Abstract

The invention relates to a method for the automatic control of batch processes by means of a process control in which the automatic control programs access individual control modules, wherein a) the control instructions and parameter definitions contained in the partial formulations or phases of the formulation program are stored in a separate program level for the activation, interlocking and switch-on blocking of actuators in the field, b) in the separate program level, the control instructions and parameter definitions for each actuator to be activated are collected actuator by actuator and, if appropriate, logically combined, and c) the currently effective activations, interlockings and switch-on blockings are output, actuator by actuator, to the process operating and monitoring system.
