6.1 Device Master file (GSD)
In order to achieve a simple plug-and-play configuration for PROFIBUS, the
characteristic communication features for PROFIBUS devices were defined in the
form of an electronic device datasheet (device master file, GSD file).
The defined file format allows the projection system to easily read the device master
data of the PROFIBUS measuring system and automatically take it into account when
configuring the bus system.
The GSD file is a component of the measuring system and has the file name
● CEx-58:
"TR09AAAB.GSE"
(English).
● COx-58:
"TR0DAAAB.GSE"
(English).
The measuring system also includes two bitmap files with the names
"Traaab5n.bmp"
and
"Traaab5s.bmp"
, which show the measuring system in normal
operation as well as with a fault.
The files are on the Software/Support DVD:
Order number: 490-01001, Soft-No.: 490-00406.

6.2 PNO ID number
Every PROFIBUS slave and every Class 1 master must have an ID number. It is
required so that a master can identify the type of the connected device without
significant protocol overhead. The master compares the ID numbers of the devices
connected with the ID numbers of the projection data specified in the projection tool.
The transfer of utility data only starts once the correct device types have been
connected with the correct station addresses on the bus. This achieves a high level of
security against projection errors.
The measuring system has the PNO ID number AAAB (hex). This number is reserved
and is stored at the PNO.
