Explanation
This function triggers on CAN bus signals. For details on the CAN bus signal frame
format, see page 6-65.
Note that the /F7 or /F8 option is requied for analysis of CAN bus signals.
Mode
Set the CAN trigger mode to SOF, Error Frame, ID Std/Data, ID Ext/Data, ID/Data OR, or
Msg/Signal.
SOF Mode
Triggers on the start of a CAN bus signal frame.
SOF: Start of Frame
Error Frame Mode
The DL9000 triggers when the error frame’s error flag is active.
ID Std/Data and ID Ext/Data Modes
ID Std/Data mode is used to trigger on the data frame or remote frame in standard
format.
ID Ext/Data mode is used to trigger on the data frame or remote frame in extended
format.
The DL9000 triggers on the AND logic of ID, Frame Type, Data, and ACK conditions.
The settings in ID Std/Data mode are shared with the settings in ID Ext/Data mode.
• ID
Set the ID bit pattern in hexadecimal or binary notation.
The ID bit pattern is 11 bits in
standard format and 29 bits in extended format.
The ID trigger condition is met when
the specified bit pattern matches the input signal ID bit pattern.
• If you specify X, the condition is assumed to be met regardless of the corresponding bit
status.
• If a binary pattern contains any Xs, the corresponding hexadecimal display will be “$.”
• Frame Type
The DL9000 can be configured to trigger on the remote frame or data frame.
• Selecting the Frame
A
CAN bus signal frame contains a Remote Transmission Request (RTR) bit that
indicates whether the frame is a remote frame or a data frame. Select the frame
that the DL9000 will trigger on.
Don’t care The DL9000 will trigger on both remote frames and data frames.
Remote The DL9000 will trigger on remote frames.
Data Frame The DL9000 will trigger on data frames.
If you select Don’t care or Remote, the DLC and Data trigger conditions in the next section
will be ignored.
• DLC (Data Length Code)
Set the data field length. The DLC trigger condition is met when the input signal
DLC value matches the reference value. Set this value only when the frame type is
set to Data Frame.
Selectable range: 0 to 8 bytes
If you set this value to zero, the data trigger conditions in the next section will be ignored.
