A fieldbus is an industrial network system for real-time distributed control. It is a way to connect instruments in a manufacturing plant. A fieldbus works on a network structure which typically allows daisy-chain, star, ring, branch, and tree network topologies. Previously, computers were connected using RS-232 … See more A fieldbus is a member of a family of industrial digital communication networks used for real-time distributed control. Fieldbus profiles are standardized by the International Electrotechnical Commission (IEC) as IEC … See more There were many competing technologies for fieldbuses and the original hope for one single unified communications mechanism has not been realized. This should not be unexpected since … See more Despite each technology sharing the generic name of fieldbus the various fieldbuses are not readily interchangeable. The differences between them are so profound that they cannot be easily connected to each other. To understand the differences … See more • Parallel Redundancy Protocol • Media Redundancy Protocol See more The most important motivation to use a fieldbus in a distributed control system is to reduce the cost for installation and maintenance of the installation without losing the high availability and reliability of the automation system. The goal is to use a two wire cable … See more The amount of cabling required is much lower in fieldbus than in 4–20 mA installations. This is because many devices share the same set of cables in a multi-dropped fashion rather than requiring a dedicated set of cables per device as in the case of 4–20 … See more As of 2008 , in process control systems, the market is dominated by Foundation Fieldbus and Profibus PA.
