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:
Part 1: Single talker and multiple listeners (Also known as NMEA 0183)
Part 2: Single talker and multiple listeners, high-speed transmission
Part 3: Serial data instrument network (Also known as 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 securityThe 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.
An overview article of LWE was given in the December issue of "Digital Ship"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.
