Innovation without growing pains
As a modern machine manufacturer you need to
continuously increase the intelligence and flexibility
of your product to remain competitive. But you also
need to be absolutely certain that it all works
perfectly, first time, every time.
The CJ2 is the result of years of experience as market
leader in the field of modular controllers and
represents a logical next step in controller design. It
offers greater performance and faster I/O response
as well as extreme scalability - so you will only need
one family. In addition, programming, debugging
and networking are faster and easier. Welcome to the
new CJ2 Family: built to give you innovation without
growing pains.
Although CJ2 can directly replace any CJ1 CPU, it oers
the following additional significant advantages:
Open to the world
Data communication is via standard Ethernet port with
EtherNet/IP Data Link function.
Always accessible
The standard USB and Ethernet ports give you instant
access for programming, commissioning, maintenance
and troubleshooting.
Learn one, know them all
Thanks to the wide variety of CPUs with consistent
architecture across all PLC families, you only need to
learn one, and you will know them all.
Highly flexible
Adapt the PLC to your needs with the wide variety of
compatible CJ1 Family I/O units (nearly 100).
