18 Nibbling
Note
In the case of auxiliary functions for which no output behavior has been defined, the following
default output behavior is active:
● Bit 0 = 1: Output duration one OB1 cycle
● Bit 7 = 1: Output at block end

Parameterization

8.2.3.1

Group assignment

The handling of the auxiliary functions for a block search is defined using the group assignment
of an auxiliary function. The 168 auxiliary function groups available are subdivided into
predefined and user-definable groups:
Predefined groups:
User-defined groups:
Each predefined auxiliary function is assigned, as standard, to an auxiliary function group. For
most pre-defined auxiliary functions, this assignment can be changed using the following
machine data:
MD22040 $MC_AUXFU_PREDEF_GROUP[<n>] (group assignment of predefined auxiliary
functions)
If an auxiliary function is not assigned to any group, then a value of "0" should be entered into
the machine data.
For the pre-defined auxiliary functions with the following indices <n>, the group assignment
cannot be changed: 0, 1, 2, 3, 4, 22, 23, 24
Note
1. Auxiliary function group and block search
Auxiliary functions of the 1st auxiliary function group are, for a block search, only collected,
but not output.

Type, address extension and value

An auxiliary function is programmed via the type, address extension and value parameters
(see Section "Programming an auxiliary function (Page 412)").
