6 Device introduction
Fieldbus Foundation communication
protocol
Foundation Fieldbus™ is an all-digital, serial, two-way
communication system that serves as a Local Area Network
(LAN) for factory/plant instrumentation and control devices.
IMPORTANT
Further information on FOUNDATION Fieldbus can be found
from the Fieldcomm Group organization website www.
Fieldcommgroup.org, from the ABB website www.abb.com/
fieldbus and/or from standards IEC 61158, IEC 61784, EN
50170/DIN 19245 and EN 50020 (FISCO model).

FF device structure
The Foundation Fieldbus devices can be divided into two parts
under the point of view of technical competence who must take
care of its configuration and use.
• The Device Application Process (DAP) is device specific and
stays with the device wherever it is used.
• The Control Application Process (CAP) is configured for the
specific plant location and may be spread over multiple
devices.
Communication between the DAP and CAP takes place using
channels. Each I/O function block in the CAP has exclusive use
of exactly one channel. A channel may be bi-directional and it
may have multiple values.
Device Application Process (DAP)
The DAP is used primarily by the instrumentation technician or
maintenance personnel for configuring I/O when the
instrument is going to be installed in the plant and/or during
maintenance operations and for this reason mainly focused on
the Resource Block and Transducer Blocks of the device.
Control Application Process (CAP)
The CAP is used by the control engineer for configuring the
plant control strategy and for this reason mainly focused on the
Function Blocks of the device.
IMPORTANT
For convenience, all the device parameters mentioned in
this document are written with the prefix indicating the
block into where they are mapped:
• RB_ = Resource Block
• PRTB_ = Pressure Transducer Block
• ADTB_ = Advanced Diagnostic Transducer Block
• HMI_ = HMI Transducer Block
• AIx _ = Analog Input Function Blocks where the x is the
number of the AI (1, 2, 3).

For all the complete details about the device parameters
and their block mapping refer to the dedicated section of
