'Extras' 'Stop Trace'
Symbol:
This command stops the Sampling Trace in the PLC.
8.12.3 Looking at the trace sampling
Display of the Sampling Trace
Sampling Trace of Different Variables
If a trace buffer is loaded ('Extras' 'Start Trace'), then the values of all variables to be
displayed can be read out ('Extras' 'Read Trace' or 'Extras' 'Auto Read')and will be
displayed accordingly. If no scan frequency has been set, then the X axis will be
inscribed with the continuous number of the traced value. The trace buffer will be
deleted as soon as the trace sampling is stopped ('Extras' 'Stop Trace').
The status indicator of the trace window (first line) indicates whether the trace buffer
is full and when the trace is completed.
If a value for the scan frequency was specified, then the x axis will specify the time of
the traced value. The time is assigned to the "oldest" traced value. In the example, e.g.,
the values for the last 25 seconds are indicated.
The Y axis is inscribed with values in the appropriate data type. The scaling is laid out
in a way that allows the lowest and the highest value to fit in the viewing area. In the
example, Var 0 has taken on the lowest value of 6, and the highest value of 100: hence
the setting of the scale at the left edge.
