 Hi ALP00,

Thanks for your reply.

I have already tried the instructions but still issue is same. This issue only show when the actual date is changed to 26 January. Before that there is no issue. If I change my Laptop current Date to previous date and save as the project in back date then there is no issue.

From 26 January to till the day the PLC timestamp comparing time changed to 1984 while the RTC of PLC is working fine.

Best Regards.

Hi Everyone,

Finally Siemens Support provided the solution for above mentioned problem.

To resolve that issue you must have MicroWin SMART V2.8, if you have older version first update to V2.8 and then install the patch file [...].

If you are getting Microsoft Defender SmartScreen error Just click on More info and then click on Run anyway it will install.

Downloaded and Installed V2.8 but still timestamp mismatch problem persists.

Can you share the link of the patch file ?

Temporary solution of changing PC time to 2024 is working to get the PLC online.

Still waiting for a permanent solution

Hello Manik_Walia,

I am also facing the same issue.

Due to timestamp mismatch, we are not able to open PID tune cotrol panel.

Will you please share the patch or download link for the same. 

Thanks, and regards,
