A Fieldbus is a digital, two-way, multi-drop communication link among intelligent measurement and control devices. It serves as a Local Area Network (LAN) for advanced process control, remote input/output and high speed factory automation applications.
a standard for digital communications between field devices and their control systems. Devices include flow, temperature, and pressure sensors and actuators of valves and motors.
A communications protocol sometimes used in SCADA systems.
a communication system for exchanging information between field devices, sensors and actuators
All-digital communication network used to connect process instrumentation and control systems. Designed to replace systems based on 4-20 mA analog signals with bi-directional, multivariable data communication capability.
communication line between instruments and controllers.
A high speed serial interfaces used to communicate between devices.
Generic term applied to an open or generic network of automation devices used for factory automation or process control; industrial network system for real-time distributed control.
Fieldbus is a generic term used to describe a common communications protocol for control systems and/or field instruments. Although some standard forms have been agreed for instruments, the DCS industry as a whole has so far no agreed fieldbus. Often, the Foundation Fieldbus is referred to simply as the Fieldbus.
A Fieldbus is an industrial network system for real-time distributed control.
