how can i change date and time on 800xa system
we are using 800xa system.we have 5 connectivity server,historian,egg work station,aspect server(DC),operator work stations.all are running under single domain controller.all five connectivty server are connected with external gps clock through NTP..connectivity server 1 and 2 in service and standby prospectively.recently connectivity server 1 hasbeen down the reason was nic card damaged.after that all servers and clients date and time hasbeen changed.the date showing 3 days back and time also running 8 hours differents.i tried to sync time from ntp server its syncing but the time only exist 30 second after that its going back to normal.i dont know which is the source of wrong time and where its coming from..please how can i change all our server time as well as connectivity server time on 800xa system....thank you for you valuable time
I guess its easier to setup a new time synchronization scheme than trying to debug the existing system because you seem to have no clue on how the current setup is handling time.
Recommed you to check the following document:
Section 7:Time Syncronization.
Choose one out of many possible combinations mentioned in the document and implement the same.
I think there is some configuration issues in the time synshronization. Because even your one of the connectivity server goes down secondary should take over the time sync from external time source.
refer the below document for Time sync with external toime master.
3BSE034463-510_E_en_System 800xA_5.1_Network_Configuration and sectioon 7
Can you elaborate how you have configured time sync?
whether you have connected GPS to control network(what kind of connects you are using)?
Share your system configuration to help you better.
In general for better accuracy you have to do the time sync from controller to system(Bottom to top) instead from system to controller level(top to bottom)
To perform the time sync from controller to xA ensure the following:
Am giving example for 800M connect controllers
1.Connect the GPS(SNTP server) to control network & enable the SNTP in the controller settings for any one controller & made clock order as 1 & for rest of the controllers make clock order 0
so that other controllers acts as CNCP slave & main controller acts as SNTP client & CNCP master.
2.Enable the IP forwarding in Conenctivity servers so that these acts as router for non-xA nodes like domain server.
3.Afw time server creation:enable the time service with service group "server running" select the connectivity servers as service providers(as redundant servers)
4.In node admin str for each node select the time sync aspect "uncheck" set time from this node.
5.Disable the windows time service in xA nodes except Domain controller since it not supports afw time service.
6.In domain controller enable windows time service, SNTP Client=1 & make type as NTP, configure SNTP server.
The recommended Tim sync solution is , Your GPS should point to Controller directly and from controller your 800xA Connectvity sever should sync using PPA Time adapters.
When you use PPA time adapater, not recommend to use Windows Time.. Windows time you can use only for Domain controller if they are not Combined with Aspect server.
No issues. then no need to use NTP server for time sync.. Follow the steps
1. Connect your GPS Clock network to Control Network and make sure the AC800M controller IP and GPS Clock IP both are in same series
2. Configure any one of AC800M Controller as SNTP Slave and point to GPS Switch directly
3. the same AC800M Controller configure as CNCP Master.. the respectivity connectivity sever acts as CNCP Salve which will recive the time from AC800M Controller
4. Keep only the respective connectivity servers under Time service in service structure
delete all other nodes if appears under Time service
5. Disbale windows time service on all the nodes..
6. Enable TCP/IP forwarding in all connectvity servers
