3 EtherNet/IP™ information
3.1 General
EtherNet/IP™ was developed by Rockwell Automation and the ODVA™ as an open
field bus standard, based on the Ethernet Industrial Protocol and is standardized in the
international standards IEC 61158:2003 Type 2 and IEC 61784-1:2003 CP 2/2 Type 2.
Specification and maintenance of the EtherNet/IP™ standard is regulated by the
ODVA™.
EtherNet/IP™, along with ControlNet and DeviceNet™, belongs to the family of CIP™-
based networks. The CIP™ (Common Industrial Protocol) forms a common
application layer for these 3 industrial networks. DeviceNet™, ControlNet and
Ethernet/IP™ are therefore well matched to one another and present the user with a
graduated communication system for the physical layer (Ethernet/IP™), cell layer
(ControlNet) and field layer (DeviceNet™). EtherNet/IP™ is an object-oriented bus
system and works according to the producer/consumer model.
