A FOUNDATION Fieldbus device has the following block types:
One Resource Block
The Resource Block contains all the hardware specific characteristics.
One or more Transducer Blocks
The Transducer Block contains all the data and device-specific parameters to link the
device to the process data (sensor or actuator).
One or more Function Blocks
Function Blocks provide generally useable automation functions.
There are various different types of Function Block, e.g. Analog Input Function Block,
Analog Output Function Block, PID Function Block and other input, output and processing
blocks.
Each of these Function Blocks can be used for processing various application functions in
