By using DLN LabView Driver Components you are able to get references for modules port, channel and pin. To set and get properties or execute methods we should use Property Node and Invoke Node, which are LabView internal components.
Property Node gets(reads) and/or sets(writes) properties of the reference.
Invoke Node invokes methods or actions. Most methods have associated parameters.
To get these functions, right-click on Block Diagram and navigate to Connectivity > .NET palette. More detailed information on how to use properties and methods can be found at Examples section.
