METHOD AND DEVICE FOR VISUALIZING OR EVALUATING A PROCESS STATUS

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.
