Example
Extension of the predefined auxiliary function for the system function "spindle right" for the
second and third spindle of the channel.
Auxiliary function "spindle right" for the second spindle of the channel:
MD22010 $MC_AUXFU_ASSIGN_TYPE[ n ] = "M"
MD22020 $MC_AUXFU_ASSIGN_EXTENSION[ n ] = 2
MD22030 $MC_AUXFU_ ASSIGN_VALUE[ n ] = 3
Auxiliary function "spindle right" for the third spindle of the channel:
MD22010 $MC_AUXFU_ ASSIGN_TYPE[ m ] = "M"
MD22020 $MC_AUXFU_ASSIGN_EXTENSION[ m ] = 3
MD22030 $MC_AUXFU_ ASSIGN_VALUE[ m ] = 3
2.2.4 User-specific auxiliary functions
Function
User-specific auxiliary functions have the following characteristics:
• User-specific auxiliary functions only activate user functions.
• No system functions can be activated by user-specific auxiliary functions.
• A user-specific auxiliary function is output to the PLC according to the parameterized
output behavior.
• The functionality of a user-specific auxiliary function is implemented by the machine
manufacturer/user in the PLC user program.
