Section 1 Introduction
Overview
The Industrial Ethernet Protocol (EtherNet/IP) is the combination of traditional
Ethernet and an industrial application layer protocol, called the Common Industrial
Protocol (CIP). EtherNet/IP is used in industrial automation applications.
DeviceNet is a low-level industrial application layer protocol, based on Common
Industrial Protocol, for industrial automation applications. DeviceNet is built on the
standard Controller Area Network (CAN).
Both EtherNet/IP and DeviceNet have several features in common with CIP. Both
serve as communication networks between industrial controllers and I/O devices.
CI873 Communication Interface Module
EtherNet/IP device interfaces with the AC 800M controller, through the CI873
communication interface module. CI873 acts as an EtherNet/IP I/O scanner class
device. It originates connections to EtherNet/IP enabled devices and exchanges real
time I/O data with them.
The CI873 communication interface provides the following functionalities:
• Configuration of EtherNet/IP and DeviceNet devices.
• CI873 as EtherNet/IP I/O scanner.
• I/O communication with EtherNet/IP and DeviceNet devices using Class 1
connection.
• Status supervision of CI873, EtherNet/IP, DeviceNet, and Linking devices.
CI873 originate a Class 1 connection to Linking device (LD 800DN) for
DeviceNet device status.
• Hot swap of CI873, LD 800DN, DeviceNet, and EtherNet/IP devices.
