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

Also check the settings in your wincc if this feature is enabled. 2. If you are usingthe COM cable just check it once again for proper functioning. Thanks AGR
