OPC Controls ListBox Properties

Refer to OPCControls help for all properties and members of the OPC Controls.NET components. All properties can be assigned in code; however no programming is required to use the properties.

Use the SetValueOPCSystems property to enable the ability to write to a Tag Parameter when the ListBox is clicked. If the Tag Parameter is assigned to an OPC Item as a source the OPC Item will be written to with the value specified when the OPC Controls ListBox is clicked.

The following properties can automatically be set by Open Automation Software Tag values.
