Device Database File: GSD
Different PROFIBUS devices have different performance characteristics. These
characteristics differ with respect to functionality (for example, the number of I/O signals and
diagnostic messages) or bus parameters such as transmission speed and time monitoring.
These parameters vary for each device type and vendor and are usually documented in a
technical manual. To help you achieve a simple configuration of PROFIBUS, the
performance characteristics of a particular device are specified in an electronic data sheet
called a device database file, or GSD file. Configuration tools based on GSD files allow
simple integration of devices from different vendors in a single network.
The device database file provides a comprehensive description of the characteristics of a
device in a precisely defined format. These GSD files are prepared by the vendor for each
type of device and made available to the PROFIBUS user. The GSD file allows the
configuration system to read in the characteristics of a PROFIBUS device and use this
information when configuring the network.
The latest versions of the COM ET 200 (now called COM PROFIBUS) or STEP 7 software
include configuration files for the CPU 215. If your version of software does not include a
configuration file for the CPU 215, you can use a modem to access the PROFIBUS Bulletin
Board Service (BBS) and copy the GSD file for the CPU 215. When accessing the bulletin
board, respond to the prompts from the BBS to access the CPU 215 database, and copy the
file. This is a self-extracting file that provides the files required for PROFIBUS. Use the
following telephone numbers to access the BBS:
In North and South America: (423) 461-2751
File name to copy: S7215.EXE
In Europe: (49) (911) 73 79 72
File name to copy: W32150AX.200
You can also use the Internet to get the latest GSD file (device database file). The address
is: www.profibus.com
If you are using a non-Siemens master device, refer to the documentation provided by the
manufacturer on how to configure the master device by using the GSD file.
