  1 Scope
  Scope This part of OPC 10000 defines the Information Model associated with Programs in OPC Unified Architecture (OPC UA). This includes the description of the NodeClasses, standard Properties, Methods ... Events and associated behaviour and information for Programs . The complete AddressSpace model including all NodeClass es and Attributes is specified in OPC 10000-3 . The Services such as those used

  4.2.1 Overview
  Overview Programs are complex Functions in a Server or underlying system that can be invoked and managed by a Client . Programs can represent any level of functionality within a system ... progress monitoring is desired. Figure 2 illustrates the model. Figure 2 - Program illustration Programs are stateful and transition through a prescribed sequence of states as they execute. Their behaviour

  4.2.2 Security considerations
  Security considerations Since Programs can be used to perform advanced control algorithms or other actions, their use should be restricted to personnel with appropriate access rights. It is recommended that ... AuditUpdateMethodEvents are generated to allow monitoring the number of running Programs in addition to their execution frequency

  4.2.4 Program states
  Program states A standard set of base states is defined for Programs as part of the Program Finite State Machine. These states represent the stages in which a Program ... viewed by a Client . This state is the Program's current state. All Programs shall support this base set. A Program may or may not require a Client action

  4.2.10.1 Overview
  Overview Programs can have different lifetimes. Some Programs may always be present on a Server while others are created and removed. Creation and removal can be controlled by a Client ... Program instance. The initial state of the Program can be Halted or Ready . Some Programs , for example, may require that a resource becomes available after its creation and before
