Overview
The Allen-Bradley 1783-ETAP1F is a 3-port EtherNet/IP TAP featuring embedded switch technology that combines 2 copper Ethernet ports and 1 fiber-optic port. The embedded switch technology allows you to connect devices directly to your network without a separate Ethernet switch, reducing overall cost and simplifying system configuration. This combination enables engineers to build hybrid copper-fiber networks within industrial automation systems.
Key Features
- Two copper Ethernet ports and one fiber optic port, both supporting 10/100 Mbps
- LC fiber optic connector for high-speed, full-duplex communication
- Allows high-performance ring capability with make/break less than 3 ms and fast recovery to lower downtime
- Supports linear or ring topology without additional hardware
- Built-in diagnostic LEDs for OK and Link status indicators
- IP address configuration via DIP switches, RSLogix 5000, Studio 5000 Logix Designer, RSLinx Classic, DHCP, or BOOTP

Typical Applications
The 1783-ETAP1F is used for linking Allen-Bradley devices such as controllers, communication and visualization devices for implementation of industrially approved automation systems. It enables users to combine copper and fiber networks, with fiber networks ideal for covering longer distances between points and less susceptible to electrical noise, providing clearer signals. Common uses include:
- Plant-wide EtherNet/IP network backbone expansion
- Extended-distance industrial control networks using fiber segments
- Ring topology automation systems requiring fast fault recovery
- Mixed-media facility integration across large industrial sites
