RAPIEnet

• An Ethernet-based industrial networking protocol developed in-house by LSIS guarantees real-time transmission and is registered as an international standard.
• An embedded Ethernet switch with two ports enables the network expansion in a daisy chain without the need for an additional external switch, easy installation and wiring reduction.
• With 100Mbit/s/1Gbit/s transmission speed, electrical and optical media can be used together.
• Supports transmission modes such as Unicast, Multicast and Broadcast.
• Supports "Store & Forward”and “Cut Through” switching.

  RAPIEnet Technology

Protocol Stack Structure

Embedded dual port switch motion

• An embedded hardware-based switch is adopted for real-time data transmission.
• With the full-duplex communication support, each node has dual link routes in a ring topology.

  Frame Format

• RAPIEnet Ether type: 0x88FE

  Topology

Recovery System

• With an embedded switch and full-duplex, it has dual link routes and communication fault tolerance, enabling fast recovery capabilities.

1. Transmits signal from Device 1 to Device 3.
2. A fault occurs between Device 2 and Device 3.
3. Notify the fault from Device 2 to Device 1.
4. Transmits signal back from Device 1 to Device 3.

   Flexible Hybrid Structure

• Fiber Optics/Copper Media
• Simple and efficient wiring is available by combining the features of two wires that have advantages and disadvantages.
