Abstract

A method for operating a wireless field-device network, comprising: wirelessly transmitting a process variable and an expected remaining running time from each field device to the other field devices within a field-device network so that in each field device the process variable and the expected remaining running time of the other field devices of the field-device network are stored; activating a second radio module of that field device which has the highest expected remaining running time, and deactivating the second radio modules of the other field devices within the field-device network; wirelessly transmitting the process variables of all field devices of the field-device network stored in the active field device, or at least a subset of the stored process variables, to the superordinate unit, which is not part of the field-device network, by means of the second radio module of the active field device.
