Brochure "PROFIBUS - Solutions from ABB" (no. 30/FB-10) contains more detailed information
about configuration. Accessories such as terminal blocks, connectors, and cables are listed in
data sheet 10/63-6.44. Supplementary information also appears both on the ABB homepage at
System integration
The use of the PROFIBUS PA Profile B, V3.0, means that the meters are not only interoperable
(in other words, devices from different manufacturers can be physically connected to one and
the same bus and communicate on it), they are also interchangeable (in other words, devices
from different manufacturers can be interchanged without having to modify the configuration in
the process control system).
To support interchangeability, ABB provides three different GSD (generic station description)
files for system integration. During system integration, users decide whether to install the full
range of functions or only part. Devices are interchanged using the ID number selector
parameter, which can only be modified on an acyclic basis. The following table describes the
available GSD files:
Number and type of
function blocks

1 x Al; 1 x TOT 0 x 9740 PA 139740.gsd
2 x AI; 1 x TOT
and all manufacturer-
specific parameters

The GSD files appear on the CD included in the scope of supply. The standard GSD files
"PA1397xx.gsd" are available for download from the PNO homepage at
