CJ2 CPU Unit Hardware User’s Manual
This section describes the components related to the EtherNet/IP port section that is built into the
CJ2H-CPU6@-EIP and CJ2M-CPU3@.
Additional Information
The built-in EtherNet/IP port on the CJ2H-CPU6@-EIP provides the same performance and
functions as a CJ1W-EIP21 EtherNet/IP Unit. (The performance of the built-in EtherNet/IP port
on the CJ2M-CPU3@ is very different.) Set the unit number and node address with the rotary
switches on the front panel of the CPU Unit, and set the communications parameters with the
Edit Parameters menu command for the Special I/O Unit. For details on the Edit Parameters,
refer to 8-2 Setting CPU Bus Units and Special I/O Units in the CJ2 CPU Unit Software User’s
Manual (Cat. No. W473). For details on specifications and settings for the built-in EtherNet/IP
port, refer to the CS/CJ Series EtherNet/IP Units Operation Manual (Cat. No. W465).
With a CJ2 CPU Unit, Ethernet node status and Ethernet network status can be monitored by checking
the display and indicators at the upper right of the front of the CPU Unit.
