How to use TAM System Explorer
Scope
3.3.1 Scope Settings
To modify the scope settings, click the
Scope
tab in the tab panel or click the scope area to activate the
Scope
tab. At the right, the list of registers (called
Plots
) assigned to the scope is shown. On the left, the
tabs with the scope settings are displayed. The scope settings are divided into three groups:
The
General
tab specifies scope properties valid for all plots.
The
Plot
tab specifies the properties of the currently selected plot.
The
Cursor
tab owns the properties of the two cursors and the trigger.
To remove a plot from the scope, select the plot in the plot list and press Delete or click the
Delete the
selected plot(s)
button .
Remark
Remark
Scope settings can only be modified while the scope is not running.
3.3.2 Sampling Time
The default sampling time is one millisecond. The sampling time can be increased or decreased by
changing the
Default Sampling Time
in the
General
tab for all signals or by changing the
Sampling Time
in the
Plot
tab for individual signals (Figure 11 and 12). The following sampling times are supported:
0.01ms, 0.02ms, 0.1ms and multiples of 0.1ms. Unsupported values will be rounded to the next valid
sampling time.
The maximal number of values which can be received from a drive depends on the sampling time and
the data type of the register. Most registers contain 32-bit values, only absolute positions without a
'Float' identifier are 64-bit values. The following table shows the maximum number of plots depending
on the sampling time and the register type:
Sampling Time [ms]
32-bit values
64-bit values
0.01
8

0.02
16

0.1
80

0.1 · n
80 · n
40 · n
When the maximal number of plots is exceeded, an error message will pop up (Figure 6). In this case
the number of plots must be reduced or the sampling time increased.
