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 inFactoryTalk Optix Studiooccurs at runtime
- AFactoryTalk Optix Studiomethod 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.
Examples
Event | Method |
---|---|
A button is clicked | A PDF report generates |
A variable exceeds a set value | An alarm triggers |
A request from an OPC UA client occurs | A database is queried |
