IVxi3::MainframeLogicalAddress

Note: Keysight's VISA COM does not support a COM server for VXI. The IVxi-related interfaces are listed in this help file because they are included in the global VISA COM library.

Description

Logical address of a given device in the mainframe, usually the device with the lowest logical address.  Other possible values include the logical address of the slot-0 controller or of the parent-side extender.  Often, these are all the same value.  The purpose of this attribute is to provide a unique ID for each mainframe.  A VISA manufacturer can choose any of these values, but must be consistent across mainframes.  If this value is not known, the attribute value returned is UNKNOWN_LA.

VB Prototype
