6. Click Submit. References to the target data points are added underneath the source data point in
the local tree on the left frame.
7. Test that your Web connections are updating the FPM data points accordingly following these
steps:
a. Click View and then click Data Points. The View – Data Points Web page opens.
b. Close the graph by clicking the ‘X’ in the upper right-hand corner of the application frame.
c. In the tree, click the data points under the FPM functional block that are members of a Web
connection. Click the data points on the SmartServer that are bound to the FPM data points in
the Web connections.
d. In the following example, observe that the nvoHVACMode_1 output data point on the
HVAC device (#2) has the same value as the nviHVACMode_1 input data point on a
different functional block on the HVAC device (#3); the Analog_Temperature data point on
the external Analog Input device (#4) has the same value as the nviTemp_1 input data point
on the HVAC FPM device (#5); and the nvoAC_OnOff_1 output data point in the HVAC
FPM (#8) has the same value as the nviClaValue1 data point on the SmartServer (#9). These
data points are bound with Web connections, which keep these data points synchronized.
e. Enter different values for the input data points in the Web connections and observe that the
FPM application processes the updated values received by its input data point and writes a
value to the output point, The Web connection propagates the updated value in the FPM
output data point to the input point to which it is connected, which may be on the
SmartServer, on another FPM, or on an external device.
In this example, the value in the Analog_Temperature data point on the external Analog
Input device (#4) has dropped to 65
°F. The Web connection propagates this value to the
nviTemp_1 input data point on the HVAC FPM device to which it is connected (#5). The
decreased temperature is calculated by the FPM application, which results in its
nvoAC_OnOff_1 data point (#8) being changed to OFF. The Web connection then
propagates the updated OFF value in the nvoAC_OnOff_1 data point to the nviClaValue1
data point on the SmartServer (#9).
