Figure 7-3 Interconnection of the receive words
The telegrams use - with the exception of telegram 999 (free interconnection) - the word-by-
word transfer of send and receive data (r2050/p2051).
If you require an individual telegram for your application (e.g. for transferring double words),
you can adjust one of the predefined telegrams via parameters p0922 and p2079. For
details, please refer to the List Manual, function diagrams 2420 and 2472.
