The invention relates to a method and configuration for testing digital protection devices in which a data processing energy supply network is emulated by means of pulsed output of digital current and voltage signals. To this end, utilizing one such method, corresponding currents and voltages are constructed and supplied to a protection device which is to be tested. In order to test protection devices as realistically as possible with comparatively simple data processing equipment, the fetched out digital current and voltage signals (J', U') are first buffered in succession at the beginning of the testing of the protection device (6). After achieving a predetermined consistency of the buffered signals (Iz, Uz), the respective oldest buffered signals (Iz, Uz) are read out in a clock-pulse manner and most recent fetched out signals (J', U') are buffered. In the occurrence of a tripping signal, reading out is continued in a pulsed manner and data processing network specific digital current and voltage signals are fetched out and buffered.
