1 Operation via FOUNDATION Fieldbus
1.1 Block model
In the FOUNDATION Fieldbus all the device parameters are categorised 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 (device block)
The Resource Block contains all the device-specific characteristics of the device.
• One or several Transducer Blocks (transmission block)
The Transducer Block contains all the measuring and device-specific parameters of
the device. The measuring principles, (e.g. flow, temperature, etc.), 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 realised depending on the arrangement and
connection of the individual function blocks. A field device may comprise further
function blocks e.g. several Analog Input function blocks if more than one process
variable is available from the field device.
Prosonic Flow 93 FOUNDATION Fieldbus has the following blocks:
• One Resource Block, see Page 89
• Six Transducer Blocks, see Page 100.
• Ten function blocks consisting of:
– Eight Analog Input function blocks, see Page 167.
– One Discrete Output, see Page 184.
– One PID function block (PID controller), see Page 197.
