Parameter: Address extension
The functionality of the address extension is not defined in user-specific auxiliary functions. It
is generally used to distinguish between auxiliary functions with the same "value".
Grouping together auxiliary functions
If all the auxiliary functions of the same type and value are assigned to the same auxiliary
function group, a value of "-1" must be entered for the "address extension" parameter.
Example:
All user-specific auxiliary functions with the value "= 8" are assigned to the tenth auxiliary
function group.
MD22000 $MC_AUXFU_ASSIGN_GROUP[ 1 ]
MD22010 $MC_AUXFU_ ASSIGN_TYPE[ 1 ]
MD22020 $MC_AUXFU_ ASSIGN_EXTENSION[ 1 ]
MD22030 $MC_AUXFU_ ASSIGN_VALUE[ 1 ]
Parameter: Value
The functionality of the "value" parameter is not defined in user-specific auxiliary functions.
The value is generally used to activate the corresponding PLC user function.
Grouping together auxiliary functions
If all the auxiliary functions of the same type and address extension are assigned to the
same auxiliary function group, a value of "-1" must be entered for the "value" parameter.
Example:
All user-specific auxiliary functions with the address extension "= 2" are assigned to the
eleventh auxiliary function group.
MD22000 $MC_AUXFU_ASSIGN_GROUP[ 2 ]
MD22010 $MC_AUXFU_ ASSIGN_TYPE[ 2 ]
MD22020 $MC_AUXFU_ ASSIGN_EXTENSION[ 2 ]
MD22030 $MC_AUXFU_ ASSIGN_VALUE[ 2 ]

Parameter: Output behavior
Function
The "output behavior" of user-defined auxiliary functions can be parameterized via the
machine data:
MD22035 $MC_AUXFU_ASSIGN_SPEC[ index ] (specification of output behavior)
For a description of the individual output parameters, see Section "Parameter: output
behavior" of the predefined auxiliary functions. The information given there can be applied
analogously to the output behavior of user-defined auxiliary functions.
