View source for IEC 61162

'''IEC 61162''' is a collection of [[Organization:International Electrotechnical Commission|IEC]] standards for "Digital interfaces for navigational equipment within a ship".
The 61162 standards are developed in Working Group 6 (WG6) of Technical Committee 80 (TC80) of the IEC.

==Sections of IEC 61162==
Standard ''IEC 61162'' is divided into the following parts:
* Part 1: Single talker and multiple listeners (Also known as [[NMEA 0183]])<ref>{{cite web|title=Design challenges and decisions for a new ship data network|url=http://www.mits-forum.org/resources/lwe-paper-isis-v9.pdf|access-date=6 January 2017}}</ref>
* Part 2: Single talker and multiple listeners, high-speed transmission
* Part 3: Serial data instrument network (Also known as [[Engineering:NMEA 2000|NMEA 2000]])
* Part 450:  Multiple talkers and multiple listeners–Ethernet interconnection (Also known as Lightweight Ethernet)
* Part 460:  Multiple talkers and multiple listeners - Ethernet interconnection - Safety and security
 
The 61162 standards are all concerning the transport of NMEA sentences, but the IEC
does not define any of these. This is left to the [http://www.nmea.org/ NMEA Organization].

==IEC 61162-1==
Single talker and multiple listeners.

==IEC 61162-2==
Single talker and multiple listeners, high-speed transmission.

==IEC 61162-3==
Serial data instrument network, multiple talker-multiple listener, prioritized data.

==IEC 61162-450==
Multiple talkers and multiple listeners.

This subgroup of TC80/WG6 has specified the use of Ethernet for shipboard navigational networks. The specification describes the transport of NMEA sentences as defined in 61162-1 over IPv4. Due to the low amount of protocol complexity it has been nicknamed Lightweight Ethernet or LWE in short.

The historical background and justification for LWE was presented at the ISIS2011 symposium.<ref>Ø.J. Rødseth, et al. "Overview of the IEC 61162-450 “Light Weight Ethernet” Ship Bridge Data Network", ISIS2011</ref> An overview article of LWE was
given in the December 2010 issue of "Digital Ship"<ref>M.J. Christensen, et al. ''Lightweight Ethernet - a new standard for shipbord networks" [http://issuu.com/mortenjc/docs/digital_ship_december_2010]''</ref>

The standard was published in the first edition in June 2011.  The second edition is in progress (state May 2016).

==IEC 61162-450/460==
IEC 61162-460:2015(E) is an add-on to the IEC 61162-450 standard where higher safety and security standards are needed, e.g. due to higher exposure to external threats or to improve network integrity. This standard provides requirements and test methods for equipment to be used in an IEC 61162-460 compliant network as well as requirements for the network itself and requirements for interconnection from the network to other networks. This standard also contains requirements for a redundant IEC 61162-460 compliant network. This standard extends the informative guidance given in Annex D of IEC 61162-450:2011. It does not introduce new application level protocol requirements to those that are defined in IEC 61162-450. 

The first edition was published in August 2015.

State May 2016 is the first bridge and system manufacturers beginning with the implementation of IEC 61162-450 and IEC 61162-460.
