  F.2 SystemStateStateMachineType
  SystemStateStateMachineType The SystemStateStateMachineType includes a hierarchy of sub-states. It supports multiple transitions between Operating, StartingUp, ShuttingDown, Shutdown, OutOfService and Maintenance. The state machine is illustrated in Figure ... HasComponent Method OutOfServiceShutdown Defined in Clause XXX Optional The actual selection of States and Transitions would depend on the deployment of the StateMachine . If the StateMachine were being applied

  4.3 Definition of state machine
  semantics specified by the type. For some types, this means that the states and transitions are fixed. For other types the states and transitions may be dynamic or unknown ... FiniteStateMachineType . The StateMachineType specifies a description of the state machine, that is, its states, transitions, etc., whereas the StateMachine is an instance of the StateMachineType and only contains the current

  4.4.6 FiniteStateMachineType
  FiniteStateMachineType is the base ObjectType for StateMachines that explicitly define the possible States and Transitions . Once the States and Transitions are defined subtypes shall not add new States and Transitions ... State is the State that the machine goes into when it is activated. The Transitions that may occur are represented with instances of the TransitionType . Each Transition shall have

  4.4.11 TransitionType
  TransitionType Transitions of a FiniteStateMachine are represented as Objects of the ObjectType TransitionType formally defined in Table 11 . Each Object of the TransitionType or one of its subtypes shall

  4.4.19 Special Restrictions on subtyping StateMachines
  StateMachine types as well. Some additional rules apply for StateMachine types. States and Transitions are not instantiated, this information is only provided on the ObjectType . They have no ModellingRule ... thus, also the inheritance of States and Transitions is not defined. Therefore, the following rules apply for subtyping StateMachines . Each State and Transition defined on the supertype shall be available

  4.5.4 Example of a StateMachine having Transition to SubStateMachine
  StateMachine having Transition to SubStateMachine The StateMachines shown so far only had Transitions between States on the same level, that is, on the same StateMachine . Of cause, it is possible ... often required to have Transitions between States of the StateMachine and States of its SubStateMachine . Because a SubStateMachine can be defined by another StateMachineType and this type can be used

  4.6.2 ChoiceStateType
  state that is directly exited when it is entered. The Guards defined on the Transitions from the ChoiceState determine which Transition is used. The Guards shall be defined ... false". If several Guards are "true", only one of those Transitions is used. The algorithm to determine the Transition is server-specific. A sample StateMachine using

  12.3 MaintenanceEventStateMachineType
  actions of the MaintenanceEventStateMachineType, the execution of the StateMachine is server-specific. The Transitions go from Planned to Executing to Finished. In case or repeating maintenance activities, the StateMachine might
