## **Read Instancified Objects**
How to read an instancified object’s data.

Click Item.


Click GetItemInstance to see Item’s ID and attribute’s name and value.


p.s. When an Object is not instancified, the suggestion is to execute the “object-instancifying” example first. And then, learn to read instancified objects. In this example, for an Object that is not instancified, even when the code is 0, it will be returned in CallBack. Please pay extra attention to this.
