result				ByteStream	ByteStream

DeregisterFrameForInbox

Deregisters a frame that is streamed to the inbox

Parameterization

Parameter

Name	Available if	Default value	Valid values	Type	Description
FrameId				int	Frame ID
Inbox				object	Existing inbox
isExtended		None	[False, True]	bool	Address format: True for 29 bit, False for 11 bit, None uses the setting “Mode” from the test bench configuration

GetFirstValue

Returns the first value of the signal received since the test case started.

Parameterization

Parameter

Name	Available if	Default value	Valid values	Type	Description
FrameName				string	Frame name
NodeName				string	Name of the electronic control unit
RawValue		False	[False, True]	bool	If ‘True’, the Raw value is returned.
Reset		False	[False, True]	bool	If ‘True’ the first received value will be deleted after it has been read
SignalName				string	Signal name

GetLastReceptionTimestamp

Get the last reception timestamp in seconds

InitFrame

Registers the message ID for later use, e.g. ReadFrame

Parameterization

Parameter

Name	Available if	Default value	Valid values	Type	Description
