(also industrial fieldbus)

Fieldbus definition

Fieldbus is an industrial network system for real-time distributed control. It is a standard for data communication in automation technology and links industrial plant equipment like sensors, actuators, and controllers. In addition, Fieldbus reduces the amount of wiring required compared to traditional point-to-point wiring methods, streamlining system setup, maintenance, and scaling.

Fieldbus examples

  • Manufacturing automation: Fieldbus networks are common in manufacturing automation, where they connect different plant machinery for coordinated control.
  • Process control: In industries such as oil and gas, fieldbus systems integrate control and instrumentation to enable efficient process management.

Advantages and disadvantages of fieldbus


  • Efficiency: Fieldbus systems reduce the need for extensive wiring, resulting in cost and labor savings.
  • Integration: Fieldbus networks allow the integration of equipment from different manufacturers, facilitating interoperability.
  • Diagnostic capabilities: They offer advanced diagnostic information from field devices, improving fault detection and maintenance.


  • Complexity: Implementing and managing fieldbus systems can be complex due to the diverse range of standards and protocols.
  • Training: The requirement for specialized knowledge and training to maintain fieldbus systems could be a constraint.

Using fieldbus

  • Ensure proper training for staff to troubleshoot and maintain the fieldbus network.
  • Use a secure and robust networking infrastructure, considering the use of a VPN for enhanced security, especially for remote access and control.
