Abstract: A telecontrol arrangement observes and/or controls an installation. The telecontrol arrangement is set up to communicate with field devices of the installation and with a control center arrangement. In order to specify a comparatively flexible telecontrol arrangement which can be adapted to change intended purposes with a smaller amount of effort, provision is made for the telecontrol arrangement to be formed in a data processing cloud.

Abstract: A method evaluates power engineering data using a data request that is transmitted to a coupling device by a first communication link. The coupling device is used to convert the data request from a coupling data format into a further data request that is specific to an energy engineering device in a device-specific data format. The further data request is transmitted to the power engineering device by a second communication link. The power engineering device transmits its power engineering data, requested by the further data request, to the coupling device by the second communication link. The power engineering data are in a data format that is specific to the power engineering device, and the coupling device converts all the power engineering data requested by further data requests into a data response in the coupling data format and uses the first communication link to transmit them to the evaluation device.
