What is the function of a 'Property Node' in LabVIEW?

The function of a 'Property Node' in LabVIEW is primarily to allow access to properties of controls, indicators, and other objects. Through a Property Node, a developer can read from or write to various properties associated with these objects, enabling dynamic control over their appearance and behavior during runtime.

For example, using a Property Node, you could change the text displayed on a button, modify the value of a numeric control, or alter the color of a graph in real time. This capability enhances the user interface and allows for more interactive applications. The ability to manipulate properties programmatically makes it easier to create responsive designs that adapt based on user interactions or data inputs.

The other options do not accurately describe the essential function of a Property Node. While LabVIEW does allow for executing code based on user input, handling data types dynamically, and creating data clusters, these functions are associated with different components and features within LabVIEW, such as structures, data types, and cluster functions, rather than the specific purpose of a Property Node.
