Fieldbus

Term from Automation Technology industry explained for recruiters

A Fieldbus is a communication system used in factories and industrial settings to connect machines, sensors, and control systems. Think of it like a special language that lets different pieces of industrial equipment talk to each other. Instead of having many separate wires connecting each device, Fieldbus uses a single cable network, similar to how your home internet connects multiple devices. Common types include Profibus, Modbus, and Foundation Fieldbus. This technology helps factories run more smoothly and efficiently by allowing equipment to share information and work together.
