What is Fieldbus in Industrial Communication Networks?

Fieldbus can be defined as a digital, serial, multidrop, data bus for communication with industrial control and instrumentation devices such as sensors, transducers/transmitters, actuators, local controllers, etc.

Alternatively, Fieldbus can be defined as a digital, two-way, multidrop communication link among intelligent or smart 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.

Fieldbus

There exists many different fieldbuses (digital communication standards) designed to interconnect instruments. Some of these fieldbuses include:

  • Foundation fieldbus
  • Modbus
  • HART
  • CANbus
  • Profibus PA
  • Profibus DP
  • Profibus FMS
  • ControlNET
  • AS-I
  • BACnet
  • DeviceNet
  • LonWorks
