摘要：The invention relates inter alia to a method for protecting, controlling ormonitoring an electrical switchgear or power supply station (10). According to saidmethod, a field device (20), especially a protective device, is used to generate datatelegrams (D) that relate to the status of the switchgear or power supply station, and thedata telegrams are transmitted to a higher-order command level device (40). Accordingto the invention, a second field device (30) is redundant with respect to the first fielddevice and is used to check whether the first field device (20) is operative by operating acommunication link (60) between the two field devices via which link the second fielddevice is informed of the functional status of the first field device. The second field deviceceases forwarding own data telegrams (D) to the higher-order command level device ifthe first field device is operative, else it transmits data telegrams relating to the status ofthe switchgear or power supply station to the higher-order command level device.
