10.2 Information on Proﬁbus PA

Instrument

master ﬁle

The instrument master ﬁle (GSD) contains t he 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 automatically

when the GSD ﬁle is integrated. The bitmap ﬁle is used for symbolic indication of the PA instrument 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 VEGABAR 64

the ID number is 0 x 076F(hex) and the GSD ﬁle BR__076F.GSD. As an option to this manufacturer-

speciﬁc GSD ﬁle, PNO provides also a general so-called proﬁle-speciﬁc GSD ﬁle. For VEGABAR 64

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:

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").

Cyclical data traﬃc

The master class 1 (e.g. PLC) cyclically reads out measured values from the sensor during operation.

The below block diagram below shows which data can be accessed by the PLC.
