Figure 109: Window Trace Configuration
How does it Let us first explain the background. Max. 500 values of each Trace Variable
work? can be saved. When the memory is full, sampling starts again from the
beginning. The oldest values are overwritten. If you want to evaluate the
Sampling Trace in peace, for example, you have to stop it so that the values
are not overwritten. That can be done "manually", via the menu, or
automatically by means of the Trigger Variable. If you enter A here, for
example, the next 50% of the values will be sampled after A has changed its
state from 0 to 1. Sampling would then be stopped.
In the example the Trigger Variable is not used. The field remains empty.
The scanning frequency can be selected in multiples of 10 ms. The default
Sample rate
value 0 means scanning in each cycle. Since the cycle time is in the ms range
for the short program, this would be much too fast. Here a scanning frequency
(sample rate) of 100 ms has been selected.
Trace variables To enter the Trace variables in the list, enter them in the bottom field first. Use
<F2>. Double-click on P_AND. and A, B and C are displayed. They are
selected and entered in the list. Since they were defined in the P_AND POU,
the POU name, separated by a dot, is used as a prefix.
In the Input assistant the variables can only be found, in visualisation as well as
in sampling trace, if the project has been compiled once, e.g. with 'Project'
'Rebuild all'.
