Events and methods

An event is a runtime message that indicates that a certain condition has occurred. Events can trigger methods that create application logic.

Method triggers

An object can trigger a method when:
  • An event configured in
    FactoryTalk Optix Studio
     occurs at runtime
  • A
    FactoryTalk Optix Studio
     method called by a C# NetLogic
  • A request from an OPC UA client occurs at runtime
  • A C# method calls at design time or at runtime
TIP: You can associate multiple methods with a single event. When the event occurs, the methods are executed in the order in which they are configured in the event.
