The DeviceNet functionality built into the NSJ Controller is equivalent to the
functionality of the CJ-series DeviceNet Unit (CJ1W-DRM21). Refer to the fol-
lowing manuals for communications specifications, wiring methods, and func-
tional details.
• DeviceNet Operation Manual (W267)
• CS/CJ Series DeviceNet Unit Operation Manual (W380)
One of the NSJ Expansion Units can be mounted to enable connecting CJ-
series Expansion Racks, to add a Controller Link port, or to add an Ethernet
port. Refer to SECTION 5 Installation and Wiring for mounting methods.
An NSJ I/O Control Unit (NSJW-IC101) can be mounted to enable connecting
one CJ-series Expansion Rack to the NSJ@-@@@@-M3D or up to three CJ-
series Expansion Racks to any other NSJ Controller. Up to 10 CJ-series I/O
Units (Basic I/O Units, Special I/O Units, or CPU Bus Units) can be mounted
to each Expansion Rack. The maximum number of I/O Units that can be con-
nected in one NSJ Controller is thus 10 for the NSJ@-@@@@-M3D and 30 for
any other NSJ Controller. Each Expansion Rack must have a Power Supply
Unit and I/O Interface Unit (CJ1W-II101).
The maximum cable length for connecting all of the Expansion Racks is 12 m.
10 Units max.
