- Note
- Note 1 to entry: This differs from common language where “subsystem” may mean any sub-divided part of an entity, the term “subsystem” is used in this document within a strongly defined hierarchy of terminology: “subsystem” is the first level subdivision of a system. The parts resulting from further subdivision of a subsystem are called “subsystem elements”. Note 2 to entry: A complete subsystem can be made up from a number of identifiable and separate subsystem elements. Note 3 to entry: The subsystem specification includes its role in the safety function and its interface with the other subsystems of the SCS. Note 4 to entry: One subsystem can be part of several safety functions, e.g. the same combination of contactors can be used to de-energise a motor either in the event of detection of a person in a danger zone or also in the event of opening an interlock guard.
