Complete the following steps to import a VI from LabVIEW with the Run 
LabVIEW VI Step.

1.

Select File»Open Project, navigate to the 

SignalExpress\

Examples\Tutorial

 directory, and double-click 

User

 

Step.seproj

.

This project uses the Create Signal step to generate a signal.

2.

Click the Add Step button and select Run LabVIEW VI»Run 
LabVIEW 8.2 VI. 

The VI you run in this exercise was saved in LabVIEW 8.2. You must 
use the version of the Run LabVIEW VI step that matches the version 
of LabVIEW you saved your VI in.

3.

Click the browse button on the Step Setup dialog box and select 

Limiter-LV82.vi

 in the 

LabVIEW SignalExpress\Examples\

Tutorial

 directory. The Limiter-LV82 VI accepts a time-domain 

waveform as an input, clips the signal above and below values that you 
specify in the Step Setup dialog box, and returns the clipped 
waveform as an output signal.

When you import a LabVIEW VI, LabVIEW SignalExpress maps the 
inputs of the VI as parameters and the outputs of the VI as output 
signals in LabVIEW SignalExpress.

You can define whether the inputs for VIs become input signals or 
parameters. An input signal appears in the Project View as an input to 
a step, which means you can pass signals as inputs to a VI. A parameter 
is a value you can configure on the Step Setup dialog box of a step. 
You also can sweep parameters dynamically using the Sweep step. In 
this project, the VI has an input signal, Time waveform in, and scalar 
parameters, Upper limit and Lower limit.

Verify that the Step Setup dialog box appears as shown in Figure 7-1.
