This manual is intended for the following personnel, who must also have knowledge of electrical sys-

tems (an electrical engineer or the equivalent).

•Personnel in charge of introducing FA systems.

•Personnel in charge of designing FA systems.

•Personnel in charge of installing and maintaining FA systems.

•Personnel in charge of managing FA systems and facilities.

For programming, this manual is intended for personnel who understand the programming language

specifications in international standard IEC 61131-3 or Japanese standard JIS B3503.

This manual covers the following products.

•CJ-series EtherNet/IP Unit

•CJ1W-EIP21

This manual contains information that is necessary to use a CJ1W-EIP21 EtherNet/IP Unit that is con-

nected to an NJ-series CPU Unit. Use a CJ1W-EIP21 EtherNet/IP Unit with unit version 2.1 or later for

an NJ-series CPU Unit. Also use a CPU Unit with unit version 1.01 or later and Sysmac Studio version

1.02 or higher.

Relevant Manuals

There are three manuals that provide basic information on the NJ-series CPU Units: the NJ-series CPU

Unit Hardware User’s Manual, the NJ-series CPU Unit Software User’s Manual, and the NJ-series

Instructions Reference Manual.

Most operations are performed from the Sysmac Studio Automation Software. Refer to the Sysmac Stu-

dio Version 1 Operation Manual (Cat. No. W504) for information on the Sysmac Studio.

Other manuals are necessary for specific system configurations and applications.

Read all of the manuals that are relevant to your system configuration and application to make the most

of the NJ-series CPU Unit.

4-3 Mounting Units

The Units that make up an NJ-series Controller can be connected simply by pressing the Units together

and locking the sliders by moving them toward the back of the Units. The End Cover is connected in the

same way to the Unit on the far right side of the Controller.

1Join the Units so that the connectors fit exactly.

2The yellow sliders at the top and bottom of each Unit lock the Units together. Move the sliders

toward the back of the Units as shown below until they click into place.
