DeltaV uses the Network Time Protocol (NTP) to synchronize system time for all workstations and controllers on the DeltaV Control Network. DeltaV systems that require precise system time derive master time from a Global Positioning System (GPS) network time server configured to a specific IP address on the DeltaV Control Network.
If a GPS network time server is not in use, you can synchronize system time by using the DeltaV System Time dialog. Time and date settings specified in the DeltaV System Time dialog are applied to the Master Time Server node, which broadcasts them to all workstations and controllers on the DeltaV Control Network.
Click the Apply button to synchronize all workstations and controllers on the DeltaV Control Network. Click the Close button to exit the DeltaV System Time dialog without making any time and date changes.
CAUTION!Do not attempt to change system time by using the Windows Date and Time utility, accessed from the Control Panel or the Taskbar clock. The Windows Date and Time utility does not synchronize system time on all workstations and controllers on the DeltaV Control Network. Use the Windows Date and Time utility only to specify the local time zone and to enable the Automatically adjust clock for Daylight Saving Time option.
