Hi funfrok, In order for the Historian Data Service to connect to the Historian database, you need to set the database connection properties using the Historian Configuration Manager. The Historian Data Manager is only used to create and manage the Historian database. To make the configuration changes, right-click on "Historian" in the Historian Configuration Manager and select "Properties". In this dialog you can set the database configuration properties to the Historian database you created using the Data Manager. Once you have this set, (re)start the Data Service. You will no longer get the event log messages. For further help, see contacts here: Schneider Electric Müşteri Destek Merkezi.
