CAN Bus Signal Analysis Function

2.1

Overview of the CAN Bus Analysis Function

CAN Bus Signal Analysis Function

CAN stands for Controller Area Network. It is a serial communication protocol

standardized internationally by the ISO (International Organization for Standardization).

In communications that use CAN, analysis of the physical layer of the CAN Bus is

required when troubleshooting problems that occur due to noise caused by surge voltage

and level fluctuations caused by excessive load after connection.

By using this function, data can be analyzed while displaying the signal waveforms on

the CAN Bus as analog waveforms. In addition, synchronized monitoring of the data on

the CAN bus and the analog waveform is possible.

The CAN Bus signal analysis function consists of the following four main functions.

Trigger Function <See page 2-5 for the operating procedure>

Acquires CAN Bus signals using the defined frames and fields of the CAN Bus as trigger

conditions. Trigger conditions can be set to SOF, Identifier, Data Field, RTR, or Error

Frame. Triggers can be activated using an AND condition, allowing trigger activation on

frames with specific Identifier and Data Fields.

Triggers can also be activated by combining the trigger conditions of the CAN Bus signal

and the parallel pattern of CH2 to CH8 signal (CH2 to CH4 on the DL7440) (combination

trigger).

Identifier (11 bits)

[Example] For the Standard Format of the Data Frame

S: When Start of Frame is selected for the trigger condition, the Trigger activates here.
I: When Identifier is selected for the trigger condition, the Trigger activates here.

Analysis Function <See page 2-19 for the operating procedure>

Analyzes CAN Bus signal data acquired using the trigger function, and displays the

Identifier, Data Field, and Acknowledge values for each frame in a list. By selecting any

number of frames from this analysis results list, the CAN Bus signals for those frames

can be automatically displayed. Details of the analysis results such as frame and error

types can be viewed in a detailed analysis results list. The data from the detailed

analysis results list can be saved to any storage medium in ASCII format. Also, stuff bits

within the CAN Bus signals can be detected, and stuff bit waveforms can be displayed as

math waveforms. The frames to be analyzed are data frames, remote frames, and error

frames.

Search Function <See page 2-23 for the operating procedure>

After analysis of the CAN Bus signal data acquired using the trigger function, searches

for data matching data from a specific frame or field, and displays the corresponding

waveforms on screen. Searches can also be performed for error frames and frames with

indefinite data. Also, after the search, the beginning of the specified field within the

frame can be displayed (field jump). Using this function, the desired field within the

frame can be instantly displayed.

Cursor Function <See page 2-35 for the operating procedure>

Two cursors can be moved per each CAN Bus bit rate (data transfer rate) while

maintaining a bit rate of space between them. When analyzing or searching, CAN Bus

signal fields and frames can be checked while counting the number of bits.
