Rockwell Automation has embedded Ethernet Device Level Ring (DLR) technology into its Integrated Architecture system for high-speed, high-performance applications needing resilient networks, and for machine builders looking for flexible, reliable, low-cost network solutions for their real-time EtherNet/IP applications. DLR is a network technology for industrial applications that takes advantage of embedded switch functionality in automation end devices, such as I/O modules and programmable automation controllers, to enable Ethernet ring network topologies at the device level. Unlike a network- or switch-level ring topology that provides resilience to the network infrastructfure, DLR technology adds device-level network resilience to optimise machine operation. When a DLR detects a break in the ring, it provides alternate routing of the data to help recover the network at extremely fast rates. Enhanced diagnostics built into DLR-enabled products identify the point of failure, helping to speed maintenance and reduce mean time to repair. In addition to superior network recovery performance, DLR technology helps simplify network architecture while still providing the flexibility to connect and coexist with other network topologies. Multiport EtherNet/IP devices equipped with DLR technology connect directly to neighbouring nodes and form a ring topology at the end devices. DLR technology reduces the number of external components and associated cabling, which eases design and installation for machine builders. ODVA, an international association comprised of members from the world's leading automation companies, recently extended the EtherNet/IP specification to include the DLR protocol, creating a network solution for multivendor EtherNet/IP systems. By complying with a single standard ring specification, manufacturers using DLR-enabled products can achieve interoperability and numerous benefits provided by the EtherNet/IP network.
