Specify logical address of VXI instrument
For VISA-VXI and VISA-GPIB-VXI objects, you configure LogicalAddress to be the logical address of the VXI instrument. You must include the logical address as part of the resource name during object creation using the visa function.
The Name and RsrcName properties are automatically updated to reflect the LogicalAddress value.
You can configure LogicalAddress only when the object is disconnected from the instrument. You disconnect a connected object with the fclose function. A disconnected object has a Status property value of closed.
This example creates a VISA-VXI object associated with chassis 4 and logical address 1, and then returns the logical address.
vv = visa('agilent','VXI4::1::INSTR'); vv.LogicalAddress ans = 1
