'''RAPIEnet''' ('''Real-time Automation Protocols for Industrial Ethernet''') was [[Korea]]'s first [[Ethernet]] international standard for real-time data transmission. It is an Ethernet-based industrial networking protocol,<ref name="4-21">[http://webstore.iec.ch/preview/info_iec61158-4-21%7Bed1.0%7Den.pdf IEC 61158-4-21: 2010]</ref> developed in-house by LSIS offers real-time transmission and is registered as an international standard.<ref>[http://www.upkorea.net/news/articleView.html?idxno=19909 RAPIEnet related articles]</ref> (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)

== Features ==
*An embedded [[Network switch|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.<ref name="4-21" />
*100 Mbit/s - 1 Gbit/s transmission speed, allowing electrical and optical media to be used together.<ref name="4-21" /><ref>[http://webstore.iec.ch/preview/info_isoiec8802-3%7Bed6.0%7Den.pdf ISO/IEC 8802-3: 2000]</ref>
*Supports transmission modes such as [[Unicast]], [[Multicast]], and [[Broadcasting|Broadcast]].<ref name="4-21" />
*Supports "[[Store and forward|Store & Forward]]”and “[[Cut-through switching|Cut Through]]” switching.<ref name="4-21" />

===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<ref name="4-21" />

#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
: - 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.
