Overview

The SYSMAC CJ2 CPU Units are high-speed multi-functional CPU Units with a large memory capacity.
They provide the following features.
Fast, with Large Memory Capacity
Basic performance is faster and memory capacity has been increased to provide ample capability
for machine control.
Built-in EtherNet/IP Port
The CJ2 CPU Units support the EtherNet/IP open network as a standard feature. Support Software
connection and universal Ethernet communications, such as data links between PLCs, message
communications between PLCs, and FTP transfers, are all possible.
General-purpose Networks for Support Software Interface
Support Software and devices can be easily connected using commercially available cable to gen-
eral-purpose networks via USB and EtherNet/IP ports.
Tag Access
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.
Easier Programming
CJ2 CPU Units offer a highly readable programming environment, including features such as
addressing DM and EM Area bits, setting address offsets, and using array variables.
Improved Debugging
Online editing and data tracing have been improved, greatly increasing the efficiency of debugging.
