Abstract: A method includes determining the value of a plurality of selected process variables. Preferably, the respective current value of each selected process variable or a variable derived therefrom is compared with one or more reference values, and in each case at least one deviation or at least one rate of change is determined. On the basis of the determined plurality of deviations and/or rates of change, a stability of a current process state is determined. A computing unit visualizes a process states determined for different points in time and/or cycles by a chart such that a trajectory of the stability of process states for a predetermined period of time and/or over multiple cycles is visible in the chart. The computing unit visualizes a reference that, at a certain point in time, at least one factor was existing which is relevant for an evaluation of the result of the stability's trajectory.

Abstract: A method for automatic monitoring of a production process includes automatically determining a value of an indirect process quantity from at least one value of a process quantity. From the determined value, a preliminary reference value is determined, and a preliminary reference value is respectively allocated to a reference quantity. It is checked whether the preliminary reference value lies within a range of reference values permitted for the associated reference quantity. If not, the preliminary reference value is transformed into the permitted range of reference values and the transformed value corresponds to a limited reference value. Otherwise, the limited reference value corresponds to the preliminary reference value. It is checked whether at least one value of a monitored process quantity of the current production process represents an anomaly with regard to the limited reference value of the reference quantity, and/or a composite reference value of one composite reference quantity.
