14.3 Executing a program
When you select a program for execution, the control switches automatically to the "Machine"
operating area.
Program selection
Select the workpieces (WPD), main programs (MPF) or subprograms (SPF) by placing the
cursor on the desired program or workpiece.
For workpieces, the workpiece directory must contain a program with the same name. This
program is automatically selected for execution (e.g. when you select the workpiece
SHAFT.WPD, the main program SHAFT.MPF is automatically selected).
If an INI file of the same name exists (e.g. SHAFT.INI), it will be executed once at the first part
program start after selection of the part program. Any additional INI files are executed in
accordance with machine data MD11280 $MN_WPD_INI_MODE.
MD11280 $MN_WPD_INI_MODE=0:
The INI file with the same name as the selected workpiece is executed. For example, when you
select SHAFT1.MPF, the SHAFT1.INI file is executed upon <CYCLE START>.
MD11280 $MN_WPD_INI_MODE=1:
All files of type SEA, GUD, RPA, UFR, PRO, TOA, TMA and CEC which have the same name
as the selected main program are executed in the specified sequence. The main programs
stored in a workpiece directory can be selected and processed by several channels.
