Overview
The Allen-Bradley 1783-ETAP is an embedded Ethernet switch tap designed for EtherNet/IP automation networks. This 3-port tap provides a compact solution for expanding network connectivity in industrial automation systems. The 1783-ETAP uses embedded switch technology to support single-port devices that need to connect to the network without requiring a separate Ethernet switch, reducing overall system cost and complexity.
Key Features
- 3 Copper Ports: All three ports support 10/100 Mbps full or half duplex operation
- Embedded Switch Technology: Embeds Ethernet switch features into hardware to support high performance applications and allows devices to connect directly to the network without a separate Ethernet switch
- Network Topology Support: Supports linear and device-level ring (DLR) topologies for EtherNet/IP applications
- Auto-Negotiation: Ports auto-negotiate link speeds (10 Mbps or 100 Mbps) and duplex settings (full or half)
- Ring Supervisor Capability: Supports Ring Supervisor mode on firmware revision 2.001 or later
- Studio 5000 Compatible: Download the tap Add-on Profile (AOP) if using Studio 5000 Logix Designer application, version 17.01
