Abstract
Certain exemplary embodiments comprise a method comprising a plurality of activities comprising via a graphical editor running on a Human Machine Interface comprising a first embedded operating system, providing a plurality of set points related to a process to a programmable logic controller. The method can comprise, via the programmable logic controller, automatically controlling the process responsive to information received from the graphical editor.
Claims21
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.

A plastics blow molding system comprising:
- a human machine interface comprising a first embedded operating system, said human machine interface comprising a graphical parison editor, the graphical parison editor configured to interpolate 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, and said parison editor is further configured to modify at least one of said plurality of set points during run time of the graphical parison editor;
- and
- a programmable logic controller communicatively coupled to said human machine interface, said programmable logic controller comprising a second embedded operating system, said programmable logic controller configure to:
- receive the plurality of set points for parison profiling via a network,
- control a plastics blow molding process simultaneously across a plurality of parison heads based on the plurality of set points, and
- during the plastics blow molding process, automatically respond to information related to a modification to at least one of said plurality of set points made via the graphical parison editor and received from the graphical parison editor to control the plastics blow molding process based on the received information;
- 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.
