Port BUSACCESS - FLX-OnlineLogging 🛈¶

Access to FlexRay in the test case, with recording on the PC

Stimulation¶

This port supports all features described in Stimulation control.

Properties 🛈¶

Name	Default value	Valid values	Type	Description
Channel number	‘1’		string	Selection of channel number if there is more than one controller of same type.
Bus-DB			string
Placeholder value for automatic E2E calculation			int	Whenever this value is specified for an E2E signal (e.g. CRC), upon transmission ecu.test automatically replaces it with the correct, calculated value. The purpose of this option is to allow transmission of arbitrary fixed values (unequal to the value chosen here). Leaving this option empty completely disables the feature.
Automatic start/stop	‘Test execution’	[‘Test execution’, ‘Configuration start/stop’, ‘Never’]	string	This option affects whether the FlexRay controller will be started and stopped automatically. If ‘Never’ is chosen, the controller must be started and stopped explicitly using the port Job ‘SwitchBusState’. Caution: all timestamps (e.g. in ASC traces) are relative to the time of the controller start.

Parameter

Name	Type	Description
FrameName	string	Frame name
NodeName	string	Name of the electronic control unit
SignalName	string	Signal name

SetFlowControlCTS¶

Activates to always send a Flow Control “ContinueToSend” message in response to a segmented request. Also new values can be assigned to the internal parameters BlockSize, MNPC and SCexp.

Parameter

Name	Type	Description
BlockSize	int	Block size in bytes; maximum number of bytes that may be transmitted in the following consecutive frames before the sender has to wait for another flow control frame. - Integer If None the most recent setting from the test configuration, the OpenDiagSession job or the previous SetFlowControlCTS call is kept.
MNPC	int	MNPC specifies how many consecutive frames the receiver can process within one FlexRay cycle. With MNPC set to 0 the sender can utilize the maximum possible band width. - Integer If None the most recent setting from the test configuration, the OpenDiagSession job or the previous SetFlowControlCTS call is kept.
SCexp	int	SC defines the minimum distance in cycles until the sender is allowed to send the next consecutive frame. SC = 2^SCexp - 1 - Integer If None the most recent setting from the test configuration, the OpenDiagSession job or the previous SetFlowControlCTS call is kept.
SessionId	object	Handle of the diagnostic session. This can be either the name of the SUT specified in the TCF, the handle returned by the OpenDiagSession job or None (can only be used if there is one SUT specified).

SetFlowControlWait¶

Activates to always send a Flow Control “Wait” messages in response to a segmented request. Note: While activated no segmented message can be received. Use the Job SetFlowControlCTS to reset this behaviour.

Parameter

Name	Available if	Default value	Valid values	Type	Description
SessionId				object	Handle of the diagnostic session. This can be either the name of the SUT specified in the TCF, the handle returned by the OpenDiagSession job or None (can only be used if there is one SUT specified).
WaitTimeInterval		0		int	Wait time interval in ms. If set to 0, Flow Control “Wait” messages are only sent once, to respond to a segmented request. If set to a value greater than 0, Flow Control “Wait” messages will be sent periodically with the given interval in between.

SwitchBusState¶

Switches the FlexRay controller on or off.

Caution: switching the controller on will reset the ASC timestamps. Recording during the stop and start of the controller may result in an ASC file which violates the monotony of timestamps.

Parameter

Name	Available if	Default value	Valid values	Type	Description
State		‘Off’	[‘Off’, ‘On’]	string	New state of the bus
