CJ2 – Omron’s New Small, Fast & Flexible
Modular Flagship PAC, with built-in
EtherNet/IP and Tag Based Programming
The CJ2 Programmable Automation Controller (PAC) delivers PAC features and capabilities as
defined by ARC Advisory Group in Omron’s popular, compact modular CJ PLC platform.
Multi-domain functionality – CJ2 performs logic, motion, HMI and process control on a single platform.
Single multi-discipline development platform - Using a common tag database, PAC and HMI
programming can be developed in parallel, reducing development time. Omron’s CJ2 PAC, NS-Series
HMI’s and middleware all share the same tag database. CX-One Software incorporates 16 different
development tools.
Software tools that allow access across several machines - Omron’s CJ2 PACs supports Single
Point Multiple Access (SPMA) which enables set-up and programming of all local modules and remotely
networked modules.
Open, modular architecture - Omron’s CJ2 supports the capability to handle logic, position & motion
control, RFID, analog and temperature control, HMI, bar code, networking modules, communication
modules, smart sensors, vision and drives, all in a single modular platform.
Standardized Programming & Open Networks - Omron’s CJ2 supports all IEC61131-3 programming
languages: Ladder, Function Block, Structured Text, Sequential Function Chart (SFC) and Instruction List.
Open networks enable seamless communications using these protocols: Ethernet, EtherNet/IP, DeviceNet,
CompoNet, PROFIBUS, PROFINET, FLNet, MECHATROLINK-II and Serial (RS-232C, RS-422, RS-485).
CJ2 CPU’s – Offer built-in EtherNet/IP networking, High-speed, high-capacity data exchange between
PAC’s, PLC’s, HMI’s and I/O devices. EtherNet/IP can be used to perform both information and control
Networking, share up to 184,832 words over 256 nodes. CJ2 PAC’s can easily connect to Rockwell’s
ControlLogix and CompactLogix PLC’s using EtherNet/IP tag data links.
