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.

A method of emulating machine tool behavior for a programmable logic controller logical verification system for manufacturing a motor vehicle, said method comprising the steps of:
- constructing a mechanical model;
- viewing motion of the mechanical model in a motion viewer;
- determining whether the motion of the mechanical model is acceptable;
- 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.
A method of emulating machine tool behavior for a programmable logic controller logical verification system for manufacturing a motor vehicle, said method comprising the steps of:
- constructing a mechanical model;
- generating CAD transformational arrays for motion in the mechanical model;
- constructing a motion file based on the mechanical model and the CAD transformational arrays;
- viewing the motion of the motion file in a motion viewer;
- determining whether the motion of the mechanical model is acceptable;
- replicating the motion previously defined with motion commands initiated by 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 to the accepted motion.
