Section 1 introduces the features, describes the system configuration and Unit parts, and provides
Unit specifications.
Section 2 explains how to install the Ethernet Unit and make the initial settings required for operation.
Section 3 provides information for setting communications using CX-Programmer.
Section 4 describes the words allocated in the CIO Area and the DM Area for Ethernet Units.
Section 5 explains how to manage and use IP addresses.
Section 6 provides information on communicating on Ethernet Systems and interconnected networks
using FINS commands.
Section 7 describes the FINS commands that can be sent to an Ethernet Unit and the responses that
are returned by the Ethernet Unit.
Section 8 describes information and procedures that can be used to troubleshoot problems that some-
times occur with Ethernet Unit and Ethernet communications.
