Description

Introducing the Flagship CJ2 CPU Units, with Built-in Multifunctional Ethernet Port.

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 Omron PLC CJ2 SERIES 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.

*12. The EtherNet/IP port is built into the CJ2H-CPU6@-EIP and CJ2M-CPU3@ only.

*13. “Packets per second” is the number of communications packets that can be processed per second.

*14. When using the EtherNet/IP Unit with version 3.0 or later. When using the EtherNet/IP Unit with version 2.1 or earlier, the maximum allowed communications bandwidth per Unit is 6,000 pps. When using the EtherNet/IP Unit with version 3.0 or later, the Network Configurator with version 3.57 or higher is required.

*15. Large Forward Open (CIP optional specification) must be supported in order for 505 to 1,444 bytes to be used as the data size. Application is supported between

CS/CJ-series PLCs. When connecting to devices from other manufacturers, make sure that the devices support the Large Forward Open specification.

*16. Unit version 2.0 of built-in EtherNet/IP section: 20 words.

*17. If the maximum number is exceeded, refreshing will require more than one CPU Unit cycle.

*18. When changing parameters, however, the EtherNet/IP port where the change is made will be restarted. In addition, a timeout will temporarily occur at the other node that was communicating with that port, and it will then recover automatically.

*19. The EtherNet/IP port supports an IGMP client, so unnecessary multicast packets are filtered by using an ethernet switch that supports IGMP snooping.
