ing. However, to obtain reasonable outputs in the Data window you should not select
a cycle time greater than 500 ms.
3.7 Statistics Window
115
The Statistics block fulfills three different functions. One of these is to display the
average time between the sending of messages (secs/msg) during a measurement.
It can also display the messages per second. These are done by constructing a continuously
updated line histogram above a message identifier’s axis. A sliding scale
averaging method with an adjustable averaging time is used. The other function
keeps statistics on all bus activities in the background; these results can be reported
either as a statistical report in the Write window or stored via a histogram function
and then processed further.
Figure 65: Statistics Window
The Statistics window displays (see Figure 65) the mean message rates existing at
the end of the measurement. The Write window contains the statistics report (see
Figure 67).
3.7.1 Direct Display in the Statistics Window
During the measurement either the mean transmit interval or the mean message rate
is displayed in the Statistics window. Smoothed averaging is used with adjustable
averaging time. The message identifiers are output on the horizontal axis, and the
corresponding rates on the vertical axis. The IDs are distributed according to whether
they originated from controller CAN1 or CAN2, and by message attributes Rx and Tx:
Rx Tx
CAN1 RED BLUE
CAN2 RED BLUE
In the statistics configuration dialog you can define whether the window diagram
should show the mean transmit interval (sec/msg) or its inverse, the mean message
rate (msg/sec). Also configurable is the averaging time which defines the time inter-
