<p>An apparatus and method of restoring the position and status information for each of a plurality of workpieces in a workpiece processing system is disclosed. As workpieces are loaded, processed, and unloaded from a workpiece processing system a sensor assembly tracks the location and status of each workpiece. The sensor assembly provides such status and location information to a processor. The processor allows an operator to overwrite or enter new status and location information while also providing such information to a non-volatile storage system. Whenever, the operation of a workpiece processing system is catastrophically interrupted and all previously entered variable erased from the processor, the present invention allows an operator to recall the previously, and periodically updated data from the non-volatile storage system and reset processor parameters. Additionally, the operator may determine which workpiece(s) are salvageable and may resume processing the salvaged workpieces. Additionally, the present invention allows the operator to recall at any time the location and status of any workpiece.</p> |
