A server (1) with a memory (7) that stores files for configuring an automation system. A remote client (4) accesses the files over communication links (2, 3, 5, 9, 10) via an interface (6, 8) in the server. The interface includes first means (8) for transmitting to one or more remote clients a copy of selected files in the memory. The interface further comprises second means (6) for receiving from remote clients files produced or modified by the remote clients. The first and second means of the interface convert the files between a format in the memory that can be processed by the server and a format for transmission that can be processed by the client.
