Why can’t I parameterize my ET200M modules if I want to configure
the station via GSD files?
You have downloaded the GSD file of your
ET200M station from Entry ID: 113498 and have integrated them
into STEP 7 according to the instructions in Entry ID:
When you open the configuration dialog of a module, then the tab
required for configuring the module is not available.

On the download pages of Customer Support there are often
various GSD files (with fixed and free configuration) offered for
the same slave types. The reasons for this are:
- GSD files are not only used by STEP 7, but also by other
configuration tools. These tools and also older versions of STEP 7
and COM PROFIBUS do not support import of GSD files larger than 64
Kbytes - see Entry ID: 11869047.
- GSD files have to accommodate different PROFIBUS standards (DP
- Certain DP masters do not support any complex configuration
messages or any special ID formats.
Therefore, when downloading GSD files, you should make sure that
the file you want actually supports parameterization of the
modules. You can tell this easily by the size of the GSD file.
Small files (approx. 5 Kbytes) generally do not support assignment
of module parameters.

Therefore, on the download side, you should check to see whether
there are other GSD files available for the same slave which are
larger and you should then always use the GSD file that is
The function range of a slave depends not only on the configuration
data, but also on the properties of the master.
