Hi, There is a good FAQ on that topic: How do you access an SQL database in WinCC flexible via a script? This will give you overall idea on how to access SQL with the script. On the other hand if you want to access logged tags then you need to open SQL server with SQL Management Studio and then see the structure of Flexible database. Once you know structure you can build your own queries to access tags in the database. |
Best regards, |

Hi, Well you need to do all steps as in FAQ. Here in your example I see that maybe you mistyped datasource name or something else. I do not see what you are doing and I don't see your project to determine cause of an error. I can assure you that example above works just fine. Please take a look at another FAQ. Maybe you will find something valuable there: How do you log tags in an SQL database and read them out again with WinCC flexible? |
Best regards, |
