A method for accessing an appliance, especially an automation appliance with a standardized interface, by means of a first processing device via a data network. A call is sent from the first data processing device to the second data processing device via the data network, and an address for identifying the appliance is extracted in the second data processing device from the call of the first data processing device to the second data processing device and used to identify the appliance. Information pertaining to the appliance can be accessed via the standardized interface of the appliance by means of the address extracted in the second data processing device.

System and method for accessing a process control automation device from a network client

System method and computer-readable media are provided for accessing data in a device using a standardized interface Access to data may be obtained by a data processing device by sending a call from a first data processing device to a second data processing device via a data network. The address for identifying the call sender is extracted in the second data processing device and call information may be accessed via the standardized interface through the address extracted in the second data processing device. The second data processing device receives a file containing variables to be requested, replaces the parameters in the file with the corresponding variables of the appliance, and transmits the file with the replaced parameters to the first data processing device.
