5.4.3 HasFalseSubState ReferenceType ToC Previous Next index

The HasFalseSubState ReferenceType is a concrete ReferenceType that can be used directly. It is a subtype of the NonHierarchicalReferences ReferenceType.

The semantics indicate that the sub state (the target Node) is a subordinate state of the False super state. If more than one state within a Condition is a sub state of the same super state (i.e. several HasFalseSubState References exist for the same super state) they are all treated as independent sub states. The representation in the AddressSpace is specified in Table 6.

The SourceNode of the Reference shall be an instance of a TwoStateVariableType and the TargetNode shall be either an instance of a TwoStateVariableType or an instance of a subtype of a StateMachineType.

It is not required to provide the HasFalseSubState Reference from super state to sub state, but it is required that the sub state provides the inverse Reference (IsFalseSubStateOf) to its super state.
