An instance of this Function Block type provides an implementation of
the Auto/Manual Mode state machine and its associated Lock/Unlock logic
as defined in Annex F.3.2 of the
NORSOK I-005 Standard for System Control Diagrams.
This is implemented as a composite function block type comprising
component instances of the
SCDModeAM and
SCDModeAMLock types, which encapsulate
the mode state machine and Lock/Unlock logic, respectively.
As noted for the SCDModeAMLock type,
this provides a high level of maintainability in case of future
corrections and clarifications in the NORSOK Standard.
