Networks Are More Open
EtherNet/IP is an open network that uses the TCP/IP protocol on EtherNet networks, which are widely used
in offi ces and factories throughout the world. The CJ2 CPU Units support EtherNet/IP as a standard feature.
Because EtherNet/IP uses TCP/IP, it provides the many advantages of EtherNet technology.
Universal EtherNet and FA Data Links Can Be Used at the Same Time.
With EtherNet/IP, One Port Is Enough.
FTP Communications, Data Links, and Support Software Can Be Used Simultaneously through
a Single Port.
The CJ2 CPU Units provide as standard equipment a multifunctional EtherNet port that supports EtherNet/
IP. There is no need to add an EtherNet Unit, because universal EtherNet communications, such as data links
between PAC’s, message communications between PAC’s, and FTP transfers, are all enabled simultaneously
through this one port while Support Software is connected.
Create a Seamless Data Flow in a Single Network System.
Because it is based on the world-standard CIP open protocol, a seamless data fl ow can be achieved between
control lines and information monitoring lines in a single network system. From here on, EtherNet/IP will be
increasingly used in multi-vendor environments (such as robotics and safety devices).
