DLR is network technology provided by Rockwell Automation to enable Ethernet ring network topologies at the device level. The DLR protocol enables Ethernet devices to connect directly to neighboring nodes through dual network ports to form a ring topology.
When a DLR detects a break in the ring, it provides alternate routing of the data to help recover the network.
The ABCIP Communication Driver provides data connectivity to other supported controllers connected on the same DLR network. The computer where the ABCIP Communication Driver is installed must be connected to the DLR network via the 1783-ETAP device. Following is a sample DLR topology:
