Data transmission and processing system with reliable acquisition of critical states
First Claim
1. 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 (Z0, Z1 . . . Zx) to be retrieved and the transmission device (3) cyclically calls up the input data values (Z0, Z1 . . . Zx), which are transmitted to the control unit (4), to be sent after processing, as output data (A0, A1 . . . Ax) to at least one output user (2);
characterized in thatparameterization 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 (FZ1), and,in the case of the presence of such critical states, only the associated critical data values (FZ1) 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 (FZ1).

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).

12. Method to ensure the reliability of the data transmission and processing of critical data values, which originate from the input user (1), the method comprising:
-
a) delivering, in a cadenced or cyclic fashion, input data (Z0, Z1 . . . ZX) to a given input user (1) of a plurality of input users; b) storing the input data (Z0, Z1 . . . ZX) for cadenced or cyclic retrieval; c) comparing the input data (Z0, Z1 . . . ZX) with the parameterization data for the purpose of detecting critical data values (FZ1); d) if no critical data values (FZ1) are detected, transmitting the input data (Z0, Z1 . . . ZX) to a control unit (4); and e) if critical data values (Z6=FZ1) have arrived, interrupting the storage in memory of the continually delivered input data and transmitting the critical data values (FZ1) to the control unit (4) until it is determined with certainty that the control unit (4) has received the critical data values. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19)
