CJ-series EtherNet/IP Unit
last update: June 12, 2023
The ODVA promotes the spread of Industrial Ethernet all over the world.
EtherNet/IP can be used to communicate with many devices from various companies around the world in addition to OMRON components (such as Temperature Controllers and Sensors). The use of EtherNet/IP will rapidly increase the development of an EtherNet/IP multivendor environment (including robots and safety devices).
Seamless communications on the control line and information monitoring line with EtherNet/IP
Using the global standard open protocol (CIP), an independent network system can be created with seamless data flow between the control line and the information monitoring line.
OMRON FINS message communications can also be used on the same network because it is a standard LAN.
Use the same operating procedures for both EtherNet/IP and DeviceNet Support Software.
The same Support Software procedures can be used from a remote location for device configuration, monitoring, and program transfer for the DeviceNet and EtherNet/IP networks.
Safety systems can be monitored through the EtherNet/IP.
The safety system can be monitored from a PLC by using a modular designed Safety Control Unit with a EtherNet/IP Coupler Unit.
High-capacity communications with high-speed high-capacity bus
All types of data, from process interlocks and manufacturing recipes to production data, can be exchanged at high speed and with optimal timing. The ability to communicate is incomparably better than previous networks, such as the Controller Link and FL-net.
Note: Using a built-in EtherNet/IP port on CJ2H and EtherNet/IP Units.
Flexible topology with the Ethernet switch
Flexible wiring and expansion are possible with Ethernet switches. This means that there will be no total network crashes caused by communications path errors, ensuring high network performance and security.
- Joining and leaving the network is possible during communications.
Nodes can leave the network during operation, enabling easy maintenance for error detection, separation, and restoration.
- Unpredictable delays caused by data collisions are minimum.
- Problems caused by wiring errors are minimized to each line.
Star topology using Ethernet switch technology
Generic LAN cables can be used.
- Metal cables of category 5, 5e, or higher can be used as LAN cables.
- Generic RJ-45 connectors can be used.
There is no need to rewire even when layout has been changed.
Flexible and high-speed cyclic communications
With the multipurpose EtherNet/IP port, an Ethernet Unit is not required for expansion.
Using the multipurpose EtherNet/IP port built into a CJ/NJ/NX/NY CPU Unit, a single port can be used for data link communications between PLCs, messages between PLCs, and Universal Ethernet communications, such as FTP transfers while connecting Support Software. An EtherNet/IP Unit can be added to any CS/CJ-series PLC to achieve the same functions.
