Abstract
A field device for monitoring an operating state of an electrical engineering installation, in particular a transformer substation or a switching substation, having an evaluation device, which evaluates input signals, which are present on the input side and relate to the electrical engineering installation, on the basis of predetermined criteria and, on the output side, generates an output signal, which characterizes the respective evaluation result. An identification can be input to the evaluation device which specifies the hierarchical level to which the evaluation device is assigned. The evaluation device is designed such that, after a connection to a data transmission network, it automatically produces a data link with all other evaluation devices connected thereto or with all other evaluation devices connected thereto of a predetermined type which belong to a directly lower-order or a directly higher-order hierarchical level. The output signals of hierarchically lower-order evaluation devices are processed as input signals and dedicated output signals are passed on to hierarchically higher-order evaluation devices.
