The Basics

The open, non-proprietary Foundation architecture provides a communications protocol for control and instrumentation systems in which each device has its' own "intelligence" and communicates via an all-digital, serial, two-way communications system. To learn more about the advantages of an all-digital FOUNDATION fieldbus infrastructure, read the brochure to the left.

Benefits of FOUNDATION Technology

Real-time closed loop control completely digital end-to-end, from sensor to actuator  More current for more powerful two-wire loop powered devices like radar level transmitters, multi-channel temperature transmitters, and more diagnostics etc. 
Balanced (non-grounded) signal with high amplitude for noise immunity
Intelligent discrete devices like two-wire on/off valves
Multiple devices on the same pair of wires reducing cable, tray, junction boxes and associated labor
Multiple signals (per device) on the same pair of wires dramatically reducing cable, tray, junction boxes and associated labor
Dramatic reduction of I/O cards reducing system footprint and weight
Elimination of I/O card selection simplifying engineering
Elimination of safety barrier selection simplifying engineering
Elimination of signal marshalling simplifying engineering
Easy addition of devices
Easy addition of signals in devices
Easy to change design to other device type: e.g. on/off valve to control valve or MOV
Time synchronized control
Fast control response period
No 4-20 mA range mismatch
No 4-20 mA current calibration skew
Signal distortion detected
Measurement over full sensor limit (no 4-20 mA range)
No 4-20 mA five point loop test
Real-time PV validity indication
Position feedback on every valve
Multi-channel temperature transmitters
Advanced device diagnostics
Centralized firmware upgrade


Foundation H1 is intended primarily for process control, field-level interface and device integration. Running at 31.25 kbit/s, the technology interconnects devices such as transmitters and actuators on a field network. H1 is designed to operate on existing twisted pair instrument cabling with power and signal on the same wire. Fiber optic media is optional. It also supports Intrinsic Safety (IS) applications (Read More).

High Speed Ethernet (HSE) is ideally suited for use as a control backbone. Running at 100 Mbit/s, the technology is designed for device, subsystem and enterprise integration. It supports the entire range of fieldbus capabilities, including standard function blocks and Device Descriptions (DDs), as well as application-specific Flexible Function Blocks (FFBs) for advanced process and discrete/hybrid/batch applications (Read More).

Function Block Model
A unique characteristic of the Foundation architecture ensuring device interoperability is its use of a fully specified, standard User Layer based on "Blocks" and Device Descriptions (DDs). The User Layer defines a Function Block Application Process (FBAP) using Resource Blocks, Function Blocks, Transducer Blocks, System Management, Network Management and DD technology (Read More).

Electronic Device Description Language (EDDL) is a programming language used to create Device Descriptions (DDs) to describe the attributes of field devices in an Operating System (OS) and Human Machine Interface (HMI)-neutral environment. EDDL is used to create DDs for functions such as generic digital and analog input/output modules, HMI displays and transmitters, on-off and regulating valves, and closed-loop controller diagnostics (Read More).

The Fieldbus Foundation's Safety Instrumented Functions (SIF) program is delivering the benefits of open, interoperable fieldbus technology to the industrial safety market. The initiative is supported by a "who's who" of control industry leaders (Read More).


The Fieldbus Foundation's Remote Operations Management (ROM) program promises to change the world of remote operations management for pipeline supervisory control and data acquisition (SCADA), tank farms and terminals, offshore platforms, and water/wastewater facilities (Read More).

Controls suppliers and end users alike need to understand today's fieldbus terminology. The technology includes many new terms describing advanced functionalities for plant floor to boardroom data integration (Read More).

Field Device Integration, or FDI for short, is simply the rationalization of benefits of EDDL and FDT/DTM technologies. End users across the world recognized the benefits of both (Read More).
