Hi,

How can logged values be read from an external PC?

For example, if a customer wants to retrieve some logged data and implement it in PowerBI.

Thanks

Hello jthyge1!

Access to the 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 requires you to program everything yourself; let's say it provides you with the drivers to decrypt it, but you have to program everything on your own. If we make a cooking analogy, I would give you the ingredients.

The Industrial Data Bridge is a standalone application separate from engineering software or runtime that provides you with data in certain formats. If we continue with the cooking analogy, I would give you the cooked ingredients. You just need to plate them.

And finally, the Information Server generates the information for you, already in formats. In other words, going back to the cooking analogy, it serves everything to you already plated.

From Industrial Data Bridge, you can find the example: "WinCC/Industrial Data Bridge: 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"

Installation setup, installation, and commissioning for SIMATIC Process Historian and SIMATIC Information Server with WinCC and WinCC Runtime Professionall"


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