Abstract

A method for monitoring sequencing of a control recipe for a batch process, wherein the recipe comprises a plurality of recipe elements and is displayable on a display unit of a batch or operator system. In order to simplify the monitoring of the sequence of the control recipe a respective recipe-element-specific rule is created for each of the plurality of recipe elements, compliance with the respective recipe-element-specific rule is monitored for each of the plurality of recipe elements during run-time of the control recipe, each recipe element of the plurality of recipe elements is automatically classified into one of a plurality of problem levels if the respective recipe-element-specific rule for a respective recipe element of the plurality of recipe elements is not complied with, and recipe elements of the plurality of recipe elements that have been classified are displayed, together with the respective problem level, on the display unit in tabular form.
