122 Deploying Freely Programmable Modules on a SmartServer

Testing FPM Applications

After you add an FPM application on the SmartServer, you can test it using the View – Data Points

Web page. To do this, you open the View – Data Points Web page, add the input and output data

points in the FPM device that you can use to observe the FPM application processing data point

updates, update one or more of the input data points, and observe that the output data points are

updated accordingly.

To test an FPM on your SmartServer, follow these steps:

1. Click View and then click Data Points. The View – Data Points Web page opens.

2. Close the graph by clicking the ‘X’ in the upper right-hand corner of the application frame.

3. Under the FPM functional block, click the input data points that affect the values stored in the

output data points in the same FPM functional block and then add the output data points. The data

points appear in the View – Data Points Web page.

4. Enter values for the input data points that will cause the FPM application to update the value

stored in the output data point.

5. Observe that output data points are updated accordingly based on the algorithm you wrote in the

FPM application. In this example, the nvoChiller_OnOff output data point (SNVT_switch) turns

on when the nviTemp input data point is greater than the sum of the nviSetPoint and the

nviHysteresis input data points (all SNVT_temp_p types).

Connecting FPM Data Points

After you verify that your FPM is functioning properly, you can use LONWORKS or Web connections

to connect the data points declared in your FPM to the data points on the internal SmartServer device,

the data points in another FPM application, and the data points of the external devices connected to the

SmartServer.
