The Allen-Bradley 1783-ETAP is a 3-port EtherNet/IP tap that enables non-DLR devices to connect to redundant ring topologies. It features high-speed 10/100 Mbps ports, 24V DC power, and rapid fault recovery for industrial networks.
The Allen-Bradley 1783-ETAP serves as a high-performance three-port EtherNet/IP tap designed to facilitate the integration of standard Ethernet devices into a Device Level Ring (DLR) topology. This module functions by providing a dedicated connection point for single-port devices—such as older PLCs, HMIs, or frequency drives—allowing them to participate in a redundant network without requiring a hardware overhaul. By implementing this tap, engineers ensure that their automation assets remain connected even if a network cable is severed.
Network reliability drives the core architecture of the 1783-ETAP. The module utilizes two ports to form the primary ring backbone, while the third port provides the local connection to the end device. Because the unit supports the DLR protocol, it monitors the network state constantly and can detect a link failure within milliseconds. Consequently, the system reroutes data packets instantaneously to maintain process continuity. This high-speed recovery is essential for motion control and synchronized I/O applications where even minor latency can cause system-wide shutdowns.
Installation and diagnostics are streamlined through a rugged, industrial-grade design. The hardware operates on 24V DC power and features a compact footprint suitable for dense DIN-rail mounting. Furthermore, the front panel incorporates a series of LED status indicators that provide real-time feedback on link activity and ring status. Because the module integrates seamlessly with the Studio 5000 environment, users can perform remote configuration and diagnostics via standard Add-On Profiles (AOP). This integration reduces commissioning time and simplifies long-term network management in complex manufacturing environments.
