Abstract: The invention relates to a device and method for classifying two-state variables of a cyclically-operating system comprising subunits. The inventive method comprises the following steps: a recording step consisting in recording dated state changes noted for each of the variables during a determined time T; a calculation step consisting in using the aforementioned dated state changes in order to determine, for each of the variables, (i) the different durations (D1) between two consecutive passages to a first state (E1) and (ii) the different durations (D2) between two consecutive passages to a second state (E2), such as to create duration lists (LD1) and (LD2); and a processing step consisting in, for each variable, comparing the different duration lists (LD1) and/or (LD2) to the different duration lists (LD1) and/or (LD2) for the other variables and the number of occurrences thereof, such as to classify said variables into groups, whereby each group corresponds to at least one of the subunits of the system.

Abstract: An industrial process (2) is simulated in which the value of each physical magnitude P.sub.i characteristic of its state is varied at a rate of change V.sub.i that is a function of the state of control signals (3) emitted by an automatic controller (1), and which reports its state to said controller by means of state signals (4) which are emitted by sensors as a function of the values of the respective physical magnitudes that they monitor. For each physical magnitude P.sub.i, the time interval .delta.t.sub.i is determined during which the value of the physical magnitude can change without any of the sensors monitoring said physical magnitude P.sub.i changing state. Thereafter the value of each of the physical magnitudes P.sub.i is updated by incrementing its value by the product of the corresponding rate of change V.sub.i multiplied by the smallest of the above-determined time intervals .delta.t. Finally, after updating the sensors monitoring each of the physical magnitudes P.sub.i, a parameterizable length of time is allowed to elapse before repeating the method. The simulation method is used for testing the logical operation and the timing of a controller, such as an industrial programmable controller.

Abstract: A device and a method for the analysis and troubleshooting of a system, based on the use of a model of the system, with application in particular in the area of industrial installations controlled by automatic control systems of the programmed or wired logic type. The method includes a stage for initialisation of the model, and a stage for the creation of a list of discordant variables whose value in the system differs from that predicted by the model. For each of the variables belonging to a discordance list, an initial list of suspect variables, suspected of having generated the discordant value, is created, and then a restricted list of suspect variables is obtained by filtration of the initial list.
