800xa system time shifts automatically forward !
Our ABB DCS consists of 2 AS , 2 DS , 2 CS , 1ES and 6 clients. there is 4 nodes ,each node with 2 redundant pm864 controllers.
on 6 or 7/4/2017 clients reported that their system time shifted forward automaticaly and they couldn't see any event and trend. So we resynched the time using control builder M time set function again. as there was a time shift to a future month ,we deleted the wrong events with wrong dates so the event problem has been solved.
Now we have a problem with real time trends. Although all trend data is available but we can't see parameter changes in real time. by closing and opening the trend window we can see the previous records correctly but not the real time data.
We tried resynching using CBM set time tool again and restarting Connectivity servers but the problem didn't solved.
I appreciate any help here.
