    Abstract: Method for forming plastic preforms into plastic containers, wherein a plastic preform is introduced into a blow mould and is expanded into a plastic container by being applied by a flowable medium, wherein the plastic preform is applied by at least two different pressure levels and wherein furthermore preferably a rod-like body is introduced into the plastic preform, in order to expand the plastic preform in its longitudinal direction, wherein a pressure curve and/or a movement curve of the rod-like body being determined by a measuring device during the expansion process, wherein least one of the curves is evaluated by means of a processor device and at least one point or region of this curve which is characteristic of the course is determined.

    Abstract: The disclosure relates to a method for controlling a container treatment system, for example a blow molding machine, for producing containers from preforms, wherein the method comprises: providing a main agent comprising a plurality of sub-agents, each sub-agent being assigned to a container type or a preform, a target parameter set for controlling the container treatment system and a group of target values for a controlled variable being provided for each sub-agent; carrying out a determination of a characteristic of a preform; evaluating a result of the determination and automatically selecting a corresponding sub-agent from the plurality of sub-agents based on the evaluation; and using the corresponding sub-agent for controlling the container treatment system. The disclosure further relates to a device comprising a container treatment system and a control device for carrying out the method.
