8.13 Block-search response

Part program (section):

Program code

During the block search, the auxiliary function M9 is collected for groups 5 and 6.

Scan of the collected M auxiliary functions:

M function of the fifth group: $AC_AUXFU_M_VALUE [4] = 7

M function of the sixth group: $AC_AUXFU_M_VALUE [5] = 9

Time stamp of the active M auxiliary function

When outputting collected auxiliary functions following a block search, attention must be paid to the sequence

during collecting. For this reason, each group is assigned a time stamp which can be queried on a group-specific

basis by way of the system variable below:

$AC_AUXFU_M_TICK[<n>] (time stamp of the active M auxiliary function)

The following predefined procedure is provided to simplify the process of determining the output sequence of M

auxiliary functions for the programmer:

AUXFUMSEQ(VAR INT _NUM_IN, VAR INT _M_IN[], VAR INT _EXT_IN[], VAR INT _NUM_OUT,

VAR INT _M_OUT[], VAR INT _EXT_OUT[])

Input parameters:

VAR INT _NUM_IN:

VAR INT _M_IN[]:

VAR INT _EXT_IN[]:

Output parameters:

VAR INT _NUM_OUT:

VAR INT _M_OUT[]:

VAR INT _EXT_OUT[]:
