RAPIEnet
RAPIEnet was Korea's first Ethernet international standard for real-time data transmission. It is an Ethernet-based industrial networking protocol, developed in-house by LSIS offers real-time transmission and is registered as an international standard.
Features
- 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.
- 100 Mbit/s - 1 Gbit/s transmission speed, allowing electrical and optical media to be used together.
- Supports transmission modes such as Unicast, Multicast, and Broadcast.
- Supports "Store & Forward”and “Cut Through” switching.
RAPIEnet Technology
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
Recovery System
- With an embedded switch and full-duplex, it has dual link routes and communication fault tolerance, enabling fast recovery capabilities.
- Transmits signal from Device 1 to Device 3.
- A fault occurs between Device 2 and Device 3.
- Notify the fault from Device 2 to Device 1.
- 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.
