H2: Auxiliary function outputs to PLC
8.13 Block-search response
Global list of auxiliary functions
At the end of SERUPRO, the auxiliary functions collected on a group-specific basis in the individual channels are
entered in a cross-channel (global) list with the channel number ($AN_AUXFU_LIST_CHANNO[<n>]) and group
index ($AN_AUXFU_LIST_GROUPINDEX[<n>]) according to their counter state ($AC_AUXFU_TICK[<n>,<m>]).
The two field variables $AN_AUXFU_LIST_CHANNO[<n>] and $AN_AUXFU_LIST_GROUPINDEX[<n>] from
the global list are writable and readable.
The index <n> has the following range of values: 0 ... MAXNUM_GROUPS * MAXNUM_CHANNELS - 1
The global list is structured on the basis of the sequence in which the search target was found. It is intended to be
used as a system proposal for auxiliary functions to be output in the following ASUB at the end of SERUPRO. If
an auxiliary function is not to be output, the corresponding group index is to be set to "0".
