1.1 Block model
In the FOUNDATION Fieldbus all the device parameters are categorized according to their
functional properties and task and are generally assigned to three different blocks. A block may be
regarded as a container in which parameters and the associated functionalities are contained. A
FOUNDATION Fieldbus device has the following block types:
•A Resource Block
The Resource Block contains all the device-specific characteristics of the device.
• One or more Transducer Blocks (transmission blocks)
The Transducer Block contains all the measuring technology and device-specific parameters of
the device. The measurement principles (e.g. flow, temperature) are depicted in the Transducer
Blocks in accordance with the FOUNDATION Fieldbus specification.
• One or more function blocks
Function blocks contain the automation functions of the device. We distinguish
between different function blocks, e.g. Analog Input function block, Analog Output function
block, PID function block (PID controller), etc. Each of these function blocks is used to process
different application functions.
Different automation tasks can be realized depending on the arrangement and connection of the
individual blocks. In addition to these blocks, a field device may have any number of further blocks,
e.g. several Analog Input function blocks if more than one process variable is available from the field
device.
The Promass 83 FOUNDATION Fieldbus has the following blocks:
•One Resource Block
• Seven Transducer Blocks
• Fourteen function blocks consisting of:
– Eight Analog Input function blocks
– One Discrete Output function block
– One PID function block
– One Arithmetic function block
– One Input Selector function block
– One Signal Characterizer function block
– One Integrator function block
