. The APPLY FILE NAME soft key
provided in the selection window of the SELECT FILE soft
key is available for this.
To call the selected NC program, proceed as follows:
Press the PGM CALL key
Press the CALL SELECTED PROGRAM soft key
The control uses CALL SELECTED PGM to call the
NC program that was selected last.
If an NC program that was called using CALL SELECTED
PGM is missing, then the control interrupts the execution
or simulation with an error message. In order to avoid
undesired interruptions during program run, you can use
the function FN 18 (ID10 NR110 and NR111) to check all
paths at the beginning of the program.

data", Page 306
