Display update
The display is organized in such a way that the collected auxiliary functions are always displayed first, before
those that were managed by the PLC and before those that were managed by the NC. A collected auxiliary
function is marked as collected until it has been output from the NCK to the PLC. PLC-managed auxiliary
functions are retained until they are displaced by another auxiliary function. In the case of a reset, only the
collected auxiliary functions and the NC-managed auxiliary functions are deleted.
8.15.2 Querying system variables
Function
Auxiliary functions can be queried on a group-specific basis via system variables in the part program and via
synchronized actions:
$AC_AUXFU_... [<n>] = <value>
Auxiliary function is managed by the PLC and has been
directly applied by the PLC.

system variables Meaning
$AC_AUXFU_PREDEF_INDEX[<n>] <value>: Index of the last auxiliary function collected for
an auxiliary function group (search) or the last
predefined auxiliary function to be output
Typ
e:
INT
If no auxiliary function has been output yet for
the specified group or if the auxiliary function is
a user-defined auxiliary function, the variable
supplies the value "-1".
<n>: Group index (0 to 63)
Note:
A predefined auxiliary function can be uniquely identified via
this variable.
$AC_AUXFU_TYPE[<n>] <value>: Type of the last auxiliary function collected for
an auxiliary function group (search) or the last
auxiliary function to be output
Typ
e:
CHAR
<n>: Group index (0 to 63)
