Open the initially created HMI project.

Select the Data Sources Manager object.

Click Add Object ‣ Data source .

Specify a name for the data source. Example: Data_Source_Alarm and click Add.

⇒ The Initialize data source wizard - Provider settings dialog opens.

In Name or address of device, specify the network name of the active controller whose data should be visualized. Example: Device_A

⇒ The connection from the development system to the controller is established and the available variables are read. The Initialize data source wizard - Search data source variables dialog opens. The variables of the Device_A controller that can be accessed are listed in a table.

For the visualization of data from a remote alarm manager, you have to activate non-explicit variables. The required data is exchanged between the HMI and the remote device via internal communications services.

⇒ The data source is created initially and inserted below the data source manager.

Now create your visualization as usual. Open the editor for the visu­alization and add the Alarm table element.

Select the element.
