For more detailed configuration instructions, please see brochure "FOUNDATION Fieldbus
solutions from ABB" (brochure no. 7592 FF). Further information is also available on the ABB
homepage at http://www.abb.com as well as on the homepage of the Fieldbus Foundation at

System integration
For integration into a process control system, a DD (device description) file, which contains the
device description, as well as a CFF (common file format) file are required. The CFF file is
required for segment engineering. Engineering can be performed online or offline.
The function blocks are described in the separate "FOUNDTAION Fieldbus interface description
for the meter" (part no. D184B093U23).
You can find both files, as well as the interface description, on the CD included in the scope of
supply (part no. D699D002U01). The CD can be ordered separately from ABB at any time free
of charge if required. The files can also be downloaded from http://www.fieldbus.org.
Block diagram
The diagram illustrates the function of the blocks available in the device. Communication tools
such as the NI Configurator, system tools or even a PLC supporting the appropriate function
can be used to access all blocks for parameterization acyclically.
