# Siemens WinCC

A WinCC data source represents data from WinCC servers. A data source in JUNE5 can be created for each WinCC project. This data source provides access to the data of the WinCC process value archive. Online data, alarm archives, and user archives are not supported. The data to be imported is determined via the WinCC tag logging variables.

The connection to the WinCC archive databases is established via the WinCC OLE DB Provider. The Microsoft Message Queuing services and the WinCC Connectivity Pack are required for this. If the client computer does not have WinCC software installed, a WinCC Connectivity Pack client must be installed. The Microsoft OLE DB Provider is also used to retrieve the list of archived variables from the WinCC runtime data. WinCC archives with archive variables must be engineered. The "ARCHIVE" table must be present in the WinCC runtime databases.

When evaluating data from the WinCC process value archives, only values with a status of good (128) are considered.

WinCC V7.3 or higher and PCS 7/WinCC V7.3 or higher are supported.

A JUNE5 license (Professional or Enterprise) with the option Data Source (Order No. JUNE5-OPTN-DS-WCC) is required.

The firewall must be configured by IT so that the server is accessible in the network via remote access.
{% endhint %}

### WinCC Server User

{% hint style="info" %}

* Only users in the same domain or workgroup as the computer on which a WinCC server is running can access process data of the WinCC server.
