High-availability Seamless Redundancy (HSR) is a network protocol for Ethernet that provides seamless failover against failure of any single network component. PRP and HSR are independent of the application-protocol and can be used by most Industrial Ethernet protocols in the IEC 61784 suite.
iec 61784-2, iec 61158 Profinet (usually styled as PROFINET , as a portmanteau for Pro cess Fi eld Net work) is an industry technical standard for data communication over Industrial Ethernet , designed for collecting data from, and controlling equipment in industrial systems , with a particular strength in delivering data under tight time ...
A fieldbus is a member of a family of industrial digital communication networks [1] used for real-time distributed control. Fieldbus profiles are standardized by the International Electrotechnical Commission (IEC) as IEC 61784/61158.
openSAFETY is certified according to IEC 61508 [1] and meets the requirements of SIL 3 applications. The protocol has been approved by national IEC committees representing over two dozen countries around the world, and has been released for international standardization in IEC 61784-3 FSCP 13.
This is in contrast to the companion standard HSR (IEC 62439-3 Clause 5), with which PRP shares the operating principle. PRP and HSR are independent of the application-protocol and can be used by most Industrial Ethernet protocols in the IEC 61784 suite. PRP and HSR are standardized by the IEC 62439-3:2016 [1]).
IEC 113 (Superseded by IEC 750, i.e. IEC 60750.) IEC 750-1983 (AS 3702 is equivalent, but provides extra information.) IEEE 315-1975 / ANSI Standard Y32.2. Annex F: "Cross reference list of Class Designation Letters" compares IEC 113-2:1971 to the IEEE/ANSI standard. * AS 1102 and IEC 60617 for "Graphical Symbols for Electrotechnology".
The first version of Profisafe was released as early as 1998. [4] A second version in 2005 also enabled use via the Ethernet-based Profinet. According to the PROFIBUS Nutzerorganisation e.V., by 2023 a total of almost 21,7 million devices with Profisafe will be placed on the market by the various manufacturers, and a further 2.8 million devices will be added each year.

The numbers of older IEC standards were converted in 1997 by adding 60000; for example IEC 27 became IEC 60027. IEC standards often have multiple sub-part documents; only the main title for the standard is listed here. IEC 60027 Letter symbols to be used in electrical technology; IEC 60028 International standard of resistance for copper
