Trend view and time synchronization problem

Thorfano Posts: 20 Rating: (0)	Hello, I am using an S7-200 (CPU 224)(STEP7Microwin (V4.0)) and a TP 177B 4" system (WinCC flexible -V.SP1 2008). I used a trend view object on my WinCC project in order to monitor a temperature value. In the trend view I enabled the "display value table" feature. I noticed that there is a time delay in temperature value updating on the table. Does this has to do with Time and Date Synchronization between CPU and HMI? I try to configure a Time and Date area pointer on WinCC flexible (V.SP1 2008) and on STEP7Microwin (V4.0) however the problem didn't solved. What I find strange is that the address proposed by the WinCCflexible was VW0 while the READ_RTC instruction doesn't accept this address. As you realize I am confused and I would appreciate any possible help. Thank you in advance
