Built-in EtherNet/IP Port (CJ2H-CPU6@-EIP and CJ2M-CPU3@ Only)
The CJ2 CPU Units provide as standard equipment a built-in EtherNet/IP port that supports the same
FINS Ethernet functions as an Ethernet Unit (including features such as an FTP server and time coordi-
nation) as well as the EtherNet/IP open network.
High-speed, High-capacity Data Links with User-set Refresh Cycles
The CJ2 CPU Units provide high-speed, high-capacity data links, and refresh cycles can be set indi-
vidually for each data link area.
In addition, using the EtherNet/IP DataLink Tool makes it possible to set the data links using an inter-
face similar to that of the Controller Link automatic data link setup.
General-purpose Networks for Support Software Interface
Built-in USB and EtherNet/IP Ports
A commercially available USB cable can be used to connect to the PLC directly from a USB port on
a personal computer. In addition, with the CJ2H-CPU6@-EIP or CJ2M-CPU3@, a PLC on the Ether-
Net/IP network can be accessed via USB.
Prevent Connecting to the Wrong PLC by Using PLC Names from Support
Software
A user-set PLC name can be recorded in a CJ2 CPU Unit. When using Support Software to connect
online to a PLC, verification of the PLC name prevents incorrect connections from the Support Soft-
ware.
