The 1783-ETAP is a specialized communication module designed to add Device Level Ring (DLR) connectivity to single-port EtherNet/IP devices. While many modern Allen-Bradley controllers and drives have dual Ethernet ports built-in, older or simpler devices (like the PowerFlex 40 or older CompactLogix) only have one port. The ETAP acts as a bridge to pull those devices into a high-availability ring network.
