An operating device (PC) is connected via a separate operating interface (E/A1) to the relevant electrical installation (e.g. DUE1). On defined control signals being output by this operating device, an operating routine, which runs as a background routine during operation, is activated in the respective electrical installation. On a first defined control signal, in the course of the operating routine, a data block, which contains state information about the states of external interface lines or test loops of the respective electrical installation, is transmitted to the operating device (PC). This state information is thus brought into the operating device for display. On at least a second signal of the defined control signals, in the course of the operating routine, the appropriate test loop is activated, and defined test information about it is then transmitted. <IMAGE> |
