If you are not targeted to a real-time (RT) platform, this property is always TRUE. If you are targeted to an RT-platform and the host is connected, this property is TRUE. When this property is FALSE, the host is not connected, requiring that the Real-Time Module application must be able to handle all operations independent of the host. Use this property to determine when it is safe to display a dialog box that requires user interaction.



Version Change(s)
