$AC_AUXFU_VALUE[<n>]
or M function specific:
$AC_AUXFU_M_VALUE[<n>]
$AC_AUXFU_SPEC[<n>]
$AC_AUXFU_STATE[<n>]
or M function specific:
$AC_AUXFU_M_STATE[<n>]
Example
All M-auxiliary functions of the 1st group will be stored in the order they are output
id=1 every $AC_AUXFU_M_STATE[0]==2 do $AC_FIFO[0,0]=
$AC_AUXFU_M_VALUE[0]

H2: Auxiliary function outputs to PLC
Meaning
<value>: Value of the last auxiliary function collected for
an auxiliary function group (search) or the last
auxiliary function to be output
Type REAL
:
<n>: Group index (0 to 63)
Value: Bit-encoded output behavior according to
MD22080/MD22035 (or QU programming) of the
last auxiliary function collected for an auxiliary
function group (search) or the last auxiliary func‐
tion to be output
Type INT
:
<n>: Group index (0 to 63)
Note:
This variable can be used to determine whether the auxiliary
function should be output with a fast acknowledgement.
<value>: Output state of the last auxiliary function collec‐
ted for an auxiliary function group (search) or the
last auxiliary function to be output
Type:
Value range:
0: No auxiliary function
1: M-auxiliary function was collected via a
search
2: M-auxiliary function has been output to the
PLC
3: M-auxiliary function has been output to the
PLC and the transport acknowledgement
has taken place
4: M-auxiliary function is managed by the PLC
and has been applied by the PLC
5: M-auxiliary function is managed by the PLC,
and the function acknowledgement has tak‐
en place
<n>: Group index (0 to 63)
