Abstract: There is described a method for operating an automation device and/or a programming system. When the automation device is in operation, a communication connection between: a) the automation device and a telecommunication device and/or b) the automation device and the internet and/or intranet can be established. The automation device is controlled and/or regulated by means of a program. The communication connection is used by means of at least one instruction in the program for the data communication during the execution of the program. It is also possible to establish a communication, in particular, within the teleprogram.

Abstract: According to the invention, a server communicates with a client by transmitting to the client pages that the latter requested. The server adds to the pages identification data comprising at least one transmission identifier specific for the transmission of the page in such a manner that said data is transmitted back to the server if and only if the request on the client's end originates from the transmission of the page. The server also stores the identification data transmitted by it. If the transmission identifier transferred back to the server corresponds to a stored transmission identifier, the server, once it receives the additional request, stores the newly transmitted transmission identifier in place of the transferred-back transmission identifier. Otherwise, it stores it in addition to the transferred-back transmission identifier.
