Synchronize System Clock E Series

by | Mar 23, 2023 | Trouble Shooting E-CE Series, Trouble Shooting E2-Group

The Red Lion RAM system clock will synchonize with the NTP pool hourly.If power is OFF for a long duration, the clock at boot-up may not have a chance to sync with the NTP server thereby causing tags not to update to GRIDview and participate at the wrong time in AutoDR Events.

This is how to quickly correct the time error.
