Configure the Time Server
To configure the Time Server, select Administrative Settings
> Server
Management Server
> Time Settings. Doing so helps makes sure that
files you save to the web server module have accurate date and time
stamps. You can also enable the local controller to get its time and
date from the web server module.
Select This Field If You Want To
SNTP Time Server Use the time from the Network Time Protocol (NTP).
Specify the IP address or host name of an SNTP server on the network. The web server
uses port 123 for this service. The IP address you enter persists over power cycles.
Query Controller Clock Use the time from the local Logix controller (Wall Clock Time).
Specify the slot number of the controller. The web server module queries the Wall Clock
Time of the controller for both time and date. At subsequent power ups, the web server
module queries the controller.
Manual Time Entry Manually set the time and date.
Manual settings do not persist over power cycles.
Local Time Offsets Select the appropriate time zone.
This selection is only available when you select SNTP time server as your “Get Time
Method.”
Update Time at Constant Interval Select how often the web server module updates its date and time.
Set Controller Date/Time Use the date and time in the web server module to set the date and time in the local
controller.
You must also specify the slot number of the local controller.
Important: This feature provides accurate time synchronization to within one second.
