For the WattNode® LonWorks® Plus model, what features does the Plus refer to?
CCS originally LonWorks models were WNA series WattNode meters that only reported power, energy, and demand. The Plus models were introduced with the WNB series and continued with the current WNC series of WattNode LonWorks meters. The Plus models provide many more measurements, such as individual phase readings, voltage, current, power factor, and reactive power. At this point, we no longer sell the basic models, so the Plus is the standard version for LonWorks.
What is the difference between the Logger and Plus models?
The WattNode Logger model contains the same network variables as the Plus model. Additionaly, the WattNode Logger contains non-volatile data storage and a real-time clock. It stores all measurements to flash memory at a configurable interval from one minute to 12 hours. The log stores 24186 records; at the default 15 minute log interval, this provides more than eight months of storage. A highy accurate clock with battery backup is used to maintain accurate date and time through power failures.
The WattNode Plug-in for LNS is required to download the logged data and convert it to a comma separated CSV format, which can be used with Excel® and other programs.
