Timing Group
The sliders can be moved in several different ways.
1. With the mouse pointer over the slider, left click and hold while dragging the slider back or forth to the desire
setting.
2. With the mouse pointer over the slider, left click on the slider and then the arrow keys on the PC keyboard can
be used to move the slider in fine increments. The Page Up and Page Down keys move the slider in course
increments. The Home key will move the slider all the way to the left and the End key will all the way to the
right.
Sample Rate
The Sample Rate slider gives the user control of time spacing for the captured date. To give the user a better idea of
what this number means, the total number of samples and total capture time is displayed on the bottom of the “Timing”
group box.
Trigger Offset
The Trigger Offset slider corresponds to the number of samples that will be included on the graph display and data
capture prior to the actual trigger. If the Trigger offset slider is completely to the left (min samples), the data capture and
graphing will start at the trigger location. If the slider is completely to the right (max samples) the graph will capture data
until the trigger point.
Buffer Upload Size
The buffer upload size slider truncates the drive captured data. If the slider is completely to the right (max) the complete
buffer will be uploaded. If the slider is completely to the left, only 1% of the buffer will be uploaded. This parameter does
not effect the data capture size, it only defines how much of the buffer will be uploaded.
Data Group
Data Channel 1 - 4 Select List Boxes
The Channel 1 through Channel 4 list boxes give the user options for parameter display. If parameters with the same
units are mapped on adjacent channels then the graphical display will show these two parameters overlapped on the
same x/y axis. If it is desirable to have two adjacent Channels with the same units mapped to separate axis on the graph
then the selection (none) should be used on the channel in between these two parameters.
Trigger Radio Buttons
Selecting the radio button will cause the graphical capture to trigger the capture off the selected Channel. The “Trigger
Level” text box on the bottom of the display will change units to the selected channel's parameter units. This trigger level
may be changed at any time but the change must be sent to the drive via the Update to RAM or Download button. If a
manual trigger is desired, set the channel to None and select the corresponding trigger radio button. If no trigger is
selected the capture will begin when the Run button is clicked and end at the end of the Sample Rate.
Module Parameter
A Module parameter text box is only available once the user has selected Module Parameter from the Select list box.
This field is used to define what parameter will be plotted on that channel. The module parameter can be entered two
ways: by just typing any module parameter using the program format for the variable, or click the Popup Variables button
and the variable window will open. Then select the variable and drag it over to the channel module parameter text box.
Trigger Mask List Box
This list box is only available when Drive Inputs, Drive Outputs, Module Inputs or Module Outputs is selected in the
channel select list box and the Trigger radio button is selected for that channel. The Trigger Mask list box will only list
the inputs or outputs for the selected channel parameter.
Trigger Falling Edge Check Box
When the Trigger Falling Edge check box is selected, the trigger is detected when the data transitions below the trigger
level. When the Trigger Falling Edge check box is clear, the trigger is detected when the data transitions above the
trigger level.
Trigger Level
This is the level at which the graph is triggered. The “Trigger Level” text box will change units to the selected channel's
parameter unit. This trigger level may be changed at any time but the change must be sent to the drive via the Update
to RAM or Download button.
