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 PROFIBUS or STEP 7 software include
configuration files for the EM 277 PROFIBUS-DP Module. If your version of
software does not include a configuration file for the EM 277, you can access the
latest GSD file (SIEM089D.GSD) at website 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.
