5.1 General

Each Program has a Type Definition that is the subtype of the FiniteStateMachineType. The ProgramStateMachineType describes the Finite State Machine model supported by any Program Invocation of that type ... ProgramStateMachineType also defines the property set that characterizes specific aspects of that Program's behaviour such as lifetime and recycling as well as specifying the result data that is produced

5.2.2 ProgramStateMachineType Properties

ProgramStateMachineType Properties The Creatable Property is a boolean that specifies if Program Invocations of this ProgramStateMachineType can be created by a Client . If False, these Program Invocations are persistent ... Deletable Property is a boolean that specifies if a Program Invocation of this ProgramStateMachineType can be deleted by a Client . If False, these Program Invocations can only be deleted

5.2.3.1 Overview

Overview The ProgramStateMachineType components consist of a set of References to the Object instances of StateTypes , TransitionTypes , EventTypes and the Methods that collectively define the Program FiniteStateMachine. Figure 5 - Program ... Figure 5 illustrates the component References that define the associations between two of the ProgramStateMachineType's states, Ready and Running. The complementary ReferenceTypes have been omitted to simplify the illustration

5.2.3.2 ProgramStateMachineType states

ProgramStateMachineType states The state Objects are instances of the StateType defined in OPC 10000-16 . Each state is assigned a unique StateNumber value defined in Table 6 . Subtypes ... ProgramStateMachineType can add references from any state to a subordinate or nested StateMachine Object to extend the FiniteStateMachine . The Halted state is the idle state for a Program

5.2.4.1 Overview

Overview The ProgramStateMachineType includes references to the Causes of specific Program state transitions. These causes refer to Method instances . Programs that do not support a Program Control Method will omit ... Causes reference to that Method from the ProgramStateMachineType references. If a Method's Causes reference is omitted from the ProgramStateMachineType then a Client cannot cause the associated state transition
