It should be noted that the trace might not be plotted completely to the right
hand side of the display, depending upon the time base scale and number of sam-
ples per grid division.
Oscilloscope Table Values
The controller records the required parameter data values in the controller as
table data prior to uploading these values to the scope. By default, the lowest
oscilloscope table value used is zero. However, if this conflicts with programs
running on the controller which might also require this section of the table, then
the lower table value can be reset.
The lower table value is adjusted by setting focus to this text box and typing in
the new value. The upper oscilloscope table value is subsequently automatically
updated (this value cannot be changed by the user), based on the number of
channels in use and the number of samples per grid division. If an attempt is
made to enter a lower table value which causes the upper table value to exceed
the maximum permitted value on the controller, then the original value is used
by the oscilloscope.
Table Data Graph
It is possible to plot controller table values directly, in which case the table limit
text boxes enable the user to enter up to four sets of first/last table indices.
Parameter Checks
If analog inputs are being recorded, then the fastest oscilloscope resolution (sam-
ple rate) is the number of analog channels in msec ( ie 2 analog inputs infers the
fastest sample rate is 2msec). The resolution is calculated by dividing the time
base scale value by the number of samples per grid division.
It is not possible to enter table channel vales in excess of the controllers maxi-
mum TABLE size, nor to enter a lower oscilloscope table value. Increasing the
samples per grid division to a value which causes the upper oscilloscope table
value to exceed the controller maximum table value is also not permitted.
If the number of samples per grid division is increased, and subsequently the time
base scale is set to a faster value which causes an unobtainable resolution, the
oscilloscope automatically resets the number of samples per grid division.
