ABSTRACT:
A maintenance system for a machine (12) controlled by a programmable logic controller (14) having a memory (20) which stores input data received from the machine (12) and output data communicated to the machine (12). The maintenance system includes a computer (33) interfaced to the memory to be non-intrusive with respect to the programmable logic controller (14). The computer (33) is operative to monitor a state of the machine (12) over a plurality of manufacturing cycles, the state including at least a portion of the input data and the output data. The computer (33) is further operative to detect a fault condition for a component of the machine (12) based upon a state of a current manufacturing cycle and a state of a previous manufacturing cycle. A display device (32) is in communication with the computer (33) to alert an operator of the fault condition and to graphically display a location of the component within the machine (12) to facilitate a corrective measure by the operator.
