For that reason the associated approval documents of these instruments must be carefully noted.
They are part of the delivery or can be downloaded under www.vega.com and "VEGA Tools" as
well as under "Downloads" and "Approvals".
11.2 Communication Profibus PA
Instrument master file
The instrument master file (GSD) contains the characteristic data of the Profibus PA instrument.
These data are, e.g. the permissible transmission rates as well as information on diagnostics values
and the format of the measured value outputted by the PA instrument.
A bitmap file is also provided for the Profibus network planning tool. This file is installed automati-
cally when the GSD file is integrated. The bitmap file is used for symbolic indication of the PA instru-
ment in the configuration tool.
ID number
Each Profibus instrument gets an unambiguous ident number (ID number) from the Profibus user
organisation (PNO). This ID number is also included in the name of the GSD file. Optionally to this
manufacturer-specific GSD file, PNO provides also a general so-called profile-specific GSD file. If
the general GSD file is used, the sensor must be set to the profile-specific ident number via the DTM
software. By default, the sensor operates with the manufacturer-specific ID number. When using the
instruments on a segment coupler SK-2 or SK-3, no special GSD files are required.

Cyclical data traffic
The master class 1 (e.g. PLC) cyclically reads out measured values from the sensor during opera-
tion. The below block diagram below shows which data can be accessed by the PLC.
