This part of IEC 61162 is an add-on to IEC 61162-450 where higher safety and security standards
are needed, for example due to higher exposure to external threats or to improve network integrity.
This document 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 document also contains requirements for a
redundant IEC 61162-460 compliant network.
This document does not introduce new application level protocol requirements to those that are
defined in IEC 61162-450.
