ROCKWELL Automation has installed an Ethernet-based device-level ring (DLR) technology into its control and motion products.
Rockwell Automation says the Ethernet-based DLR technology will be incorporated into its Allen-Bradley ControlLogix controllers, I/O systems and Kinetix motion systems.
Rockwell Automation’s Ethernet-based DLR technology uses switch functions embedded into automation end-devices such as I/O modules and Programmable Automation Controllers (PACs) to enable Ethernet ring network topologies at the device level.
Rockwell Automation claims that the Ethernet-based DLR technology adds device-level network resilience to optimise machine operation.
The Ethernet-based DLR technology is also able to detect a break a ring and provide alternate routing for the data to help recover the network rapidly.
According to Rockwell Automation, the Ethernet-based DLR provides flexibility to connect with co-existing network topologies reducing the need for external components and cabling.
