7. Make the necessary changes to the propagation settings and press "APPLY SETTINGS." If the device is online (or soft offline),
commissioned, and the LonMaker mode is OnNet, the configuration property settings are applied to both the network
database and the device. If, however, the above conditions are not met, the configuration property settings are written to the
database only. A dialog box appears when the write is finished, stating where the values were written to. If values were not
written to the device (database only), the device must be resynchronized to the database at a later time. See the "Configuration
Property Resynchronization" section below.
Saving/Loading Configuration Templates
Values on the "Meter Setup" and "Propagation Settings" tabs can be saved separately to template (.xml) files for easy recovery at
a later time or for use with another E50 device. When either of these tabs is selected, a "Template" menu appears highlighted in
yellow on the menu bar.
Save to Template (.xml) File
1. Select "Template"->"Save To Template". If all the values are filled in and are acceptable values for an E50 (range checking is
done here), a "Save As" file window appears.
2. Navigate to the desired folder and create a name in the "File Name" field (or select an existing .xml file).
3. Press the "Save" button.
Load From Template (.xml) File
1. Select "Template"->"Load From Template".
2. Navigate to the folder where the .xml file exists and select the file.
3. Press the "Open" button.
Formatting Power Correctly
LonMark Resource Files before version 13.04 set the default format in the U.S. for network variables of the type SNVT_power_f as
units of Btu/hr. This formatting results in power values being reported about 3.4 times higher than they actually are in Watts. The
plugin always displays correct values in Watts, however, since it uses raw values, not formatted values.
There are a few ways to resolve this formatting issue, described below. Upgrading the LonMark Resource Files is the least tedious
method, but may require checking the rest of the network to verify that no issues have been introduced by the other changes
LonMark has made to the resource files.
Update the LonMark Resource Files
1. Uninstall the current LonMark Resource Files by opening the "Add or Remove Programs" dialog in Windows, selecting the
"LonMark Resource Files 13.xx" and pressing "Remove."
2. In a web browser, navigate to www.LonMark.org, "Technical Resources" (from the menu bar at top) ->"Resource Files"->"Start
SNVT/SCPT Download..."
3. Follow the prompts to complete the resource file installation.
4. Power values are now formatted in Watts.
Manually Update the Power Network Variables
1. In LonMaker, right click on the E50 device and select "Plugins"-> "Echelon AppDevice Browse".
2. Right click on the row for a power network variable and select "Change Format" from the context menu (can alternatively press
Ctrl+A when the line is selected).
3. From the "Select Network Variable Format" dialog, select SNVT_power_f#SI (not #US) and press OK.
4. Repeat steps 2 and 3 for each power network variable.
5. If any of the power network variables are bound (as opposed to polled), repeat steps 2 and 3 for the input network variables
of other devices the meter is bound to. The format of the input network variable on the other end determines the format that
device receives, not the formatting of the E50 meter's output network variable.
