Trend value mismatch on Redundant Servers

12/12/2011 10:23 AM	Rate (0)
R J Posts: 215 Rating: (12)	Hi to all, Currently i am working on "PCS7 V6.1 Sp3". We have established redundant server & client architecture in plant. Time synchronisation is also established between redundant server's, clients & CPU 414-2H. We are capturing trends on both servers but it showing "different values at the same time instance" whenever the surge occurs in the process for particular process parameter. How to resolve this problem? Kindly provide the solution.

Do they have the same PC time? Is the time synchroniszation OK? If the time synchronisation is running without mistakes and the archives are synchronized, the values must be the same. Regards
