Abstract (en)
[origin: WO2020173701A1] The invention relates to a method for monitoring an industrial plant (100), to a computer program product, and to an industrial plant (100). The industrial plant (100) comprises two parts (100a, 100b). In a first part (100a) of the industrial plant (100), in particular a paper machine, first parameters (x1,...,xn) are provided. The industrial plant (100), particularly designed as a paper machine, is used to produce and/or process a fibrous material web (1). Second parameters (y1,...,yn) are provided in a second part (100b). The parameters (x1,...,xn,y1,...,yn) are stored, preferentially as time series (16a,...,16n,17a,...,17n). In the case of a web break in the second part (100b), the second parameters (y1,...,yn) are first analyzed for a second anomaly. If no second anomaly can be detected, the first parameters (x1,...,xn) are analyzed for a first anomaly. During the analysis, the parameters (x1,...xn, y1,...,yn) which were stored in a time range before the web break (F) are preferably examined. If a first or second anomaly is detected, these, and optionally measures to avoid such web breaks (F), are displayed to the user. Optionally, the first parameters x1,...,xn and/or the second parameters y1,...,yn can be set so as to avoid future web breaks F.
