The OPC Mobile NumericUpDown component performs exactly like the standard Device NumericUpDown component with additional properties to automatically update from any remote OPC Systems Tag Parameter.

OPC Mobile NumericUpDown Properties

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

Use the ValueOPCSystemsSetValue property to enable the ability to write to a Tag Parameter when the NumericUpDown value is changed.  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 Mobile NumericUpDown value is changed.

The following properties can automatically be set by OPC Systems Tag values.
