Omron NJ Ethernet

Product Overview

The Omron NJ Ethernet driver manages communications between OPC clients and Omron Sysmac NJ EtherNet/IP PLCs via the EtherNet/IP protocol. It also supports Common Industrial Protocol (CIP) routing to access additional PLCs via EtherNet/IP without requiring the use of CX-Compolet. Kepware automatically optimizes data acquisition based on client demand and ensures data integrity through extensive error handling.

• Supports EtherNet/IP over TCP/IP
• Supports Common Industrial Protocol (CIP) routing from one Omron NJ device to another. Features a CIP-configurable packet size from 500 bytes to 1996 bytes per packet.
• Supports symbolic addressing of basic data types and structures. Supported data types include the following: BOOL, SINT, USINT, INT, UINT, DINT, UDINT, LINT, ULINT, REAL, LREAL, and String.
• Supports read blocking and multi-servicing of writes to arrays to optimize performance when reading and writing to multiple items within an array
• Supports Client Arrays for referencing contiguous array elements by the client
• Supports Automatic Tag Generation, featuring direct interrogation of the controller and the ability to map structured data on the controllers into multi-level tag groups
• Supports the reading of system variables defined on the controller
• Communicates directly with Omron Sysmac NJ devices over EtherNet/IP without any dependency on third-party products (such as Sysmac Gateway and CX-Compolet)
