Fieldbus
A general term for industrial digital networks connecting controllers and field devices.
IN ONE SENTENCE
It replaces large amounts of individual point-to-point signal wiring with shared communication.
In normal English
PROFIBUS, DeviceNet, CANopen and Foundation Fieldbus are examples; each has its own rules and ecosystem.
Why would I use it?
Use the term as a category rather than assuming all fieldbuses are compatible.
