Conditional Compilation - HEIDENHAIN iTNC 530 Technical Manual

8.2 Conditional Compilation

February 2002
Depending on the machine parameters, a PLC program can be conditionally
compiled on the iTNC. This allows you to select and deselect machine options
by entering the options in machine parameters. Therefore, only one PLC
program is necessary for all variants of machine options.
7 Enter the commands for the conditional compilation in the PLC program.
7 Create the Config. file.
7 In OEM.SYS, enter PLCCOMPCFG = followed by the path for the Config. file.
7 Enter the machine options in the machine parameters MP4000.x.
7 Reset the iTNC or recompile the PLC program.
Example:
OEM.SYS:
...
PLCCOMPCFG = PLC:\OEM\OEM.CFG
...
#if SWIVEL_HEAD = 3
...
#endif
#ifdef CHIP_CONVEYOR
...
#endif
#if STAR_DELTA = YES
...
#endif
#if TOOLCHANGER = 1
...
#endif
