Interface IPxi

Description

The IPxi base interface defines the methods and COM properties specific to PXI INSTR sessions.

IPxi derives from IVisaSession.

Note: Programming is identical for PXI, PXIe and PCIe device types. The term PXI is used in this document to represent all three device types.

Methods

GetAttribute	Use of this method is discouraged. All the non-deprecated standard attributes are accessible via properties on the appropriate COM interfaces.
SetAttribute	Use of this method is discouraged. All the non-deprecated standard attributes are accessible via properties on the appropriate COM interfaces.
Close	Closes the resource. Sending the resource's COM object's reference count to zero (and thus destroying the object) also executes a close, but this method may be useful for environments with garbage collection or other facilities that make object lifetimes non-deterministic.
Init	Opens the resource. This is the first method on IVisaSession or any of its derived interfaces to be called. In general, you will not call this method because you will use the Resource Manager to create resources.
LockRsrc	Locks the resource.
UnlockRsrc	Unlocks the resource

Properties

ActualLinkWidth	Returns the negotiated link width.
BusNumber	Returns the PCI bus number.
ChassisNumber	Returns the chassis number.
ComponentVersion	Returns the implementation version of the component.
DevNumber	Returns the PCI device number.
DstarBusNumber	Returns the differential star bus number.
DstarLineSet	Returns the connected set of PXI Express differential star bus lines.
FuncNumber	Returns the PCI function number.
HardwareInterfaceName	Get a description of the hardware interface.
HardwareInterfaceNumber	Returns the hardware interface number.
HardwareInterfaceType	Returns the hardware interface type.
IsExpress	Get whether the device is PXI Express.
LastStatus	The return value from the last method call on this interface. This property may be useful in Visual Basic, where positive return values, such as warnings and other non-error return values, cannot be retrieved. See the Return Values page for a list of positive return values.
LockState	The current locking state of the interface.
MaxLinkWidth	Returns the current lock state of the resource.
MemBaseBar0	Returns the memory base address for BAR 0.
MemBaseBar1	Returns the memory base address for BAR 1.
MemBaseBar2	Returns the memory base address for BAR 2.
MemBaseBar3	Returns the memory base address for BAR 3.
MemBaseBar4	Returns the memory base address for BAR 4.
MemBaseBar5	Returns the memory base address for BAR 5.
MemSizeBar0	Returns the memory size for BAR 0.
MemSizeBar1	Returns the memory size for BAR 1.
MemSizeBar2	Returns the memory size for BAR 2.
MemSizeBar3	Returns the memory size for BAR 3.
MemSizeBar4	Returns the memory size for BAR 4.
MemSizeBar5	Returns the memory size for BAR 5.
MemTypeBar0	Returns the memory type used in BAR 0.
MemTypeBar1	Returns the memory type used in BAR 1.
MemTypeBar2	Returns the memory type used in BAR 2.
MemTypeBar3	Returns the memory type used in BAR 3.
MemTypeBar4	Returns the memory type used in BAR 4.
MemTypeBar5	Returns the memory type used in BAR 5.
OptionString	Returns the current state of all settable properties.
ProgID	Returns the programmatic ID that can be used by COM to create this object.
ResourceName	Returns the VISA resource name of the currently open resource. This name is the canonical version of the resource name and therefore may vary from the resource string used to open/init the resource.
SessionType	Returns the session type string, such as "INSTR" or "INTFC".
SlotLinkWidth	Returns the link width used by the slot.
SlotLocalBusLeft	Returns the slot number or special feature connected to local left bus lines.
SlotLocalBusRight	Returns the slot number or special feature connected to local right bus lines.
SlotPath	Returns the slot path.
SoftwareManufacturerID	The ID number of the vendor of this software component.
SoftwareManufacturerName	The name of the vendor of this software component.
SpecVersion	The VISA-defined version information for the specification version to which this component complies.
StarTriggerBus	Returns the PXI star trigger bus.
StarTriggerLine	Returns the connected PXI star line.
Timeout	Get or set the I/O timeout in milliseconds for I/O communication on this resource session.
TriggerBus	Returns the trigger bus number of this device.
