Hello Múrof, Using WinCC RT Professional, after I have set up a Data logs and worked with the project loaded on a PC station, how can I access the database to see the values of the registered logging tags? I am not able to find any information about this. Thanks in advance

Hi Erm2222_ As far as I know you can do that by using the WinCC OLE DB. Here you can find more information about how to do it: https://support.industry.siemens.com/cs/ww/en/view/109798671/39129326731 Hope you find it useful. |
Best regards, |

Hello erm2222_ If you just want to view the logged values then use a Tablecontrol or a Trend Control in sour WInCC Prof Runtime. If you want to read out the values from an external application then can use the Runtime API: https://support.industry.siemens.com/cs/ww/en/view/109813306/143300782219 But you cannot look just inside the SQL Table because the Taglogging DAta is stored comressed Bye Murof |
