Cabling interface for a production machine in the plastics processing industry and method for retooling such a production machine

A production machine in the plastics processing industry includes multiple cavities and multiple piezoelectric pressure transducers. At least one piezoelectric pressure transducer is arranged at each cavity and captures an internal tool pressure inside the cavity and returns an electrical charge signal for each internal tool pressure detected. A cabling interface conducts the electrical charge signal away from piezoelectric pressure transducer via an inner cable. Each of the inner cables can be connected electrically to the cabling interface via at least two different connection standards.
