Abstract: The invention relates to an electric field device (1) comprising a computer-controlled least one input/output module (3a-3f) data inputs and/or data outputs. The central control module (2) and the at least one input/output module (3a-3f) are connected to one another via a data bus (4). In order to design a field device of this type as to enable a comparatively easy adaptation of the device software of the field device to its quantity schedule, the invention provides that the type and number of the module parameters of the at least one input/output module (3a-3f), which indicate data inputs and outputs, are provided by this at least one input/output module (3a-3f) in order to query the central control module (2). The invention also relates to a method for configuring the electric field device (1).

Abstract: Method and arrangement for sensing and digitally transmitting analog output measurement variables of a plurality of transformers The invention relates to a method and an arrangement for sensing and digitally transmitting analog output measurement variables of a plurality of transformers to a protective unit or panel unit in which digital measurement variables corresponding to the output measurement variables are transmitted to a data concentrator in which a telegram is formed with the digital measurement variables and a predetermined minimum sampling rate. So that analog output measurement variables of transformers can be acquired, collected and transmitted to protective units or panel units at high speed and in synchronism with one another, the analog output measurement variables are converted into the digital measurement variables (Md) and transmitted with a sampling rate which is higher than the minimum sampling rate by a factor (m).

Abstract: To develop a method according to WO 01/45232 in such a manner that it supplies good results in every case, in a method for detecting and digitally transmitting measured analog output values of a number of transducers to a protection or field device, the measured analog output values of each transducer (ECT1 . . . EVTBB) are converted into measured digital values (Md) at a sampling rate which is higher by a factor (m) than the minimum sampling rate, and are transmitted, the factor (m) being an integer divider of the number (n) of the filter coefficients of in each case one FIR filter (FIR) with filter coefficients of the value 1 in a data concentrator (26) for each transducer (ECT1 . . . EVTBB). The measured digital values (Md) are transmitted as a message to a data concentrator and from buffers (Buf1) associated with each transducer (ECT1 . . .
