5.2 Device description file (XML)
In order to achieve a simple plug-and-play configuration for PROFINET, the
characteristic communication features for PROFINET devices were defined in the form
of an electronic device datasheet, GSDML file:
“
G

S
tation
D

M

L
anguage”. In contrast to the PROFIBUS-DP
system the GSDML file is multilingual and contains several device variants in one file.
The defined file format allows the projection system to easily read the device master
data of the PROFINET measuring system and automatically take it into account when
configuring the bus system.
The GSDML file and the corresponding bitmap file are components of the measuring
system.

5.3 Device identification
Each PROFINET IO-Device possesses a device identification. It consists of a firm
identification, the Vendor-ID, and a manufacturer-specific part, the Device-ID. The
Vendor-ID is assigned by the PNO. For TR-Electronic the Vendor-ID contains the
value 0x0153, the Device-ID has the value 0x0301.
When the system boots up the projected device identification is examined. In this way
errors in the project engineering can be recognized.
