Finite State Machine

Finite State Machines (FSMs) in OPC UA are special object types that represent states and transitions. In Sterfive OPCUA Modeler, state machines are subtyped from ua:FiniteStateMachineType and configured under the stateMachines section of the YAML file.

This guide explains how to define basic state machines, structure complete production lifecycle models, and promote optional state machine properties to mandatory.

1. Defining a Simple State Machine

A basic state machine is defined by listing its states and the allowed transitions between those states:

Simple state machine definition
stateMachines:
  - browseName: SimpleStateMachineType
    states:
      - name: State1
        value: 0
        description: state 1
      - name: State2
        value: 1
        description: state 2
    transitions:
      - from: State1
        to: State2
        value: 100
      - from: State2
        to: State1
        value: 200

2. Complete Production State Machine Example

A full, industry-grade state machine can contain detailed descriptions, custom components, and initial state markers. Below is a complete ProductionStateMachineType model matching standard industrial lifecycle states (Initializing, Running, Ended, Interrupted, and Aborted):

      possible transitions between those states. 
    subtypeOf: ua:FiniteStateMachineType

        typeDefinition: ua:FiniteStateVariableType
        dataType: ua:LocalizedText
      - browseName: ua:LastTransition
        typeDefinition: ua:FiniteStateTransitionVariableType
        modellingRule: Optional
    states:
      - name: Initializing
        isInitialState: true
        value: 0
        description: |
          **Initializing** is the state in which the element in production is being prepared.
      - name: Running
        value: 1
        description: |
          **Running** indicates that the operation has been started.
      - name: Ended
        value: 2
        description: |
          **Ended** is reached when the production on the part has finished.
      - name: Interrupted
        value: 3
        description: |
          **Interrupted** indicates that the execution has been reversibly halted.
      - name: Aborted
        value: 4
        description: |
          **Aborted** indicates that the operation has been irreversibly stopped.
    transitions:
      - from: Aborted
        to: Initializing
        value: 8
      - from: Ended
        to: Initializing
        value: 2
      - from: Initializing
        to: Aborted
        value: 9
      - from: Initializing
        to: Running
        value: 0
      - from: Interrupted
        to: Aborted
        value: 7
      - from: Interrupted
        to: Running
        value: 5
      - from: Running
        to: Aborted
        value: 6
      - from: Running
        to: Ended
        value: 1
      - from: Running
        to: Interrupted
        value: 4
      - from: Running
        to: Running
        value: 3

Initial States

Setting isInitialState: true marks a specific state as the state in which the machine begins execution when started.

3. Promoting State Machine Optionals to Mandatory

The standard ua:FiniteStateMachineType declares several optional variables (e.g. CurrentState.Name, LastTransition.EffectiveTransitionTime).

You can promote these optional variables to mandatory in your custom state machine so they are automatically instantiated, utilizing the promotedToMandatory property.

Here is a breakdown of the standard optional properties available in ua:FiniteStateMachineType:

Element	Description	ModellingRule
`CurrentState.Name`	Name of the current state	Optional
`CurrentState.Number`	Number of the current state	Optional
`CurrentState.EffectiveDisplayName`	Effective display name of the current state	Optional
`LastTransition.Name`	Name of the last transition	Optional
`LastTransition.Number`	Number of the last transition	Optional
`LastTransition.TransitionTime`	Time of the last transition	Optional
`LastTransition.EffectiveTransitionTime`	Effective time of the last transition	Optional
`AvailableStates`	Available states list	Optional
`AvailableTransitions`	Available transitions list	Optional

A. Promoting Optionals at the StateMachineType Level

To ensure every instance of your state machine type always instantiates these properties, define promotedToMandatory at the state machine type level:

Promoting optionals to mandatory in stateMachineType
stateMachines:
  - browseName: CustomStateMachineType
    subtypeOf: ua:FiniteStateMachineType
    promotedToMandatory:
        - ua:CurrentState.ua:Name
        - ua:LastTransition.ua:Id 
        - ua:LastTransition.ua:TransitionTime

Segment Qualification

Paths in promotedToMandatory: must be segment-qualified. Because CurrentState, Name, etc., are defined in the primary OPC UA namespace, each segment carries the ua: alias (e.g., ua:CurrentState.ua:Name).

B. Promoting Optionals at the Component / Instance Level

Alternatively, you can promote optional state machine properties to mandatory when declaring a component or instance of a state machine inside an ObjectType declaration:

Promoting optionals in instance component declaration
  - browseName: CustomStateHierarchyType
    subtypeOf: ua:FiniteStateMachineType
    promotedToMandatory:
        - ua:AvailableStates
        - ua:AvailableTransitions      
    states:
      - name: Idle
        isInitialState: true
        value: 0
        description: Idle state, initial state of Plc
      - name: Ready
        value: 200
        description: Ready ! Go !
    transitions:
      - from: Idle
        to: Ready
        description: Go Johny Go
      - from: Ready
        to: Idle
        description: Let's have a rest now

objectTypes:
  - browseName: MyComponentType
    subtypeOf: di:ComponentType
    description: A test component
    components:
      - browseName: TheStateMachine
        typeDefinition: CustomStateHierarchyType
        promotedToMandatory:
              - ua:CurrentState.ua:EffectiveDisplayName
              - ua:CurrentState.ua:Name
              - ua:LastTransition
              - ua:LastTransition.ua:TransitionTime
        description: The state of Component

instances:
  - browseName: MyComponent
    typeDefinition: MyComponentType
    organizedBy: /ua:Objects

When your component type is instantiated, all promoted state machine properties will be automatically created on the child StateMachine node.
