FOUNDATION Fieldbus technology

The FOUNDATION Fieldbus (FF) is a purely digital, serial communication system that
connects fieldbus devices (sensors, actors), automation and process control systems
with each other. As a local communications network (LAN) for field devices the FF was
primarily designed for the requirements of process technology. The FF thus forms the
basic network throughout the hierarchy of a communication system.

The following figure shows two typical examples of a FOUNDATION Fieldbus network
with the associated components.
