Name
This is the name that will appear in the "Curve Selection List". A default name will be given but the user
should set this to some appropriate name.
Recording Method
If the Free Run Oscilloscope is being used, then this will be set to Free Run. In this case, sample data is
transferred from the controller to the Oscilloscope in real time using PDO messages. If the Single Shot
Oscilloscope is being used, then this will be set to Single Shot. In this case, sample data is recorded in a
TESTSETP array and transferred to the Oscilloscope at the end of the test.
All the following attributes apply only to Single Shot Groups. They affect various aspects of the TESTSETP
array that is configured to record the curve data during the test.
Storage Location
This specifies where the TESTSETP array will be placed. If set to Dynamic Memory, then the TESTSETP array
will be saved in the remaining unused memory in the controller. Note that the amount of unused memory
will vary depending on such things as the size of the loaded program, the number and sizes of any pre-
allocated user arrays, the number of saved programs, etc. If Array is selected, then the TESTSETP array will
be placed in the specified array. This array must be pre-allocated in the controller (e.g. by defining it in an
application program or by using the Array Editor, etc.).
Storage Mode
This specifies what happens when the TESTSETP array becomes full.
If set to Cyclic, then the oldest existing data point will be lost in order to make room for the newest data
point (i.e. the TESTSETP array will contain only the most recent set of points recorded).
If set to Stop when full, then new data points are discarded (i.e. the TESTSETP array will contain only the
first and oldest set of points recorded).
Sample Count
This specifies the number of sets of sample points that can be saved (i.e. it determines the size of the
TESTSETP array).
Note that it refers to the number of sets of points (i.e. one sample point for each curve in the group) and
not to the total number of individual sample points.
If set to Fill available space, then the TESTSETP array will be made as large as possible while still fitting
within either the dynamic memory or the predefined user array. Alternatively, Fixed count can be used if the
user wants a specific number of points only.
Sample Interval
This specifies the time interval, in milliseconds, between each saved set of sample points.
