Attribute sets of ActiveX object
An ActiveX object has three sets of attributes:
- properties- named characteristics and values of an object such as Value, Enabled, and Caption.
- methods- functions implemented in an ActiveX object that allow external actions to change the object’s appearance, behavior, or properties. A method might be called in response to events from other objects and could trigger other events. In FactoryTalk View, you can use the Invoke command as the external event that calls a method.
- events- actions triggered by an ActiveX object in response to an external action on the object such as a mouse click. You can use events to change the value of a tag or run a FactoryTalk View command or macro. When the event occurs, the command or macro is run. You can also receive parameter values from an event by assigning event parameters to tags.
