136 Using the SmartServer Web Interface

Type Translator. The SmartServer can translate data from one data type to another. This is useful
for integrating devices with incompatible data types, including devices on different busses
(L
ON W ORKS , Modbus, and M-Bus). For example, you can use type translation to translate a
SNVT_temp_f data point to a SNVT_temp data point, convert the SNVT_scene.function and
SNVT_scene.scene_number fields of a scene controller to the SNVT_switch.value and
SNVT_switch.state fields of a switch, and connect an M-Bus data point to a L
ON W ORKS data
point. This application is described in Chapter 11, Using Type Translators.
You can open the built-in applications on the SmartServer with the SmartServer Web pages, or you
can open them with OpenLNS CT if you are using OpenLNS network management services (you
cannot use another network management tool such as OpenLNS CT to access a network when the
SmartServer is managing the network in standalone mode).
Using the SmartServer Web Interface to Open SmartServer Applications
In the e3 release, the built-in applications on the i.LON 100 server were all accessible from the
Configure menu, which has since been removed. The built-in applications on the SmartServer are
represented by functional block icons that are listed directly under the i.LON App (Internal) device in
the tree.
To open an application, click General and then click the functional block icon corresponding to the
application to be opened. For the Alarm Generator, Alarm Notifier, Analog Functional Block, Data
Logger, Pulse Meter, Scheduler, and Type Translator applications, you must first create an instance of
their functional blocks. After you create the functional block instance, the functional block appears
below the i.LON App (Internal) device in the tree, and you can then click the functional block to
open the corresponding application.
To create an instance of an application’s functional block and open the application using the
SmartServer Web pages, you do the following:
1. Click General at the top of the navigation pane in the left frame of the SmartServer Web interface.
If Driver is selected, the Setup - LON Functional Block Driver Web page for the functional
block will open when you are done creating the functional block instead of the corresponding
SmartServer application.
2. Expand the Net network item and then expand the LON channel to show the i.LON App
(Internal) device.
3. Right-click the i.LON App (Internal) device and then select Add Functional Block in the
shortcut menu.
4. The Add Functional Block dialog opens.
