XNET Session

nxPropSession_Protocol

This property returns the protocol that the interface in the session uses.

The values (enumeration) for this property are:

0	CAN
1	FlexRay
2	LIN
3	Ethernet

Data Type	Direction	Required?	Default
u32	Read Only	No	N/A

XNET Interface

nxPropIntf_DevRef

From the XNET Interface handle, this property returns the XNET device handle.

The XNET device handle returned is the physical XNET board that contains the XNET interface. This property determines the physical XNET device through the XNET Device Serial Number property for a given XNET Interface handle.

Data Type	Direction	Required?	Default
string	Read/Write	Yes	Defined in nxdbCreateObject

XNET LIN Schedule Entry

nxPropLINSchedEntry_Name

String identifying the LIN schedule entry object.

Lowercase letters (a–z), uppercase letters (A–Z), numbers, and the underscore (_) are valid characters for the short name. The space ( ), period (.), and other special characters are not supported within the name. The short name must begin with a letter (uppercase or lowercase) or underscore, and not a number. The short name is limited to 128 characters.

A schedule entry name must be unique for all entries in the same schedule.

XNET Interface

nxPropIntf_Num

Returns unique number associated with the XNET interface.

The XNET driver assigns each port connector in the system a unique number XNET driver. This number, plus its protocol name, is the interface name string. For example:

XNET Interface String Name	Number
CAN1	1
FlexRay3	3

Data Type	Direction	Required?	Default
u32	Read Only	No	N/A

XNET Interface

nxPropIntf_PortNum

Returns the physical port number printed near the connector on the XNET device.

The port numbers on an XNET board are physically identified with numbering. Use this property, along with the XNET Device Serial Number property, to associate an XNET interface with a physical (XNET board and port) combination.

Note  It is easier to find the physical location of an XNET interface with nxBlink.

XNET Interface

nxPropIntf_CANTcvrCap

Returns an enumeration indicating the CAN bus physical transceiver support.

Enumeration	Value
High-Speed/Flexible Data-Rate (HS/FD)	0
Low-Speed/Fault-Tolerant (LS/FT)	1
XS (HS/FD, LS/FT, SW, or External)	3
XS (HS/FD, LS/FT)	4

The XS value in the enumeration indicates the board has multiple physical transceivers that you can configure in software. XS may support High-Speed and Flexible Data-Rate (HS/FD), Low-Speed Fault-Tolerant (LS/FT), Single Wire (SW), or can connect to an external transceiver. This value is switchable through the XNET Session Interface:CAN:Transceiver Type property.

u32	Read Only	No	N/A

XNET Interface

nxPropIntf_CANTermCap

Returns an enumeration indicating whether the XNET interface can terminate the CAN bus.

Enumeration	Value
No	0
Yes	1

Signal reflections on the CAN bus can cause communication failure. To prevent reflections, termination can be present as external resistance or resistance the XNET board applies internally. This enumeration determines whether the XNET board can add termination to the bus.

To select the CAN transceiver termination, refer to XNET Session Interface:CAN:Termination.

XNET Interface

nxPropIntf_DongleState

Returns an enumeration indicating the connected Transceiver Cable's state.

Description	State	Value
No dongle, no external power	nxDongleState_NoDongle_NoExtPower	1
No dongle, has external power	nxDongleState_NoDongle_ExtPower	2
Has dongle, no external power	nxDongleState_Dongle_NoExtPower	3
Ready	nxDongleState_Ready	4
Busy	nxDongleState_Busy	5
Comm error	nxDongleState_CommError	13
Overcurrent	nxDongleState_OverCurrent	14

Some Transceiver Cable types require external power from the network connector for operation. Refer to the hardware-specific manual for more information.

XNET Interface

nxPropIntf_DongleID

Returns an enumeration indicating the connected Transceiver Cable's type.

Type	ID
CAN High Speed (HS)	2
CAN Software-Selectable (XS)	4
LIN	6
Dongle-Less Design	13
Unknown	14

Dongle-Less Design indicates this interface is not a Transceiver Cable but a regular XNET expansion card, cDAQ Module, and so on.

XNET Interface

nxPropIntf_DongleRevision

Returns the connected Transceiver Cable's hardware revision number.

Data Type	Direction	Required?	Default

XNET Interface

nxPropIntf_DongleFirmwareVersion

Returns the connected Transceiver Cable's firmware revision number.

Data Type	Direction	Required?	Default
u32	Read Only	No	N/A

XNET Interface

nxPropIntf_DongleCompatibleRevision

Returns a number representing the oldest driver version compatible with the connected Transceiver Cable's hardware revision. The number is relative to the first driver version that supported the particular Transceiver Cable model, starting with 1 for the original revision.

A Transceiver Cable hardware revision might require a later XNET driver than the version that introduced support for this model for operation.

XNET Interface

nxPropIntf_DongleCompatibleFirmwareVersion

Returns a number representing the oldest driver version compatible with the connected Transceiver Cable's firmware. The number is relative to the first driver version that supported the Transceiver Cable, starting with 1 for the original revision.

A Transceiver Cable running an updated firmware version may require a later XNET driver than the version it shipped with for operation.
