3-1-2 Built-in EtherNet/IP Section
This section describes the components related to the EtherNet/IP port section that is built into the
CJ2H-CPU@@-EIP.
Additional Information
The built-in EtherNet/IP port provides the same performance and functions as a CJ1W-EIP21
EtherNet/IP Unit. 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.
z Status Indicators: MS, NS, COMM, 100M, and 10M
The MS (Module Status) indicator indicates the status of the built-in EtherNet/IP port itself and the
NS (Network Status) indicator indicates the status of the network.
The COMM, 100M, and 10M indicators indicate the status of Ethernet communications.
