Power Monitoring via SNMP (or Modbus TCP)

Viewing data

Once you have selected which variables are to be mapped and either clicked Auto Allocate or manually entered register numbers, the X2 will begin polling the WattNode. After a minute or two, data will be showing up in the mapped registers. You can also view the data by device if you click on the LON Data tab as illustrated above.

After you save your configuration in the BootConfig.xml file, and reload the file or restart the system, only the mapped registers will appear. The screen shot below illustrates the reloaded LON Variables page. Note that unmapped variables do not appear. (You can recover them by repeating the Get XIF from Device process).

(Note: Power data shown in the examples on these pages is nil because we had no load on the CT's while capturing these screen shots.)

The LON Data page will appear more like the example below when the configuration has been reloaded without unmapped variables represented.
The status indicated on the LON Data page will be "Ok" if the Babel Buster X2 is successfully polling the WattNode (or other LonWorks device). Upon initial startup, status will be also shown as "Ok" if polling has not yet started. But once polling begins, if the LonWorks device fails to respond, the indication "NV fail" will appear. Most often, if it appears for one variable in a device, it will appear for all variables in the device. This indicates there is a device level problem. If the "NV fail" ever appears on only one variable, while other variables in the same device are responding Ok, there is something wrong with the mapping of that variable.

Once the error indication has been observed and you believe the problem has been resolved, go to the LON Devices page and click the Reset Errors button. This will temporarily set all status indications to "Ok", and any issues that remain unresolved will later change the indication back to "NV fail".

The System Data page will all you to scroll through all data registers which may be mapped to multiple devices. The same LON data is illustrated on the System Data page below.
