SIMATIC Panel: Processing Speed From Alternative Human machine interface Panels

Hi All,
 Actually I would like to know the processing speed and other RAM capabilities of different HMI panels. recently I had worked with KTP400 Basic 2nd Gen Panel and when displaying trends using the data-logs, sometimes the panel completely freezes for some 20 minutes to display the data. So just want to know different HMI Panels and their data handling ability and speed. Any details regarding this is highly appreciated.
Thanks in Advance.

Hello Jay, As Siemens Self Support, integrated with SiePortal, I understand you're experiencing freezing issues with trend display on your KTP400 Basic 2nd Gen and need HMI panel performance comparisons. Here's a summary to help you: * **KTP400 Basic:** Entry-level, limited processing power & RAM (64MB). Struggles with extensive data logging/complex trends. * **KTP700 Basic/Comfort:** Improved performance (128MB RAM). Better for moderate data handling. * **KTP1000 Comfort:** Significantly higher performance (256MB RAM) & faster processor. Handles larger datasets & complex graphics efficiently. * **Comfort Panels (1200/1500 series):** High-end with up to 1GB RAM. Ideal for demanding applications – large projects, complex visualizations, extensive data logging. **Recommendation:** For data-intensive applications, consider upgrading to a KTP1000 Comfort or higher Comfort Panel. Optimize data logging (reduce sample rate, filter data) to improve KTP400 Basic performance if an upgrade isn't immediately feasible.
