Proven track record
The CJ2 Family is based on the highly popular CJ1,
which after its launch in 2001 now operates in
an extraordinary variety of applications all over
the world. Now, as the natural successor, the CJ2
combines that field-proven technology with a
wider choice of CPUs, more speed and memory,
and a wider variety of communication interfaces.
Faster development
Tag-based communications technology will
simplify the interfacing of the PLC to the outside
world. On-line debugging improvements also help
to accelerate software development so you can
change the code and test the results quickly. The
added function block memory will allow you to
improve program structure and reuse code even
in the the entry-level models.
Talks to all
The CJ2 Family supports major open networking
technologies including:
Ethernet-based communication based on open •
industrial standards
Serial communications over RS-232 C, RS-422, •
RS-485 and USB
The major open Fieldbus standards •
Fast and accurate motion control networks.•
The wide range of CPUs means you need only
to get familiar with one PLC family for use in
everything from simple stand-alone applications
up to networked, high-speed machines.
