ChassisLogicalAddress Property (VxiBackplaneSession)



Keysight.Visa Namespace > VxiBackplaneSession Class : ChassisLogicalAddress Property
The logical address of a given device in the mainframe (chassis), which serves as a unique ID for the mainframe.
Syntax
'Declaration
 

Public ReadOnly Property ChassisLogicalAddress As Short
'Usage
 

Dim instance As VxiBackplaneSession
Dim value As Short
 
value = instance.ChassisLogicalAddress
public short ChassisLogicalAddress {get;}
public:
property short ChassisLogicalAddress {
   short get();
}
Remarks

The range is between 0 and 255, inclusive.

This is the 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.

Since 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.

The value Ivi.Visa.VisaConstants.VxiUnknownLogicalAddress (-1) indicates that a chassis logical address cannot be determined.

Requirements
