Overview

Since 2001,
CJ1M-series PLCs are in control of a wide variety of applications worldwide.

The accumulated experience and advanced technology now result in CJ2M:

Fully Compatible with CJ1 Units, Yet With Better Performance!

The CJ2M Series Programmable Logic Controller is ideal for packaging and general machine automation needs. Connectivity is assured thanks to the built-in USB port and the choice of Ethernet and RS-232C/422/485 interfaces on the CPU.

* Supported by the CJ2M CPU Unit with version 2.0 or later.

Pulse I/O Modules

By mounting optional pulse I/O modules, you can extend the functionality of any CJ2M CPU with:

• Interrupt inputs
• High-speed counters
• Incremental encoder inputs
• Pulse frequency control outputs
• Pulse width control outputs

Up to two modules can be mounted per CPU, allowing direct control of four motion axes. Using dedicated instructions, these axes can be controlled directly by the PLC program, without communication delays.

Benefits / Features

Built-in Ethernet/IP Port

Reduce Network Installation and Wiring Cost

CJ2 CPU Units are available with Ethernet/IP ports, which can be used with peripheral devices for universal Ethernet technology, e.g. cables, hubs and wireless devices.

Multiple Functions Can Be Executed Simultaneously on One Port.
Support Software, Data Links, Message communications between PLCs, FTP Communications

Easy to build the system without changing the port connection.

Efficient Programming with Tag Symbols

Previously, when data was exchanged by specifying address and addresses were changed, the program had to be changed at other Controllers and various operations, such as memory checks, had to be performed.

Now, tag names reduce the dependence on a memory map and the need for checking items affected by changes. This allows equipment to be easily added or upgraded.

* CJ2M-CPU3☐ : 2,000 max.

Versatile Position Control

Advanced Motion Control System with Low Cost and Easy Operation
No Special Controller Is Required. Build Your System with Ladder Diagrams.

The lineup now includes Position Control Units with EtherCAT communications in additions to models with pulse-train outputs. The CJ2 Programmable Logic Controller covers a wide range of applications from positioning control to synchronized multi-axis control.

The Position Control Units with EtherCAT interface use the same positioning functions* as high-speed pulse-train Position Control Units, and the programming interface is also the same.

You can easily switch the unit type between the Position Control Units depending on the application.

* Except Synchronised multi-axis

Easy Startup of Network, High-speed Starting of Pulse-train Control   Up to 16 axes 

Industry's HIGHEST Class Performance

Faster, More Precise Systems, with Less Wiring

High-speed starting and control performance equivalent to those of pulse-train systems are now possible via EtherCAT network connections.

* A CJ2M CPU Unit is required.

Applications

 
Tension Control

Benefit: Reduce takt times, eliminate inconsistencies in I/O processing times

Direct conversion enables faster input of analog values into the CJ2 CPU Unit.

Inline Measurement

Benefit: Improve the accuracy of NG product detection

Analog quantities are input in ultra-high speed (20μs).

High-speed Serial Input from Laser Distance Meters

Benefit: Achieve high-speed data input from measurement sensors

Transfer position data to the CPU Unit from laser distance meters with short measurement cycles without missing data to achieve precise control of inverters for conveyors and elevators.

High-speed Serial Input from Barcode Readers

Benefit: High-speed sorting control

Data from the barcode reader is transferred quickly to the CPU Unit to recognize the code and output pulses at high speed.

Multi-axis Position Control via EtherCAT

Benefit: Reduce production takt time

Palletizing: A starting time of 0.4 ms helps reduce the takt time of applications that perform repeated positioning.
