The invention relates to a method for operating a data network (20), comprising a number of terminals (2a, b, c), exchanging data with each other and supplied by at least one network node (11) or a least one of the terminals (13) having an internal supply with a supply capacity at a given nominal voltage level. A simplified and flexible priority based control of the network operation is achieved, wherein the terminals (12a, b, c) are arranged in categories with different priority levels and on the voltage level dropping below the nominal value with a dropping voltage level, the terminals (12a, b, c) are switched off in a sequence given by the priority thereof the terminal with the lowest priority being the first to be switched off. |
