Help Center - CANoe

The Bus Statistics window provides an at-a-glance view of the bus CANoe is connected to.  It provides valuable information pertaining to the rate at which messages are received, how loaded down the bus is, and a first alert to bus errors.



What do I see?

Within the Bus Statistics window is a column for each bus channel being used in the configuration.  For each channel, different data points are displayed as numeric values; either a percentage, a rate or receipt, or a total value.

The data points collected are as follows:

• Busload
• Peakload
• Data Frames
  - Standard
  - Extended
  - Remote
• Error Frames
• Chip state

How is it configured?

The only setting for the Bus Statistics window is the font.  This can be changed by right-clicking in the Bus Statistics window and selecting “Font”.

How many can I have?

Only one Bus Statistics window can be used in a CANoe configuration.

What is the chip state?

Chip state refers to the state of the CAN controller on the CAN hardware (ex CANcardXL).  There are three states:

• Active - The active state is the normal operating state.
• Passive - The passive state occurs when either the transmit or receive error counter reaches 128.
• Off - The chip state goes to off when the transmit error counter reaches 256.

The chip state is determined by the number of error frames transmitted or received.  Each channel has separate transmit and receive counters.

What if I don’t use remote frames?

To remove the remote frames headings from the Bus Statistics window, it will be necessary to make a change to the CAN.INI file.  This file contains control settings for CANoe and should not be changed unless necessary.

Open the CAN.INI file in a text editor like Notepad, and scroll to this entry:

[Busstatistic]
; display statistics for remote frames (1=on/0=off)
remote=1

Change the 1 to a 0 to remove the remote frames entry in the window.  If CANoe is currently running, close and reopen to apply the new settings.

What if I have multiple bus types?



If multiple bus types are being used in the same configuration (ex LIN), at least 2 new columns will be added: 1 column for the new data points registered, and 1 column for the bus channel itself.
