Examples
● C a lling an internal subroutine
The "Main.mpf" main program stored on the USB memory stick is selected for execution:
N10 G4 F0.5
N20 MSG("CALL Milling")
N30 CALL "//NC:/MPF.DIR/BOHRUNG.SPF"
N40 M30
The "BOHRUNG.SPF" subprogram stored in the NC directory is to be reloaded:
N10 G01 X10 Y20 Z30 F1000
N20 G91 X10 Y10 Z10
N30 M30
● C a lling an external subroutine
The "Main.mpf" main program stored in the NC directory is selected for execution:
N10 G0 X10 Y10
N20 EXTCALL ("USB:\BOHRUNG.SPF") *
N30 G0 X20 Y20
N40 M30
* If you have set SD 42700 as "USB:\", you only need to enter EXTCALL ("BOHRUNG.SPF") alternatively.
The "BOHRUNG.SPF" subprogram stored on the USB memory stick is to be reloaded:
N10 G01 X10 Y20 Z30 F1000

Timers and workpiece counters

11.16.1 Runtime timer
Fu n ctionality
The timers are prepared as system variables ($A...) that can be used for monitoring the technological processes in the
program or only in the display.
These timers are read-only. There are timers that are always active. Others can be deactivated via machine data.
Ti mers that are always active
● $ AN_SETUP_TIME
Time since the last control power up with default values (in minutes)
It is automatically reset in the case of a system power-up with default values.
● $ AN_POWERON_TIME
Time since the last control power up (in minutes)
It is reset to zero automatically after each power-up of the control system.
