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.
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]).
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.

IEC standards cover a vast range of technologies within electrotechnology. 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 ...
IEC 62351-5 — Security for any profiles including IEC 60870-5 (e.g., DNP3 derivative) TLS for TCP/IP profiles and encryption for serial profiles. IEC 62351-6 — Security for IEC 61850 profiles. VLAN use is made as mandatory for GOOSE; RFC 2030 to be used for SNTP; IEC 62351-7 — Security through network and system management.
