How to Define a Timed Acquisition Process
1. Drag the icon from the Process Palette to your procedure table.
2. Click the process icon in the procedure table or in the navigation pane.
3. In the parameters window, click the Acquisition tab.
4. Set the timed data acquisition interval and units using Time Between Points
or type a Sample Rate frequency.
Note When you enter a time increment, the MPT application may change your
entry slightly to reflect your controller’s clock rate.
Note MPT may change the entered sample rate frequency slightly to reflect
the resolution of your controller’s system clock rate. For instance, if you
type in “1000 Hz” and press the enter key, MPT may change the number
to 1024 Hz.
5. If you want to:
• Cause the process to acquire samples continuously until it is
interrupted, select Continuous Sampling (default selection).
• Specify the number of samples to be acquired, select the Total
Samples, then type the number of samples desired.
• Specify the length of time the process will attempt to acquire data,
select Sampling Duration, then type the time over which you wish to
acquire data.
6. Click the Signals tab.
7. Move all the signals you want to monitor to the Included list. Move all the
others to the Available list.
Note The order of the signals in the Included list determines the order of the
columns of data in your data file.
8. Click the Destination tab.
9. Type the Buffer Size and type a description of the data file in the Data
Header box.
10. In the Destination list, click the destination for the acquired data. (If you
click User-specified data file, type a file name in the User Data File box.)
