AC 800M OPC Server "Failed to connect to the controller. Duplicate application name"
Can somebody help me,what is wrong?
I think the application connected to N1, may perhaps have been downloaded into another controllers i.e N2,3,4 or 5 , and the application is still perhaps present in one of these controllers.
Or have you downloaded the application connected to N1 to a soft controller and is the soft controller connected to the OPC server?

You can add and connect a controller that the OPC Data Access Server should provide data from in the following way:
In the Controller Identity entry field, entering, or drag and drop, the IP address for an available controller.
- Connect the controller by clicking the Connect button.
If you connect to a controller containing a distributed application, an application that exists in more than one controller, all variables in the application are accessible even if they are owned by another controller. To access the hardware configuration of the other controller you must explicitly connect to that controller.
Each of the connected controllers has an icon indicating the current status of the connection to the controller. You will get more information about the status, by double clicking on the controller identity.
The OPC Server needs access to some files (called domain files), describing the content of a controller, in order to connect to that specific control system. These files are created by the Control Builder and fetched automatically by the OPC Server when needed
You are recommended to have the Control Builder, that downloaded the project, running when starting the OPC Server.
