Elemental IO Node

Owning Palette: Elemental I/O Functions

Requires: LabVIEW WSN Module

Performs specific Elemental I/O operations on WSN targets. You can configure the Elemental I/O Node with one or more Elemental I/O items. Elemental I/O resources can perform both read and write operations.

To add Elemental I/O items to an Elemental I/O Node, right-click the I/O Item section and select Add Element from the shortcut menu. You also can expand or contract the Elemental I/O Node by clicking the upper or lower edge of the node with the Positioning tool and dragging the edge up or down.

Details  

I/O Item is the data read from or written to the Elemental I/O item you specify. For Elemental I/O items that support the read operation, this parameter is an indicator. For I/O items that do not support the read operation, this parameter is a control. For Elemental I/O items that support reading and writing, this parameter can be either a control or an indicator.

Elemental IO Node Details

When you right-click the I/O Item terminal of the Elemental I/O Node and select Select Elemental I/O from the shortcut menu, LabVIEW displays the Elemental I/O items that appear in the Project Explorer window below the same WSN target as the VI you are currently editing. You also can right-click the I/O Item terminal and select Add New Elemental I/O from the shortcut menu to add new Elemental I/O items under the WSN target.

Digital input and output (DIO) resources can perform both read and write operations. To change the operation of an Elemental I/O item, right-click the element and select Change to Read or Change to Write from the shortcut menu.

When you configure an Elemental I/O Node with multiple I/O items, the execution timing of the I/O items depends on the specific hardware devices and I/O items you use. Some Elemental I/O operations execute in parallel, while others execute sequentially.

Tip  Right-click an element in the Elemental I/O Node and select Find Elemental I/O in Project from the shortcut menu to highlight the Elemental I/O item in the Project Explorer window.
