Profibus
Profibus is a common communication system used in industrial and manufacturing settings to connect different machines and control equipment together. Think of it like a special language that allows various industrial devices (like motors, sensors, and control panels) to talk to each other. It's particularly popular in factories, power plants, and other industrial facilities. When you see this on a resume, it usually means the candidate has experience working with automated industrial systems. Similar systems include Modbus and DeviceNet. Companies use Profibus because it's reliable and widely supported by major manufacturers of industrial equipment.
