System and method for data output of a device, in particular an automation device via a standardized interface with variable replacement via an echo server

摘要

The invention relates to a system and a method for the data emission of an appliance, especially an automation appliance, by means of the standardised interface thereof. According to the invention, access to data and emission of the data of the appliance (2) is obtained by a data processing device (3) via a data network, by sending a call (4) from a first data processing device (3) to a second data processing device (1) via a data network. Said call contains the address of the appliance and a file containing the allocable variables of the appliance. The address (10) for identifying the appliance (2) is extracted in the second data processing device (1) and information of the appliance (2) is accessed via the standardised interface (9) of the appliance (2) by means of the address extracted in the second data processing device (1). The second data processing device receives the variables to be requested, replaces the parameters in the file with the corresponding variables of the appliance, and transmits the file almost as an echo server to the first data processing device.
