IEC 61162

IEC 61162 is a collection of 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 four parts:

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 NMEA Organization.

IEC 61162-1

Single talker and multiple listeners is an international standard

IEC 61162-2

Single talker and multiple listeners, high-speed transmission

IEC 61162-3

Serial data instrument network

IEC 61162-450

Multiple talkers 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.[1] An overview article of LWE was given in the December issue of "Digital Ship" [2]

The standard was published in the first edition 06/2011 . The second edition is in progress(state 05/2016).

IEC 61162-460

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 08/2015.
