Patent ID: 7953513

Claim:
A method for controlling a plastics blow molding process, the method comprising a plurality of steps comprising: via a graphical parison editor running on a human machine interface comprising a first embedded operating system, automatically interpolating between a plurality of master points and a plurality of set points for parison profiling, wherein said human machine interface generates said plurality of set points based on said plurality of master points; transferring to a programmable logic controller the plurality of set points for parison profiling, via a network; controlling the plastics blow molding process at the programmable logic controller simultaneously across a plurality of parison heads based on the plurality of set points; via the parison editor running on the human machine interface, modifying at least one of said plurality of set points during run time of the graphical parison editor to generate at least one modified set point; and during the plastics blow molding process, automatically responding at the programmable logic controller to information received from the graphical parison editor to control the plastics blow molding process based on the received information, the received information related to the at least one modified set point, wherein the programmable logic controller is communicatively coupled to, yet physically distinct from the human machine interface, and the programmable logic controller comprises a second embedded operating system; said first and second embedded operating systems comprising a plurality of machine-readable instructions that define a limited set of pre-defined functions that cannot be modified or added to by additional user-installed software.
