Appendix C. Foundation Fieldbus: Process Example
Overview
This section introduces a process example and several concepts used throughout various
discussions. It briefly introduces Foundation Fieldbus blocks and some of the essential block
concepts. The process example is a heat exchanger (Figure 49) with two control valves and three
measurement devices. The controls are configured in a cascade arrangement to illustrate
concepts of transfer between modes and states of the various levels of control.

Reference Model Process
The Heat Exchanger model, shown in Figure 49, is not a practical example but it does
incorporate elements that illustrate important SVI FF features. Each module has a device tag
used for SVI FF identification. The process consists of a vessel with a product vapor inflow that is
condensed and flows out as a liquid outflow. The tank level is controlled by an outflow control
valve, LV 201. The tank contents are chilled by coolant water. The temperature is controlled by a
temperature controller cascaded to a flow controller. The coolant flow is controlled by control
valve FV 101.
