EtherNet/IP Introduction
EtherNet/IP Introduction
Ethernet/Industrial Protocol (EtherNet/IP) is a fieldbus communications protocol that was ini-
tially developed in the 1990s. It is now a CIP-based technology that is managed by the Open
DeviceNet Vendors Association (ODVA), which is a standards organization that manages all
CIP network technologies.
EtherNet/IP and DeviceNet are two CIP network technologies that are supported by Moog
Animatics (see OSI Model for EtherNet/IP and DeviceNet on page 18). These networks share
the same CIP layers and use objects to describe the network devices (this collection of objects
specific to a device is the device profile). Because of this, they are able to communicate with
each other. For example, a device on an EtherNet/IP network can communicate with one on a
DeviceNet network. For more information on CIP objects, see Objects on page 21.
The Class 6 EtherNet/IP SmartMotor is designed to operate as a device on an EtherNet/IP net-
work. This allows the system designer to take advantage of SmartMotor technology through
its device profile (for example, start a user program stored in the SmartMotor). For details on
the SmartMotor device profile using the Position Controller device, see SmartMotor Device
Profile Overview on page 33.
The full specification for EtherNet/IP is available from the ODVA.org website. For details, see
THE CIP NETWORKS LIBRARY Volume 1 - Common Industrial Protocol (CIP™)
and
THE CIP
NETWORKS LIBRARY Volume 2 - EtherNet/IP Adaptation of CIP
.
The OSI Model
The OSI model describes the architecture for the CIP-based industrial network protocols.
Moog Animatics supports EtherNet/IP and DeviceNet using the Position Controller Supervisor
and Position Controller profiles. The other profiles shown are not currently supported.
