EtherNet/IP: Industrial Protocol White Paper

DeviceNetTM and ControlNetTM are two well-known industrial networks based on the CIP protocol (CIP = Control an Information Protocol). Both networks have been developed by Rockwell Automation, but are now owned and maintained by the two manufacturer's organizations ODVA (Open DeviceNet Vendors Association) and ControlNet International. ODVA and ControlNet International have recently introduced the newest member of this family – EtherNet/IP ("IP" stands for "Industrial Protocol"). This paper describes the techniques and mechanisms that are used to implement a fully consistent set of services and data objects on a TCP/UDP/IP based Ethernet® network.
