Configure a change event

Configure a change event

Trigger methods if the value of a variable or object property changes.
TIP: If you use a controller tag in a change event, the tag always updates at runtime, even if the
FactoryTalk Optix Application
 does not display the tag value.
  1. In
    Project view
    , select an object or a variable.
  2. In
    Properties
    , right-click a variable or a property and select
    New
    Changed event
    .
    TIP: If needed, select
    Add
     to add a variable.
  3. In
    Events
    , next to
    VariableChanged
    , select
    Add
    .
  4. Select a method:
    • For global methods, expand
      Commands
      .
    • For local methods, expand the nodes that expose methods (for example, a
      DataGrid
       node exposes a
      Refresh
       method), or expand the node related to a specific NetLogic.
  5. (optional) If the method requires arguments, expand the method and set arguments.
  6. (optional) Select more methods by repeating 3 through 5.
