System for automating the control and regulation of machines and systems in the plastics industry

摘要

A system for automating the control and regulation of machines and systems in the plastics industry, in particular for blow molding machines, having programmable logic controllers (PLC), via which control and regulation functions of the machines and systems can be implemented as desired. The programmable logic controllers (PLC) have at least one operating and monitoring device and a local bus (user platform), and are further provided with digital technology blocks (10) which simulate individual electric circuit components and which can be used to implement the desired control and regulation functions in a modular fashion. The digital technology blocks (10) are connected to one another and to the user platform via data interfaces.
