A device description file (GSD file) is used for the formal description of a PROFIBUS-DP slave.
The PROFIBUS project planning tools require the information from the GSD to allow the
master and the PLC system to exchange data with the slave.
For example, the GSD contains information about the supported transfer rates, various bus
parameters, whether Freeze/Sync is supported and other features of the device. The most
important information is the data width offered by the slave, i.e., how many bytes of inputs and
outputs is has.
In addition, the GSD file contains references to image files (bitmaps) for the symbolic dis-
play of the module in the regular and diagnostic case.
Depending on the diagnostics tool used, the images must be copied into a specific direc-
tory before its use or the complete path including bitmaps must be specified in the GSD.
Please read the description of the project planning/diagnostics tool used. The keywords in the
GSD file are <Bitmap_Device> and <Bitmap_Diag>.
The GSD files contain standard error texts for the extended PROFIBUS diagnostics. The
configuration tool automatically displays these diagnostics texts in case of a malfunction. This
allows the user to recognize the reason for a malfunction without the PLC having to perform
the error decoding.
The current GSD files of the Wieland devices can be found on the Internet under http:\\

The import of the GSD file in SIMATIC STEP7 is described below.
NOTE
The procedure described here and the images shown refer to SIMATIC STEP7 version
5.1. The current documentation for the STEP7 project planning software applies in each
case.
