Patent ID: 7844751

Claim:
Data transmission and processing system, comprising: at least one input user ( 1 ); a control unit ( 4 ) for the reception and the processing of data of the input user ( 1 ); and a transmission device ( 3 ) for data between the input user ( 1 ) and the control unit ( 4 ); where the input user ( 1 ) makes available cyclically input data values (Z 0 , Z 1 . . . Z x ) to be retrieved and the transmission device ( 3 ) cyclically calls up the input data values (Z 0 , Z 1 . . . Z x ), which are transmitted to the control unit ( 4 ), to be sent after processing, as output data (A 0 , A 1 . . . A x ) to at least one output user ( 2 ); characterized in that parameterization means ( 5 ) with a monitoring circuit ( 12 , 15 ) are provided at the input user ( 1 ), to mark input data values that characterize critical states, as critical data (FZ 1 ), and, in the case of the presence of such critical states, only the associated critical data values (FZ 1 ) will henceforth be made available for transfer, and transmitted until it is determined with certainty that the control unit ( 4 ) has received the critical data values (FZ 1 ).
