MTS MultiPurpose TestWare®
Creating Profiles
Model 793.11 Profile Editor 510
Next, select the Multipurpose TestWare application, then open the MPT
Procedure Editor (it will appear with a blank procedure table displayed). You can
create a new test procedure or open an existing procedure. The procedure must
contain the Profile Command process. Once the procedure is loaded, you then
select the profile file you created. This is done by double clicking the Profile
Command processes icon on the procedure table. The Profile Command
Parameters window will appear.
On the Command tab, click the Profile Path/File button and select the desired
profile file. An error message may appear to tell you the channel has not been
mapped. Click OK, and then click the Mapping tab.
On the Profile Channel pull down menu, select the desired channel and
complete the remaining fields. Complete the remaining tabs on the Profile
Command Parameters window. Finally, using the run button on the station
controls panel, run the profile.
About Using Normalized Dimensions
If you create a profile using a normalized dimension, such as ratio, percentage,
unitless, or volts, you can select any of the control modes available to the station
configuration when selecting the control mode for the profile channel.
When you do this, you define the full-scale value of the normalized dimension by
selecting one of the control modes and its associated engineering dimension
available in the Control Mode list on the Mapping tab, along with a unit type
and a Level Multiplier value. MPT converts all end level values in the profile to
command levels accordingly.
Example
Suppose you create a station configuration that uses the force dimension for a
force control mode, and the length dimension for a displacement control mode. In
addition, suppose you create a profile in which you select the volts dimension to
define end levels.
Next, you start MPT against the station configuration, and with the Profile
process, on the Command tab, you select the profile you have created. On the
Mapping tab, you select a Profile Channel. In this scenario, both displacement
and force will be available in the Control Mode list.
Suppose you select displacement, and type a value of 5 cm in the Level
Multiplier box. This will cause all of the end level values in the profile to be
converted to displacement values. For volts, the full-scale value equals 10 volts,
which MPT will play out as 5 cm. So in this case, if the first end level values in
the profile are 2 volts and 9 volts, they will be played out as 1 cm and 4.5 cm.
