Time management issues

Symptom
Solution
You have forgotten the module's time synchronization source.
Go to
Web Diagnostics
, and under the
Hardware
 tab check the
Time Management
 page. The time source is listed in the
Time Source
 section.
The module is synchronized to a controller time source and the controller time is moving back, causing the module time to move back.
  • Correct the controller time. Download archives to save the archive data with future timestamps.
  • Click
    Safe Mode
     that initially appears when the module is restarted. (Safe Mode indicates that your system is in safe mode.) Do not delete the archive files.
The module is synchronized to an NTP time source, and the module time is incorrect.
  • Check that the NTP server is running properly.
  • If the NTP server is running properly, check the NTP log; this indicates if the NTP time was successfully synchronized during initial configuration or not. If it was, then it must be resynchronized. Navigate to the
    Advanced
     tab,
    Time Management
     screen. Select the
    NTP Server
     option, retype the NTP server address, and click
    Save
    . This will restart the module and may take several minutes to complete. If the module was never successfully synchronized, then you must do so now. For details, see Manage time.
The module starts in safe mode after a restart because the user accidentally typed a past time when configuring the module time.
  • The
    Time Management
     page will display a warning message. Correct the module time configuration on the Time Management page.
  • Restart the module.
