LNS Plug-in Versions

Version 1.01

This was the first released plug-in version for the WattNode Logger.

Updated plug-in to correctly update resource catalog. Installer no longer tries to do this.
Updated some status indications to appear in pop-up window during plug-in initialization (before main form visible).
Validates resource file versions.
Better error handling if the CSV log file isn’t writable (typically because it is open in Excel).
Updated handling of enabling and disabling network variable monitoring.
Only display one digit to the right of the decimal point for VAC measurements.
No longer converts date of 0000-00-00 (null date) to 2000-00-00.
Comma’s between thousands, millions, etc. for power, demand vars, like energy.
“Read Log” button grayed out during download.
When energy reaches 100,000 kWh, stop displaying digit to the right of the decimal if we’re using a floating point energy SNVT, because LNS only provides six digits of precision.
Displays “Offline” or “Read Error” if the WattNode meter is offline or we cannot communicate with it.
Periodically checks the WattNode state and error and updates the display.
