Description
You pass a logical name to the class driver initialization function. MAX must contain an entry for the logical name. The logical name entry refers to a driver session in MAX. The driver session specifies a physical device and a specific instrument driver. By assigning the name of a different driver session to the logical name in MAX, you can swap one instrument for another without changing source code or recompiling or relinking the application program. This attribute returns the logical name you specified when opening the current IVI session.
