Using Elemental I/O Property Nodes (WSN)

You can use Elemental I/O Property Nodes to retrieve and set properties programmatically on Elemental I/O items in a LabVIEW project. The properties you can select are specific to the WSN target and the I/O resource that the Elemental I/O item is associated with in the Project Explorer window.

Complete the following steps to create and configure Elemental I/O Property Nodes.

1. Create a new VI or open an existing VI that is under an WSN target that also contains Elemental I/O items.
2. Place an Elemental I/O Property Node on the block diagram.
3. Right-click the Elemental I/O Property Node and select Select Item from the shortcut menu. The Select Item submenu displays the Elemental I/O items present in the Project Explorer window under the WSN target. Select the Elemental I/O item you want to use.
4. Right-click the Property terminal in the Elemental I/O Property Node and select Select Property from the shortcut menu to select a property you want to assign to the Elemental I/O item. LabVIEW displays the properties available for the WSN target in the Select Property submenu. LabVIEW displays No Properties Available in the shortcut menu if the WSN target does not support properties for the Elemental I/O item you select.

   Tip  You also can click the Elemental I/O Property Node and use the shortcut menu to select properties available for the WSN target.

You can add additional Property terminals in the Elemental I/O Property Node by right-clicking the node and selecting Add Element from the shortcut menu. A new Property terminal appears in the Elemental I/O Property Node.

Tip  You also can expand the Elemental I/O Property Node by clicking on the upper or lower edge of the node with the Positioning tool and dragging the edge up or down.
