  • Method of emulating machine tool behavior for programmable logic controller logical verification system
    Patent number: 8135567
    Abstract: A method is provided of emulating and visualizing machine tool behavior for a programmable logic controller logical verification system for manufacturing a motor vehicle. The method includes the steps of constructing a mechanical model. The method also includes the steps of viewing motion of the mechanical model in a motion viewer and determining whether the motion of the mechanical model is acceptable. The method further includes the steps of replicating the motion previously defined with PLC code if the motion of the mechanical model was acceptable and using the accepted motion of the mechanical model to compare the behavior of the PLC code relative to the accepted motion.

  • Method of logical modeling of operator interaction with programmable logic controller logical verification system
    Publication number: 20020069045
    Abstract: A method is provided of logical modeling operator interaction with a programmable logical controller logic verification system. The method includes the steps of constructing a flowchart of interaction of an operator in a workcell part and testing whether the logic of the flowchart is correct. The method also includes the step of using the flowchart to test PLC code to build the workcell if the logic of the flowchart is correct.
