RAPIEnet (Real-time Automation Protocols for Industrial Ethernet) is Korea's first Ethernet international standard for real-time data transmission. - An Ethernet-based industrial networking protocol [1] developed in-house by LSIS guarantees real-time transmission and is registered as an international standard.[1] (IEC 61158-3-21: 2010, IEC 61158-4-21: 2010, IEC 61158-5-21: 2010, IEC 61158-6-21: 2010, IEC 61784-2: 2010, IEC 62439-7)
- 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.[1]
- With 100Mbit/s/1Gbit/s transmission speed, electrical and optical media can be used together.[1][2]
- Supports transmission modes such as Unicast, Multicast and Broadcast.[1]
- Supports "Store & Forward”and “Cut Through” switching.[1]

RAPIEnet TechnologyProtocol Stack Structure{{Clear}}Embedded dual port switch motion{{Clear}}- 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.
{{Clear}}Frame Format{{Clear}}- RAPIEnet Ether type: 0x88FE[9]
Topology{{Clear}}{{Clear}}Recovery System- With an embedded switch and full-duplex, it has dual link routes and communication fault tolerance, enabling fast recovery capabilities.
- Recovery time < 10 ms[4] {{Clear}}{{Clear}}- 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{{Clear}}- Fiber Optics/Copper Media
- Copper: Low installation costs with relatively big noise. - Optics: High installation costs with low noise and relatively long wiring. - Simple and efficient wiring is available by combining the features of two wires that have advantages and disadvantages.
