3.6.5.3 Select Trace
This dialogue is invoked from the View Trace form by selecting the Trace | Select from TC menu option
and is used for selecting one or several traces to display.
The list shows traces stored. By use of the
Show traces for…
frame you can select which traces to show.
In the ID field write as many characters you like. All traces that have an ID that contains the string of
characters will be displayed.
Hold down the CTRL key and select with the mouse the traces you are interested in. When you return to
the view window all the traces are presented in the same diagram, with different colors.
Normally traces are from the most recent cycles. Traces, that are tagged for save, will be saved
indefinitely. The save tag can be switched on and off by use of the
Save/Unsave buttons for any trace.
Saved traces are marked by an S in the Save column on the left side of the window.
Due to the fact that traces consume quite a lot of memory only a limited number of traces can be saved.
When trace memory is full and new traces are produced the system will strive to keep the number of
stored OK and NOK according to the SRAM configuration (see chapter SRAM). This means that a new
OK trace will overwrite the oldest OK trace not marked for save, and vice versa for NOK traces.
Note!
All traces, also the ones marked for “Save”, are deleted if the battery backed up memory is cleared,
for example when new System Software is loaded.
