Key Features and Benefits
Large Memory Capacity –
The CPU program memory capacity has been 
increased up to 400K Steps, DM has increased 
up to 800K while Function Block Program, 
Symbol, Comment Memory has increased to 
3.5MB. Large memory allows for larger more 
versatile programs, well documented programs 
makes it easier and faster to troubleshoot.
Fast –
Processing times are significantly faster. Faster 
production, faster development time, faster time 
to market and higher throughput means higher 
speed applications can be achieved.
IEC61131-3 Programming –
All 5 programming languages are supported 
with the CJ2 PAC. Ladder, Function Block, 
Structured Text, Instruction List and Sequential 
Function Chart. Hundreds of Pre-built pre-test 
Function blocks significantly can reduce design 
time. Standard programming languages allow 
for fast, flexible and powerful programming.
General-purpose Networks 
for Support Software 
Interface –
CX-One software applications can be easily 
connected using standard USB and EtherNet 
Cables via USB and EtherNet/IP ports. 
Tag Based Programming –
CJ2 CPU Units have a tag name server to 
manage tag names and I/O addresses.
This enables access from external devices
using tag names, without needing to know the 
I/O addresses.
One Single Programming 
Environment –
CX-One is Omron’s single programming 
environment for PAC’s, PLC’s, HMI, Networks, 
Process Control, Motion Control and Simulation 
Software. Legacy PLC’s are supported and single 
click conversion to new hardware makes for easy 
migration. The software includes and Update service 
that automatically checks for the latest update of 
software.
Improved Debugging –
Online editing and data tracing have been 
improved, greatly increasing the efficiency of 
debugging. The data trace function is built into the 
PAC and can monitor & store I/O and data in 1 
ms time increments. This allows for easy and faster 
debug time, which allows for faster time to market. 
CJ2 Capabilities –
 Offers functions such as motion control, process 
control, RFID, Logic and Drives all on the same 
controller platform. The modular architecture is 
ideal for applications where the user is interested 
in saving money by reducing development time & 
increasing production.
