12. 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.
Downloading the Data Log (E50F5A only)
Records from an E50F5A's log can be downloaded to a new CSV file or appended to an existing log file. Appending to an existing
file saves time by just adding the records that have been created since the file was last updated. If appending to an existing file,
an unaltered CSV file from a previous download must be used, and the headers must match the points that the meter is currently
logging.
Download to a New Log File
1. Verify the meter is commissioned and online, and the LonMaker Management Mode is OnNet.
2. If the plugin is not open, right-click on it and select "Plugins"-> "Veris E50 Download Log" from the context menu. If it is
already open, click on the "Data Logging" tab.
3. On the left side of the "DOWNLOAD LOG" section, select "Create A New Log File."
4. Press the "Choose Path" button, choose a destination folder, and press "OK."
5. Enter a name for the log file in the "File Name" text box. If a unique file name is desired, check the "Append Date/Time to File
Name" checkbox.
6. To get all the records in the log, select the "Entire Log" option. To get only a specific amount of the newest records, select the
"Fixed Amount of latest entries" option and enter the desired amount in the textbox. The log can hold 5760 records, but both
options stop downloading when they reach unwritten records. For example, when 250 demand subintervals have passed
since the log has been reset, 250 of the 5760 possible log records hold data. The remaining 5510 records are blank. Selecting
"Entire Log" downloads the 250 records with data. Selecting "Fixed Amount of latest entries" and putting 100 in the textbox
downloads 100 entries. Selecting "Fixed Amount of latest entries" and putting 400 in the textbox only downloads 250 records,
since the amount requested is limited to the amount of records in the log with data.
7. Press the "BEGIN DOWNLOAD" button to start downloading the log with the parameters set above.
Append All New Records to an Existing Log File
1. Verify the meter is commissioned and online, and the LonMaker Management Mode is OnNet.
2. If the plugin is not open, right-click on it and select "Plugins"-> "Veris E50 Download Log" from the context menu. If it is
already open, click on the "Data Logging" tab.
3. On the right side of the "DOWNLOAD LOG" section, select "Append All New Records To An Existing Log File".
4. Press the "Choose File" button, select the file to append to, and press "Open".
5. Press the "BEGIN DOWNLOAD" button to start downloading the log with the parameters set above.
Log Download Network Bandwidth Control (E50F5A only)
To control the network bandwidth consumed by the downloading process, use cpLoggedData, configurable on the "PROPAGATION
SETTINGS" tab. The default is a 0.1 second throttle, which amounts to a maximum of 20 packets per second (10 Acknowledged
packets sent, 10 acknowledgments received). The full log download takes approximately 15 minutes at this speed. If the throttle
is changed to 0.2 seconds, 10 packets are sent per second, but the download will take approximately 22 minutes. If 20 packets
per second is not an issue for the network, using the default 0.1 second throttle is recommended. Note: avoid using the "Network
Variable" tab and collapse the "LOG INFO" section of the "DATA LOGGING" tab while downloading the log if controlling bandwidth
usage is a priority).
