2.1.1 Predefined auxiliary functions
Function
Predefined auxiliary functions are auxiliary functions for activating system functions. The
assignment of predefined auxiliary functions to system function cannot be changed.
During execution of a predefined auxiliary function, the corresponding system function is
activated and the auxiliary functions are output to the NC/PLC interface.
Definition of a predefined auxiliary function
The parameters of a predefined auxiliary function are stored in machine data and can be
changed in some cases. All parameters of an auxiliary function have the same index.
• MD22040 $MC_AUXFU_PREDEF_GROUP[ Index ] (Pre-defined auxiliary function
groups)
• MD22050 $MC_AUXFU_PREDEF_TYPE[ Index ] (Pre-defined auxiliary function type)
• MD22060 $MC_AUXFU_PREDEF_EXTENSION[ Index ] (Pre-defined auxiliary function
extension)
• MD22070 $MC_AUXFU_PREDEF_VALUE[ Index ] (Pre-defined auxiliary function value)
• MD22080 $MC_AUXFU_PREDEF_SPEC[ Index ] (output specification)
