Determine Which Processes Are Needed
Creating a Practice Test Procedure 160
An alternate method—
building and testing
functional layers
An alternative method for building test procedures involves separating the test
procedure into functional layers and adding, sequencing, and setting the
parameters for all of the processes within each layer before building the next
layer.
As an exercise, you could build the sample procedure this way.
For instance, rather than adding all the processes required for the test to the
procedure table, at first add only the command processes. This defines the
command layer of the procedure. Next, sequence and set the parameters for the
command processes, and run the procedure to ensure that the command layer is
functional.
Next, add the data acquisition layer to the command layer. To do this, add,
sequence, and set the parameters for the data acquisition process. Then run the
procedure to ensure that both layers are functional. You can check the data stored
in the MPT specimen (created when you run the test) to ensure that you are
getting the type of data you expect.
Finally, add, sequence, and set the parameters of the processes used to control the
cooling fan.
Note The advantage of building procedures in functional layers increases with
the complexity of the procedure. Using this method in reverse is also an
effective method for debugging procedures.
Station configuration
requirements for the
practice test
procedure
The practice test procedure in this section requires a station configuration with
resources that support the test objectives and specific MPT processes used.
If you want to perform the practice test procedure on your workstation as shown
in this manual, you should create a station configuration before continuing on to
the next task.
To do this, use the Station Builder application to create a station configuration
with the following attributes:
• A control channel with force and displacement control modes
• An auxiliary data channel named “Temperature Monitor”
• A digital input channel named “Continuity Monitor”
• A digital output channel named “Fan Switch”
The practice test procedure uses these specific channel resources for setting
process parameters. For information about creating station configuration files,
see the 793 Control Software manual (PN 100-147-130).
