2.2 Userdefined auxiliary functions
2.2.1 User-specific and extended predefined auxiliary functions
Function
There are two uses for user-defined auxiliary functions:
• Extension of predefined auxiliary functions
• User-specific auxiliary functions
Extension of predefined auxiliary functions
Extension of predefined auxiliary functions refers to the parameter: "Address extension". The
address extension defines the number of the spindle to which the auxiliary function applies.
User-specific auxiliary functions
User-specific auxiliary functions relate exclusively to user functions. User-specific auxiliary
functions do not activate system functions.
2.2.2 Maximum number of user-defined auxiliary functions
Maximum number
The maximum number of user-defined auxiliary function per channel can be parameterized
via the machine data:
MD11100 $MN_AUXFU_MAXNUM_GROUP_ASSIGN (maximum number of user-definable
auxiliary functions)
Basic logic functions: Auxiliary Function Output to PLC (H2)
