H2: Auxiliary function outputs to PLC

8.13 Block-search response

Basic Functions

442 Function Manual, 09/2011, 6FC5397-0BP40-2BA0

Part program (section):

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

8.13.3 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)

8.13.4 Determining the output sequence

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[])

Program code

...

N10 ... M8

N20 ... M9

N30 ... M7

...

Input parameters:

VAR INT _NUM_IN: Number of relevant M commands

VAR INT _M_IN[]: Field of relevant M codes

VAR INT _EXT_IN[]: Field of relevant M address extensions

Output parameters:

VAR INT _NUM_OUT: Number of determined M codes

VAR INT _M_OUT[]: Field of determined M codes

VAR INT _EXT_OUT[]: Field of determined M address extensions
