452 Using Analog Functional Blocks
7. Click Submit.
To open the Analog Functional Block application from an existing Analog Functional Block, follow
these steps:
1. Click General if the SmartServer is not already operating in General mode. If the SmartServer is
in Driver mode when you click the functional block, the Setup - LON Functional Block Driver
Web page opens instead of the Analog Functional Block application.
2. Click the Analog Functional Block representing the Analog Functional Block to be opened. The
Analog Functional Block: Configure Web page opens in the application frame to the right.
Selecting Input Points
You can select any scalar data point (data point with a single field) or the field of structured data point
as an input point. If you are performing a mathematical operation select two or more input points; if
you are performing a logical operation select one or more input points and a compare point.
1. Click one of the Input Points icons ( ). The Analog Functional Block: Data
Points Web page opens.
2. Select the data points on which the Analog Functional Block is to operate from the SmartServer
tree. References to the selected input points ( ) are added to the bottom of the Analog
Functional Block tree, and references to the Analog Functional Block are added directly below the
selected input points (
).
To select a data point of an external device that is being managed with OpenLNS CT, OpenLNS
tree, or another OpenLNS application, you must first copy the data point from the OpenLNS tree
to the SmartServer tree (see Adding Data Points to SmartServer Applications in Chapter 4 for
more information).
3. View the following properties of the selected data points:
Data Point Displays the name of the data point being recorded using the following
format: <network>/<channel>/<device>/<functional block>/<data point>.
This is also the location of the data point in the SmartServer tree.
Format Displays the SNVT, UNVT, or built-in data type used by the data point, and
it specifies the format (for example, SI metric or US customary) used if the
type has multiple formats such as SNVT_temp_f. This field is read-only.
4. Select the Show Advanced check box to view the following properties and configure the rate at
which the data points are updated.
