Omron PLCs

Omron Corp. has released the SYSMAC CJ2 programmable logic controller (PLC), Ethernet unit for CS/CJ series and CX-One FA Integrated Tool Package version 3.0 to support Ethernet/IP for industrial use. The company also announced the release of NS-series NS-V2 programmable terminals that have been upgraded to support Ethernet/IP.

These products help to reduce the total cost of ownership in designing and developing production equipment for immediate startup with quick delivery, as well as equipment that requires greater complexity and higher speed in control operations.

All the new products marketed by Omron support Ethernet/IP, a global standard industrial protocol promoted by the ODVA.2 In addition to the convenience of universal Ethernet, Ethernet/IP can be used for both information and control networks. Data links are faster (30x faster) and the data communications capacity is larger (9x the capacity). These features make the products suitable for production equipment that will require increasingly larger capacity and higher speeds in the future.

The SYSMAC CJ2 CPU units feature large capacity and a built-in Ethernet/IP-compatible multifunctional Ethernet port. The program capacity of 400K steps is 1.6x the capacity, while the 832K words of data memory is twice the capacity of previous Omron products. In addition, the CJ2 CPU units are designed for devices that require high speed and high precision with both faster speeds for executing special instructions, such as overseeing processing and floating-point math, and increased speed for immediate refreshing of basic I/O.

Also, less design time is required because PT screen data and PLC programming can be developed in parallel with improved tag access through Ethernet/IP for full access to memory in the CJ2 CPU unit from an NS-series programmable terminal.

CX-One FA Integrated Tool Package
The CX-One FA Integrated Tool Package that supports the SYSMAC CJ2 CPU units and the NS-V2-series PTs also supports Ethernet/IP. This provides an environment for setting up the all layers of FA networks, and allows users to set up both SYSMAC CJ2 CPU units and NS-V2-series PTs from the same software package.

The Ethernet/IP units for CS/CJ-series PLCs unify control and data networks by simultaneously using one port for FTP communications, data links and support software connections while providing high-speed data links and large-capacity data communications. Data links are 30x faster than previous Omron products and data communications capacity is 9x larger.

In addition, equipment costs are reduced because universal Ethernet is used, relieving the need to differentiate between information and control networks. Mobile communications systems can also be easily built with an FA WLAN.

Users can construct transparent systems from the sensors to the host with the same CIP protocol for Ethernet/IP, CompoNet, and DeviceNet.3 .The devices also offer greater freedom in wiring and easier maintenance with partial conversion to optical. Nodes can be added and withdrawn from the network while the network is active, and star wiring is possible using Ethernet switching.

NS-V2-series
For the NS-V2-series programmable terminals, the SYSMAC CJ2 CPU units are supported and memory in the CPU unit can be fully accessed. Development can be performed in parallel for the PLC, PT and host application using tags for data access through Ethernet/IP.

In addition, the Ladder Monitor display colors and size have been upgraded to greatly improve visibility. Ladder programming can be displayed even on the NS12 in the full screen size of 800 x 600 dots. Also, the NS-series PTs now support new search functions: Find Back, Find Next and Find Return. These search functions are popular with the CX-Programmer PLC Support Software, and they shorten the time required to debug PLC programming problems.

The series also offers improved operation log to provide information on what objects were touched and when. It is also possible to record operations on the touch panel and switch operations on the control panel, and to save the operation log in a Memory Card installed in the NS-series PT.

CX-One FA Integrated Tool Package Version 3.0
Lastly, the CX-One FA Integrated Tool Package Version 3.0 makes sure that data for all PLC units or specific PLC units at the target PLC can be backed up, compared and restored. This provides powerful support for data management for the entire PLC system. This version also supports Ethernet/IP and CompoNet in addition to the previous Ethernet, Controller Link and DeviceNet networks to allow users to easily build entire networks and set parameters.

Additionally, the tool package supports SYSMAC CJ2 CPU along with their USB ports and built-in Ethernet/IP port. It offers easier and safer support software connections to PLCs using PLC name verification to prevent incorrect connections. Tags can also be used to access data through Ethernet/IP using an NS-V2-series PT. Design modifications are easier because address changes at the PLC can normally be made without affecting the rest of the system.
