Parameter: Type
The name of an auxiliary function is defined via the "Type". Only the following names are
permitted for user-defined auxiliary functions:
• User-specific auxiliary functions
• Extension of predefined auxiliary functions
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
To assign all auxiliary functions of the same type and value to the same auxiliary function
group, a value "–1" must be entered for parameter "Address extension".
Example
All user-specific auxiliary functions with the value = 8 are assigned to auxiliary function group
10.

Parameter: Value
The functionality of parameter: "Value" is not defined in user-specific. auxiliary functions. The
value is generally used to activate the corresponding PLC user function.
Grouping together auxiliary functions
To assign all auxiliary functions of the same type and address extension to the same
auxiliary function group, a value "–1" must be entered for parameter "Value".
Example
All user-specific auxiliary functions with the address extension = 2 are assigned to auxiliary
function group 11.
