Figure 20: Statistics Report
Besides showing the total number of messages for each identifier, the statistics report
also shows the mean value, standard deviation, and minimum and maximum for the
recorded transmit interval.
Another bus-related window, the Bus Statistics window, provides an overview of bus
data traffic. Displayed here are the total frequencies of data, remote, error and overload
frames, bus loading and CAN controller status. Since in our case one message
is sent every 100 ms and the second message every 200ms, the total frequency of all
messages is 15 frames per second. With an average data length of about 70 bits per
frame, approx. 15 * 70 ≈ 1000 bits are placed on the bus in one second. At a baud
rate of 100 kBit/sec the bus load in our example would be on the order of magnitude
of one percent.

Before we discuss the remaining windows in detail, let us have a look at the capabilities
offered by CANoe for the symbolic description of data. Of primary interest in the
