Product description
EtherNet/IP communication
EtherNet/IP is based on the standard Ethernet FRAME. This contains the Ethernet header,
the Ethernet data and the Ethernet trailer. The MAC addresses of the receiver (destination
address) and of the source (source address) are contained in the Ethernet header.
The Ethernet data field consists of several nested protocols:
The IP datagram is transported in the user data of the Ethernet data field.
The TCP segment or the UDP datagram are transported in the user data of the IP
datagram.
The CIP protocol is transported in the user data of the TCP segment or of the UDP
datagram.
