Detailed Description
2.2 User-defined auxiliary functions
Auxiliary Function Output to PLC (H2)
2-12 Function Manual, 08/2005 Edition, 6FC5397-0BP10-0BA0
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
One feature of user-specific auxiliary functions is that the parameter "Type" must always be
H. They refer only 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 functions per channel can be parameterized
via:
MD11100 $MN_AUXFU_MAXNUM_GROUP_ASSIGN (maximum number of user-definable
auxiliary functions)
2.2.3 Extension of predefined auxiliary functions
Function
Because there is only one set of machine data for the predefined auxiliary functions, they
can only ever be used to address one spindle of the channel. To address further spindles,
user-defined auxiliary functions must be parameterized to supplement the predefined
auxiliary functions.
The extension of predefined auxiliary functions refers only to the parameter: "Address
extension". The number of the spindle that the auxiliary function refers to is entered in the
"Address extension" parameter.
The relevant predefined auxiliary functions can be extended for the following system
functions.
