4.2 Description of the Foundation Fieldbus block system
The Foundation Fieldbus is a Local Area Network (LAN) for connecting field devices like sensors
and actuators. One of the main benefits of Foundation Fieldbus is line saving in comparison to
the traditional 4...20 mA technology.
The different device functions are implemented in a block-based scheme within a user
application. In this block scheme, a distinction is made between the Resource Block, Transducer
Block and Function Block.
