Setting the Meter Time
The real time clock on an E50 meter does not have battery backup. The time resets to the millennium (January 1st, 2000)
whenever the meter is power cycled, but it can automatically synchronize to a network time source if set up properly. Otherwise
the meter time can easily be manually set to a computer's time or to a custom time using the plugin (while the device is
commissioned and online).
Setting up Automatic Syncronization to Network Time Source
1. Locate a network time source with an output network variable of type SNVT_time_stamp.
2. If a NodeObject functional block for the meter has not already been created, drag the "Functional Block" shape from the
LonMaker Basic Shapes stencil onto the drawing. If it already exists, skip to step 5.
3. From the popup dialog, select the meter from the Device section, and in the Functional Block section choose "NodeObject"
from the Name drop-down list.
4. Press Finish to create the functional block.
5. If the functional block does not have the input network variable nviTimeSet showing, drag the "Input Network Variable" shape
onto the NodeObject functional block.
6. In the popup dialog, select "nviTimeSet" and press "OK."
7. Create a binding between the output network variable of the time source to nviTimeSet on the meter by dragging the
"Connector" shape onto the drawing and connect it between the two network variables.
