Resolution
- For I/A Series G3 version 3.8 and newer, patched weather.jar modules resolve this issue. The weather module patches are available for download from the Schneider Electric Exchange as:
weather 3.8.311.1 - G3 Firmware
weather 3.8.213.3 - G3 Firmware
weather 3.8.112.1 - G3 Firmware
weather 3.8.41.3 - G3 Firmware
To resolve the issue in Niagara 4.2 and/or versions of G3 not covered by the patches,
- Clear the hidden flag on the conditionsServer slot of the weather provider and change the value to w1.weather.gov.
- After making this change, the current conditions will update. The conditionsServer slot for each weather report will need to be modified if more than one is being used.
The following is a screenshot of the provider slot sheet. The Conditions Server slot is highlighted. Select Config Flags.
Config Flags dialog. Uncheck the Hidden flag and save.
View the Property Sheet for the provider and modify the Conditions Server to be w1.weather.gov
