TP170 micro v. TP177micro

I have a WinCC Flexible project that has been running on a TP170 micro without any performance issues. I recently converted the project to run on the TP177 micro. The transition time with changing from one screen to another is unacceptably slow, sometimes 2 - 5 seconds. The communications baud rate is set to 187.5. There are about 170 tags. All set for "cyclic on use" at 1s aquisition cycle time. Is there a reason for this performancedegradation? I would have expected better performance from the latest product, but that's not the case here.

Hi,

Are you using the latest version of WinCC flexible?

• Service Pack 1 for WinCC flexible 2005
• Hotfix 7 for WinCC flexible 2005 SP1
• Service Pack 1 for WinCC flexible 2005 Micro

Also improvements are made if you use different time settings for the aquisition cycle aquisition cycle of some tags.

Looking through the specs I must agree with you I can't see much of an improvement.
