Approvals

Instruments with approvals can have dierent technical data 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 "serial number search" as well as via "Downloads" and "Approvals".

10.2 InformationonProbusPA

Instrumentmasterle

The instrument master le (GSD) contains the characteristic data of the Probus 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 le is also provided for the Probus network planning tool. This le is installed automati-

cally when the GSD le is integrated. The bitmap le is used for symbolic indication of the PA instru-

ment in the conguration tool.

Ident number

Each Probus instrument gets an unambiguous ident number (ID number) from the Probus user

organisation (PNO). This ID number is also included in the name of the GSD le. For VEGABAR 52

the ID number is 0x076F(hex) and the GSD le BR__076F.GSD. As an option to this manufactur-

er-specic GSD le, PNO provides also a general so-called prole-specic GSD le. For VEGABAR

52 you have to use the general GSD le PA139701.GSD. If the general GSD le is used, the sensor

must be set to the prole-specic ident number via the DTM software. By default, the sensor oper-

ates with the manufacturer-specic ID number.

Note:

When using the prole-specic GSD le, the PA-OUT value as well as the temperature

value are transmitted to the PLC (see block diagram "Cyclical data trac").

Cyclicaldatatrac

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.

17)

Instruments with gauge pressure measuring ranges cannot detect the ambient pressure when submerged, e.g.

in water. This can lead to falsication of the measured value.

18)

Only with instruments with absolute pressure ranges.
