Approvals
Instruments with approvals can have different technical data depending on the version.
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.
The following table shows the instrument ID and the GSD names for the PROTRAC sensor series.
