Programming communications modules
B.1
Programming the communication modules on
PROFIBUS/PROFINET
For whom is this Appendix intended?
This section does not need to be considered by SIMATIC users. It is intended particularly for
programmers of PCs and third-party PLCs. The information enables the programmer to
develop customized function blocks or drivers for the communication module.
Note
Some signals in this appendix have the same meaning as the variables in section
"Parameter data block (Page 19)". In order to distinguish between them, an underscore "_" is
appended to the relevant signals (e.g. ANZ_MDS_present_).
