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 via "Downloads" and "Approvals".
10.2 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.
Ident 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. For VEGASON 62
the ID number is 0x0770(hex) and the GSD file "SN__0770.GSD". As an option to this manufactur-
er-specific GSD file, PNO provides also a general so-called profile-specific GSD file. For VEGASON
62 you have to use the general GSD file "PA139701.GSD". 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.
Note:
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.

II (IEC 61010-1)
When using the profile-specific GSD file, the PA-OUT value as well as
the temperature value are transmitted to the PLC (see block diagram
"Cyclical data traffic").
