Approvals
Instruments with approvals can have different technical specifications depending on the version.
For that reason the associated approval documents of these instruments have to be carefully
noted. They are part of the delivery or can be downloaded under www.vega.com
via "
VEGA Tools
"
and "
Instrument search
" as well as in the download area.
13.2 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 in ad
-
dition to this manufacturer-specific GSD file, PNO also provides 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.
