Port APPLICATION - XCP-CAN-FD-TOLERANT ✦¶

HMS-HW Calibration and Measurement

Provides XCP application access over CAN. CAN-FD messages are tolerated, but the port itself only sends CAN messages.

Stimulation¶

This port has no stimulus capabilities.

Properties 🛈¶

Name	Available if	Default value	Valid values	Type	Description
Channel number		‘1’		string	Selection of channel number if there is more than one controller of same type.
CAN-FD timings		hide details	[show details, hide details] Display values: show details: show details hide details: hide details	string	CAN-FD bit rates and timing parameters – use the graphical editor or check ‘show details’ to work with the individual numbers
TSEG1 ❲Arbitration phase❳	CAN-FD timings: ‘show details’			int	TSEG1 (needed for determining the sample point)
TSEG2 ❲Arbitration phase❳	CAN-FD timings: ‘show details’			int	TSEG2 (needed for determining the sample point)
SJW ❲Arbitration phase❳	CAN-FD timings: ‘show details’			int	Synchronization jump width
Bit rate ❲Arbitration phase❳	CAN-FD timings: ‘show details’			int	In bit/s. Find this value in the CAN-FD A2L file under the name BAUDRATE in the block XCP_ON_CAN.
TSEG1 ❲Data transmission phase❳	CAN-FD timings: ‘show details’			int	TSEG1 (needed for determining the sample point)
TSEG2 ❲Data transmission phase❳	CAN-FD timings: ‘show details’			int	TSEG2 (needed for determining the sample point)
SJW ❲Data transmission phase❳	CAN-FD timings: ‘show details’			int	Synchronization jump width
Bit rate ❲Data transmission phase❳	CAN-FD timings: ‘show details’			int	In bit/s. Find this value in the CAN-FD A2L file under the name CAN_FD_DATA_TRANSFER_BAUDRATE.
Suppress Bit Rate Switching ❲BRS❳		☐		bool	Bit rate switching between arbitration phase and data phase is prevented.
Mode		Standard	[Standard, Extended]	string	Addressing mode (Standard = 11bit, Extended = 29bit)
Listen only		☐		bool	Controller is running in passive mode. Automatic ACK is disabled, and sending CAN frames is not possible.
Receive error frames		☐		bool	Receive error frames
Connection setup		‘OnPortStart’	[‘OnPortStart’, ‘OnPortConfigure’, ‘Job’] Display values: ‘OnPortStart’: ‘At start of test execution’ ‘OnPortConfigure’: ‘At start of configuration’ ‘Job’: ‘manually via job’	string	Time at which the connection to the XCP slave shall be established OnPortConfigure: Online information is available as soon as configurations are started. OnPortStart and Job: Only information from the A2L files is available.
Auto-reconnect		☐		bool	If this option is activated, the connection to the XCP slave is checked once before each read/write operation. If the connection is found to be not alive anymore, an attempt is made to re-establish it. If this succeeds, all buffers are cleared, the last calibration page is re-established, measurements and recordings are continued, and then, the test step is executed. If the reconnect fails, read test-steps return NotPresent while write test-steps are reported as error. Activating this feature might slow down execution of the affected test steps.
Deregister DAQ variables only on disconnect		☐		bool	Registers DAQ variables when the port connection is established. Once DAQ variables are registered, they are available for the entire test execution. After a disconnect, the DAQ variables are unloaded.
Default acquisition rate		‘Tool-Default’		string	Declaration of measurement acquisition rate used as alternative in case no acquisition rate is set in the test step (”*” and “?” can be used as wildcard). “Tool-Default” activates the use of the default acquisition rate of the tool
Skip value validity check		☐		bool	Activate this option in order to suppress the value limit check normally applied on conversion between physical and raw value.
Use seed and key		☐		bool	Define resources to get access permissions for and the file name of the 32-bit dll placed in the tool host path.
Recording mode		‘immediate’	[‘immediate’, ‘two-stage’] Display values: ‘immediate’: ‘immediate’ ‘two-stage’: ‘two-stage’	string	immediate recording writes a signal-based MDF4 file right away during test execution. This mode uses XCP slave timestamps if available. two-stage recording first records raw bus/ethernet traffic and then post-processes it into a signal-based MDF4 file after the test execution is finished. This mode can cope better with a very large number of signals. It uses frame ingress timestamps even if XCP slave timestamps are available. The test case start will be stored as start time in the MDF4 file’s metadata.
Default Polling Cycle [ms]		-1		int	Default polling cycle in milliseconds. All recordings with acquisition rate “Polling” will use this default. This value is used when no polling cycle is provided in the mappings acquisition rate. A value of -1 deactivates the affected polling (however, results from explicit reads in the testcase are still merged into the recording).
XAM file	Deregister DAQ variables only on disconnect: ‘True’			string	All measurement and calibration variables contained in the .xam file are registered for recording and as DAQ variables when the port connection is established. Variables with the same identifier wont be registered twice.
Seed and Key Library Path	Use seed and key: ‘True’	SeedNKeyXcp.dll		uri	Path to the library on the tool host containing the Seed and Key functions. Handling the DLL adds to the configuration start time.
Requested Resources	Use seed and key: ‘True’	5		int	Resources to unlock as bit mask CAL/PAG : 1 CAL/PAG DAQ : 5 CAL/PAG STIM : 9 CAL/PAG PGM : 17 CAL/PAG DAQ STIM : 13 CAL/PAG DAQ PGM : 21 CAL/PAG STIM PGM : 25 CAL/PAG DAQ STIM PGM: 29 DAQ : 4 DAQ STIM : 12 DAQ PGM : 20 DAQ STIM PGM : 28 STIM : 8 STIM PGM : 24 PGM : 16 Duration of the unlocking is dependent on the number of resources.
Transmission confirmation		☐		bool	Activates acknowledged sending. Bus-Write test steps and Send tool jobs block until the message was successfully transferred on the bus or the confirm timeout expired.
Timeout for transmission confirmation		1000		int	Period in miliseconds in which a message has to be sent successfully. Otherwise an error is created. (must not be larger than 64535ms). Is only used in active confirm mode.
CAN-ID Settings		auto	[auto, manual] Display values: auto: auto manual: manual	string	In ‘auto’ mode, the CAN IDs for XCP commands, responses, and DAQ must be specified in the A2L file selected in the TCF. These values will then be used automatically. Choose ‘manual’ mode if you want to specify the command and response IDs yourself, or if any of them are not provided in your A2L file. However, DAQ with CAN IDs that differ from the command and response IDs is currently not supported in mode ‘manual’.
Fill requests to max DLC		☐		bool	If this option is selected the data field of the message is filled to maximum length.
FillByte	Fill requests to max DLC: ‘True’			string	Byte used to fill data field to maximum length. Enter a byte as integer from 0x00 to 0xFF.
CAN-ID ❲Master->Slave❳	CAN-ID Settings: ‘manual’			string	CAN-ID for the direction from ecu.test to the ECU
CAN-ID ❲Slave->Master❳	CAN-ID Settings: ‘manual’			string	CAN-ID for the direction from the ECU to ecu.test
