For additional information, see the separate interface description.
System integration
In conjunction with the DTM (Device Type Manager) available for the
device, communication (configuration, parameterization) can occur
with the corresponding framework applications according to FDT 1.21
(DAT200 Asset Vision Basic).
Other tool/system integrations (e.g., Emerson AMS/Siemens PCS7)
are available upon request.
A free of charge version of the DAT200 Asset Vision Basic framework
application for HART® or PROFIBUS is available upon request.
The required DTMs are contained on the DAT200 Asset Vision Basic
DVD or in the DTM Library.
They can also be downloaded from www.abb.com/flow.
PROFIBUS PA protocol
The interface conforms to profile 3.01 (PROFIBUS standard, EN
50170, DIN 19245 [PRO91]).
PROFIBUS PA ID no.: 0x3430

Bus topology
• Tree and/or line structure
• Bus termination: passive at both ends of the main bus line (RC
element R = 100
Ω , C = 1 µF)
Voltage / current consumption
• Average current consumption: 10 mA
• In the event of an error, the integrated FDE function (=Fault
Disconnection Electronic) integrated in the device is ensures that
the current consumption can rise to a maximum of 13 mA.
• The upper current limit is restricted electronically.
• The voltage on the bus line must lie in the range of 9 ... 32 V DC.
For additional information, see the separate interface description.
System integration
ABB provides three different GSD files (equipment master data) which
can be integrated in the system.
Users decide at system integration whether to install the full range of
functions or only part.
The change-over is done using the “ID-number selector” parameter.
ID number 0x9700, GSD file name: PA139700.gsd
ID number 0x9740, GSD file name: PA139740.gsd
ID number 0x3430, GSD file name: ABB_3430.gsd
The interface description appears on the CD included in the scope of
supply.
The GSD files can also be downloaded from www.abb.com/flow.
The files required for operation can be downloaded from
www.profibus.com.
