Fieldbus 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
LMT100/200 FF are implementing the following Blocks:
– 1 Standard Resource Block
– 5 Analog Input Function Blocks
– 3 PID Function Block
– 1 Arithmetic Function Block
– 1 Control Selector Function Block
– 1 Transducer Block with Linearization Table
– 1 HMI Transducer Block
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
