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

OPC Mobile TextBox 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 TextOPCSystemsSendValueOnEnter property to enable the ability to write to a Tag Parameter when the Enter key is selected with the focus of the TextBox.  If the Tag Parameter is assigned to an OPC Item as a source the OPC Item will be written to with the value entered when the OPC Mobile TextBox has received the Enter key event.

Use the TextOPCSystemsDisableUpdateWithFocus property to disable automatic updates to the TextBox when the TextBox has focus.  When the focus is lost the latest received value will be updated to the Text property.

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

BackColor
