Abstract: A non-transitory computer readable medium storing computer code which, when executed by a computer, causes the computer to access and activate software applications of accredited electrical power units by using personal access data that are used for automated access to the software applications of the accredited electrical power units and are held for this purpose in access data storage, and to perform image capture and image evaluation of graphical representations that are available, having been generated by the software applications, during the automated access to the software applications of the accredited electrical power units. The image evaluation ascertains status data of the accredited electrical power units and stores the status data in a status data memory and/or transmits the status data to a controller.
