2. ETHERNET/IP - GENERAL INFO
EtherNet/IP™ is industrial Ethernet network solution available for manufacturing automation.
CIP™ (Common Industrial Protocol) encompasses a comprehensive suite of messages and services
for a variety of manufacturing automation applications, including control, safety, synchronization,
motion, configuration and information. CIP provides users with unified communication architecture
throughout the manufacturing enterprise.
2.1 Connections and Wiring
The Vacon 100 drive supports 10/100Mb speeds in both Full and Half-duplex modes. The drive
must be connected to the Ethernet network with a shielded CAT-5e cable. Use a so called crossover
cable (at least CAT-5e cable with STP, Shielded Twisted Pair) if you want to connect the drive direct-
ly to the master appliance.
Use only industrial standard components in the network and avoid complex structures to minimize
the length of response time and the amount of incorrect dispatches.

2.1.1 Technical details
EtherNet/IP is a connection-oriented communication protocol designed for use in industrial envi-
ronments. The protocol allows simple and complex industrial devices to communicate with each
other.
Standard Ethernet and TCP/IP technology is used by the EtherNet/IP protocol. There are different
messaging forms in EtherNet/IP:
• Connections are established using so-called "Unconnected Messaging”,
• Real-time I/O data transfer happens through "Connected Messaging”
There are two kinds of connections in EtherNet/IP:
• General-purpose, point-to-point connections are known as "Explicit Messaging Connec-
tions". These messages are sent using the TCP protocol.
• Connections for moving application-specific I/O data at regular intervals are known as
"Implicit Connections" or "I/O Data Connections". These messages are sent using the UDP
protocol
