AC800M controller in 800xa 6.0 system TIME sync with GPS not happening.
AC800m controllers is giving a time sync error & clock sync status also shows nothing.
GPS IP Address. 172.16.4.120
Subnet Mask: 255.255.252.0
AC800M controller: 172.16.4.151
1. Domain controller is combined with AS (redundant)
2. CS (redundant)
3. History servers (redundant)
4. AC800M controller PM866 (redundant)
Removed all time adapters in Service structure, only for CS1 & CS2 created, enabled service group & selected server running.
Windows time disabled in all servers & client from Windows Services.
Controller settings made as per manual, controller is acting as SNTP client & CNCP master.
Checked that controller is able to reach GPS, and using some third party NTP client tools (simulators) it’s verified that GPS is working fine & it’s reaching ABB network.
It looks like the controller is not able to read time from GPS. And GPS is working fine when NTP client is created in windows machine (by adjusting registry entries).
Referred manual 3BSE034463-600_C_en_System_800xA_6.0_Network_Configuration section “external time source.”
Enable Time adapter in CS1 in registry settings.(If not enabled already)
Resart CS1, check time of CS1 server and controller.
Repeat same activity for CS2.
Path to enable "time adapter" in registry settings,
Under ABB\your system version\ you have to search for some time adapter key, i am not able to recall exact path.
Kindly check the following things in CBM
Tools--> Maintenance-->Clock Sycn-->Status
In there all the controllers must be in CNCP except Clock master controller and Redundant controller. Clock master order will be one & Redundant will be 2 and the remaining controllers will be zero. Check the time Quality also.
