EtherNet/IP

2 EtherNet/IP
EtherNet/IP, which is accepted worldwide, is an industrial communication
protocol standardized by ODVA (Open DeviceNet Vendor Association) on
the basis of Ethernet. It is based on the widely used transport protocols TCP/
IP and UDP/IP (standard). EtherNet/IP thus provides a wide basis, supported
by leading manufacturers, for effective data communication in the industry
sector.
EtherNet/IP adds the industry protocol CIP (Common Industrial Protocol) to
the Ethernet as an application level for automation applications. Ethernet is
thus ideally suited to the industrial control technology sector.
