TIA Runtime takes long time when starting up with the OS system

[anhtuandrg 0]

I have a project that run WinCC in a PC that has configuration: Core i5, RAM 4GB, HDD 500GB. WinCC connected to S7-1200. I built a runtime file, and set up Autostart in WinCC RT Start. At the beginning, it took about 1-2 minutes to open the runtime file, but now it takes me about 15 minutes to open it. In this project, I used VBscript to write data to database of Microsoft SQL 2008 in particular event.

Can anyone give me some advise?

How much time has passed between the initial, "it took about 1 - 2 minutes", to the current, "it takes me about 15 minutes"? Only a few days? Some weeks? Some months? A year or more?

Hi Pop,

Sorry for late answer. WinCC began to run slowly after 2-3 weeks. I think that problem was caused by the large number of database that I saved in Microsoft SQL. Everyday, there were more than 36 rows of data which were inserted into a table. But I don't know how to accelerate the performance. Do you have an idea?

Thanks
