Restore configuration files
The Restore function sends the backup file from its location on a host to the remote controller to restore operation, if the
configuration is lost or corrupted. This procedure assumes that a configuration file backup already exists (If not, backup the file
before attempting to restore the file, see section 4.2.1.1, Save configuration files).
To restore configuration and calibration data files:
Start PCCU. The main PCCU screen displays.
On the main PCCU screen, on the top menu, select Operate > File Utilities> Save and Restore Utility or click the Save
and Restore Utility icon on the toolbar. The Save and Restore screen displays.
Click Restore Station Files at the bottom of the screen. The Restore Station Files dialog box displays.
Define or verify the file path where the backup file is located. If there are several backup files, make sure to select the
desired one.
Click OK.
Wait for the restore to complete. Progress status messages display at the bottom of the screen.
Perform a cold-start (cold boot) to load the restored data. Select the cold start method in section 5.3.8, Reset procedures.

Clock change not crossing an hour boundary
When the next log period entry is made, the clock is not altered.
Example: If present time is 4:15 p.m. and the clock is changed to 4:05 p.m. of the same day, the daily flow record is the same.
Entry reflects averages accumulated over a 70 minute time period (15 minutes plus 55 minutes).
Forward clock change crossing an hourly boundary
This forces a log period entry for part of an hour that has accumulated since the last hourly entry. XRC

Example: If present time is 4:55 p.m. and clock is changed to 5:05 p.m. of the same day, the entry reflects only a 55 minute
average accumulation. Then a new flow record is written, and this period is also based on a 55 minute accumulation.
Backward clock change crossing an hourly boundary
Hourly entry is made for the part of the hour that has accumulated since making the last hourly entry. This is the same as for a

Example: If present time is 5:05 p.m. and clock is changed to 4:55 p.m. of the same day, the log period record entry reflects
only a 5 minute average accumulation. Then a new flow record is written, and this log period is based on a 60-minute
accumulation.
