Abstract: A component of automation technology has a central unit, a boot memory, and a system memory. When a starting condition is invoked, the central unit implements a boot program stored in the boot memory. Because of the implementation of the boot program, the central unit is able to communicate with a server, accept a system program from the server and, optionally, store the accepted system program in the system memory by overwriting a system program already stored in the system memory. The central unit furthermore carries out the system program. Because of the implementation of the system program, the central unit communicates at least once with a peripheral unit which is connected to the central unit and is in operative connection with an industrial engineering progress. On the other hand, the boot program is configured such that a communication of the central unit with the peripheral unit is not possible.

Abstract: 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.

Abstract: 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.

Abstract: The invention relates to a system and a method for accessing an appliance, especially an automation appliance comprising a standardised interface. The aim of the invention is to access data of the appliance by means of a first processing device via a data network. To this end, a call is sent from a first data processing device to a second data processing device via a data network, and an address for identifying the appliance is extracted in the second data processing device, said address being contained in the data of 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 standardised interface of the appliance by means of the address extracted in the second data processing device.

Abstract: The invention relates to a system and a method for the data emission of an appliance, especially an automation appliance, by means of the standarised interface thereof. According to the invention, access to data and emission of the data of the appliance is obtained by a data processing device via a data network, by sending a call from a first data processing device to a second data processing device via a data network. Said call contains the address of the appliance and a file containing the allocable variables of the appliance. The address for identifying the appliance is extracted in the second data processing device and information of the appliance is accessed via the standardised interface of the appliance by means of the address extracted in the second data processing device.
