When configuring a PROFIBUS–DP system where DP devices are to
be incorporated, which the configuring tool does not ”know” then the
new GSD files must be appropriately installed.
How is a new GSD file installed with SIMATIC S7?
New GSD files are installed in ”HW Config” as follows:
TOOLS ––> Installing new GSD file
All of the GSD files of DP devices of a plant/system are saved in the
project (e.g. for SIMATIC S7).
This means that it is always possible to edit this project using an additional
configuring/engineering tool, to which the project was transferred
– even if the GSD files for the DP devices to be used have still not
been installed on this device.
GSD files that are only saved in existing projects, but not in the general
GSD directory, are transferred into the generally valid GSD directory
using GSD import. This means that they can be used for additional new
projects.
4.4.3 Operating the slave with a third–party master
GSD file required
The master device data (GSD file) supplied with the equipment contains
all of the information/data that a DP master system requires in
order to incorporate SIMODRIVE POSMO A as DP standard slave in
its PROFIBUS configuration.
If the third–party master system allows a GSD file to be directly incorporated,
then the file for the DP slave can be directly copied into the
appropriate sub–directory.
