Abstract
An apparatus for controlling and/or regulating process parameters of an installation such as a building automation installation has at least a first decision table and preferably a second decision table. The decision tables have rules with which a priority is associated. By evaluating the rules of the first decision table, on the basis of the state of a sub-system of the installation, a further state value is ascertained and fed to an input of the second decision table. The state of a further sub-system of the installation is altered by evaluation of rules of the second decision table. The decision tables can be represented for an installation operator in a picture screen window.
