Abstract

Data transmission and processing system with at least one input user (1), with a control unit (4) for the reception and the processing of data of the input user (1) and a transmission device (3) of data between the input user (1) and the control unit (4). The input user (1) cyclically makes available the input data values (Z0, Z1 . . . ZX) for retrieval, and the transmission device (3) cyclically calls up the input data values (Z0, Z1 . . . ZX) and transfers them to the control unit (4), to be sent after processing to at least one output user (2). A parameterization device (5) with a monitoring switch (12, 15) is provided at the input user (1) to mark the input data values that characterize critical states as critical data values (FZ1). In the case of the presence of such critical states, only the associated critical data values (FZ1) are made available henceforth for transfer and are transmitted until it has been determined with certainty that the control unit (4) has received the critical data values (FZ1).
