5. The Configure – Web Binder Web page opens and the hostnames of the local SmartServer and
any remote SmartServers added to the LAN, which are collectively referred to as Webbinder
Destinations, appear in the application frame to the right.
6. From the Webbinder Destinations tree on the right frame, expand the i.LON Webbinder
Destination icon, expand the Net network, expand the LON channel, and then expand the Math
Device (Internal) device, and expand the Math Function functional block to show its “in1”,
“in2”, and “out1” data points. Click the “Net/LON/Math Device (Internal)/Math Function/in1”
data point to specify it as the target data point. A reference to the target “in1” data point is added
underneath the “count1” source data point in the tree in the left frame.
7. Click Submit.
8. Following steps 4–7, create a Web connection between the “VirtFB/count2” data point in the tree
in the left frame (the source data point) and the “Math Function /in2” data point in the Webbinder
Destinations tree in the right frame (the target data point).
9. Following steps 4–7, create a Web connection between the “Math Function/out1” data point in the
tree in the left frame (the source data point) and the “VirtFB/total count” data point in the
Webbinder Destinations tree in the right frame (the target data point).
10. Click View and then click Data Points. The View – Data Points Web page opens.
11. Close the graph by clicking the ‘X’ in the upper right-hand corner of the application frame.
12. Under the Net/LON/ Math Device (Internal)/VirtFB functional block, click the count1, count2,
and total count data points to add them to the Web page.
If the in1, in2, and out1 data points under the Net/LON/ Math Controller (Internal)/Math Function
functional block no longer appear in the Web page, click each of these data points to add them
back to the Web page.
13. Observe that the Math Function/out1 data point has the same value as the VirtFB/total count
data point. The Web connection keeps these two data points synchronized.
