LIN Trigger
Selects the trigger mode.
"Start of
Frame"
Triggers on the stop bit of the synchronization field.
"Wake Up"
Triggers after a wakeup frame.
"Error"
Identifies various errors in the frame. You can select one or more
error types as trigger condition.
See
"Error" on page 212.
"Identifier"
Sets the trigger to a specific message identifier or an identifier range.
Only the 6 bit identifier without parity bits is considered, not the pro-
tected identifier.
See
"Identifier condition" on page 212.
"Identifier and
Data"
Triggers on a combination of identifier and data condition. The instru-
ment triggers at the end of the last byte of the specified data pattern.
An example is shown in
Figure 12-27.
See
"Identifier condition" on page 212 and "Data condition"
on page 213.
Remote command:
TRIGger:A:LIN:TYPE on page 420
Error
Select one or more error types as trigger condition.
Checksum ← Error
Triggers on a checksum error. The checksum verifies the correct data transmission. It
is the last byte of the frame response. The checksum includes not only the data but
also the protected identifier (PID).
Remote command:
TRIGger:A:LIN:CHKSerror on page 421
Parity ← Error
Triggers on a parity error. Parity bits are the bits 6 and 7 of the identifier. They verify
the correct transmission of the identifier.
Remote command:
TRIGger:A:LIN:IPERror on page 421
Synchronization ← Error
Triggers if synchronization caused an error.
Remote command:
TRIGger:A:LIN:SYERror on page 421
Identifier condition
The identifier condition consists of the following settings:
●
Identifier value
●
