Echelon SmartServer 2.2 - Manual (Page 137)

138 Using the SmartServer Web Interface
6. A functional block representing the selected application and all the data points statically defined
for the functional block are added under the i.LON App (Internal) device network object at the
bottom, and the application opens in the application frame to the right. The construction symbol
overlaid onto the application icon in the upper-left hand corner of the Web page indicates that the
application has not been configured yet.
7. Click Submit.
Note: You can click View to open the Alarm Notifier: Summary, Alarm Notifier: History, Data
Logger: View, and the View - Data Points Web pages.
To open an application from an existing functional block instance, follow these steps:
1. Click General. If Driver is selected when you click a functional block, the Setup - LON
Functional Block Driver Web page for the functional block opens instead of the corresponding
SmartServer application.
2. Click the functional block representing the SmartServer application to be opened. The application
opens in the application frame to the right.
See the next section for how to add data points to SmartServer applications.
Using OpenLNS CT to Open SmartServer Applications
You can create an instance of a SmartServer application’s functional block and open the application
using OpenLNS CT. Using this method to open a SmartServer application is comparable to launching
an OpenLNS plug-in. You right-click the functional block shape representing the SmartServer
application to be configured, and then click Configure on the shortcut menu. For more information,
see Opening SmartServer Applications with OpenLNS CT in Chapter 12, Using the SmartServer with
OpenLNS CT.
Adding Data Points to SmartServer Applications
The applications on the SmartServer work with the network variables from L ON W ORKS devices, and
also work with data elements from M-Bus and Modbus devices. For example, an Event Scheduler can
schedule an M-Bus or Modbus register just as easily as it can schedule a L
ON W ORKS network variable.
This flexibility enables the SmartServer to integrate legacy devices from other field busses. The
integration of other field busses with a L
ON W ORKS network is accomplished by the SmartServer’s data
server. The data server is a software component that abstracts any data element of any bus into a data
point. It enables the SmartServer applications to operate on these abstractions without regard of the
device driver.
The following figure illustrates that the SmartServer applications monitor and control the data points
abstracted by the internal SmartServer data server. The data server abstracts the network variables on
