CHAPTER 9: ETHERNET/IP PROTOCOL
9.1 Ethernet/IP Overview
Ethernet/IP protocol is ODVA’s Common Industrial Protocol (CIP) over Ethernet. Figure 9.1
illustrates the protocol layers. Ethernet/IP starts at the Ethernet Physical Layer, and moves up
through the IP, TCP/UDP, and Encapsulation Layers. It is beyond the scope of this supplement to
discuss the specifics of the Ethernet/IP protocol. See the Ethernet/IP specification at
http://www.odva.org for more details of the Ethernet/IP protocol.
Figure 9.1 - Ethernet/IP Protocol Layers
The Ethernet Module provides Ethernet/IP server capability, and implements the following CIP
objects:
• Identity Æ Instance #1
• Connection
Manager Æ Instance #1
• Message
Router Æ Instance #1
• Assembly Æ Instance #100 (0x64) for Consumed data
• Assembly Æ Instance #101 (0x65) for Produced data
• TCP/IP Æ Instance #1
• Ethernet
Link Æ Instance #1
The Ethernet Module has an Unconnected Message Manager (UCMM), which forwards the
following services on to the addressed object:
• Forward Open (Connection Manager object service)
• Forward Close (Connection Manager object service)
• Get Attribute Single
• Set Attribute Single
It will forward the above services on to the addressed object, however the addressed object may
or may not support the service.
