val at which the display is refreshed. Averaging is most precise with a low value, but
this demands a lot of computing time. With high values the statistics display lags behind.
An averaging time of approx. 1000 ms gives satisfactory results for standard
applications.
Figure 66: Configuration of the Statistics Block
In standard mode the messages of the channels are displayed side by side. In tab
view mode the window is split. In the left part (standard view) the messages are
shown. In the right part (special view) special events are shown, e.g. error frames.
With the tabs on the bottom of the window you can switch between the buses. You
can have up to 3 standard views but only one special view for each bus channel.
You can scale the Statistics window from the popup menu. The functions available for
this, such as Zoom, Fit, Basic Image and Manual Scaling are described in detail in
online Help.
Note: If the CAN card used supports extended identifiers, the function Basic
Image is split. The user can choose whether scaling will be over the range
of standard identifiers or over the entire range.
3.7.2 Statistics Report
In background, statistics are kept on all bus actions, and the results can be reported
to the Write window after conclusion of the measurement. A list is constructed (sorted
by message identifiers) which contains information organized separately for receive
messages, transmit messages, transmit requests and transmit delays: Number of
messages, mean time spacing, standard deviation, minimum spacing, maximum
spacing.
When you select the option Activate under Expanded statistical functions in the
statistics configuration dialog all data will be accumulated for the report. However,
this of course requires computer resources and can slow down very fast bus traffic.
You can output the statistics report to the Write window either automatically or via the
menu entry Display statistics report after the end of a measurement.
