About this Manual:
This manual describes the operation of the CS/CJ-series EtherNet/IP Units and the built-in EtherNet/IP
ports on a CJ2 CPU Unit for constructing applications and includes the sections described below.
Please read this manual carefully and be sure you understand the information provided before
attempting to install or operate the EtherNet/IP Unit or built-in EtherNet/IP port. Be sure to read the
precautions provided in the following section.
Precautions provides general precautions for using the CS/CJ-series EtherNet/IP Units and built-in
EtherNet/IP ports.
Section 1 introduces the functions and protocols used in EtherNet/IP Unit or built-in EtherNet/IP port
communications services.
Section 2 provides the specifications of EtherNet/IP Units and introduces recommended network con-
figuration devices.
Section 3 explains how to install and make the initial settings required for operation of the EtherNet/IP
Unit or built-in EtherNet/IP port.
Section 4 describes the words allocated in the CIO Area and the DM Area for EtherNet/IP Units or
built-in EtherNet/IP ports.
Section 5 explains how to manage and use IP addresses.
Section 6 describes tag data link functions and related Network Configurator operations.
Section 7 describes message communications using FINS messages and explicit messages.
Section 8 provides information on communicating on EtherNet/IP Systems and interconnected net-
works using FINS commands. The information provided in the section deals only with FINS communi-
cations in reference to EtherNet/IP Units or built-in EtherNet/IP ports.
Section 9 describes message communications using FINS commands sent from the ladder program
in the CPU Unit of the PLC.
Section 10 describes the communications performance in an EtherNet/IP network, and shows how to
estimate the I/O response times and transmission delays.
Section 11 describes the functions provided by the FTP server.
Section 12 provides an overview of the automatic clock adjustment function, including details on spec-
ifications, required settings, operations from CX-Programmer, and troubleshooting.
Section 13 describes cleaning, inspection, and Unit replacement procedures, as well as the Simple
Backup Function.
Section 14 describes error processing, periodic maintenance operations, and troubleshooting proce-
dures needed to keep the EtherNet/IP network operating properly. We recommend reading through the
error processing procedures before operation so that operating errors can be identified and corrected
more quickly.
Appendices provide information on EtherNet/IP network parameters, the buffer configuration, TCP
status transitions, ASCII characters, maintenance, and inspections.

Unit Versions of CS/CJ-series
Unit Versions A “unit version” has been introduced to manage Units in the CS/CJ Series
according to differences in functionality accompanying Unit upgrades.
Notation of Unit Versions
on Products The unit version is given to the right of the lot number on the nameplate of the
products for which unit versions are being managed, as shown below.
■CS1W-EIP21/CJ1W-EIP21
■CJ2H-CPU@@-EIP/CJ2M-CPU3@
In this manual, the version of the EtherNet/IP port built into the CJ2H-
CPU@@-EIP/CJ2M-CPU3@CPU Unit is given as the unit version.
Confirming Unit Versions
with Support Software CX-Programmer version 4.0 can be used to confirm the unit version using the
Unit Manufacturing Information.
Note The unit versions of Pre-Ver.1.0 Units cannot be confirmed in Unit Manufac-
turing Information. The following dialog box is displayed.
In the IO Table Window, right-click and select Unit Manufacturing informa-
tion - CPU Unit.
The following Unit Manufacturing information Dialog Box will be displayed.
