EtherNet/IP
EtherNet/IP is a communication system used in modern factories and industrial settings to connect machines, control systems, and devices. Think of it as a specialized industrial version of the internet that allows manufacturing equipment to talk to each other. It combines regular Ethernet technology (like what's used in offices) with industrial protocols, making it easier for companies to connect their factory equipment with their business networks. This is a key technology in smart manufacturing and Industry 4.0. Similar systems include Profinet and Modbus TCP.
