Hi everyone,

I am trying to read tagnames from the archive with the VBA script.

I was hoping that ListTlgTag method can work, but it returns something that I cannot read.
Only thing I can get from it is LBound or UBound. 

I was trying to work with that like with array or list, but it seems it is the wrong way...

Do you have any idea? 

Regards,

Kalafony

Hi Kalafony,

Access to WinCC databases is encrypted and you need one of the paid options to access them: Connectivity Pack, Information Server or Industrial Data Bridge.

The connectivity pack you have to program everything, let's say it gives you the drivers to decrypt it, but you have to program everything. If we make a simile of cooking, I would give you the ingredients.

The Industrial Data Bridge is an application independent of the engineering or runtime software that provides you with data in certain formats. If we continue with the simile of cooking, I would give you the cooked ingredients. You just have to plate them.

And finally, the Information Server generates the information for you, already with formats. That is, going back to the simile of the kitchen, it gives you everything already on a plate.

From the Industrial data Bridge, you can find the example: "WinCC/IndustrialDataBridge: Writing data from SIMATIC WinCC or from SIMATIC controllers in MS Office files":

For the Information server, you can follow the example: "Creation of report templates for the Information Server based on Process Historian data in the WinCC and PCS 7 Environment":

"Plant configuration, installation and commissioning for SIMATIC Process Historian and SIMATIC Information Server with WinCC and WinCC Runtime Professional":

Finally for the Connectivity Pack, you can follow this example: "Exporting Archive Data with the Aid of the SIMATIC WinCC/Connectivity Pack (OLE DB Provider)":
