Understand EtherNet/IP — the Common Industrial Protocol (CIP) running on standard Ethernet — how it compares to Modbus, how implicit and explicit messaging work, and when to use it in industrial automation.
EtherNet/IP (Ethernet Industrial Protocol) is an industrial communication standard developed by Rockwell Automation and now managed by ODVA (Open DeviceNet Vendors Association). It runs the Common Industrial Protocol (CIP) over standard TCP/IP and UDP/IP networks — meaning it uses the same physical Ethernet infrastructure as office IT networks, while providing real-time industrial control capabilities.
