ABSTRACT:
Apparatus is connected by way of a serial communication link to at least one computer-based elevator controller in order to monitor the diagnostic output of each connected controller. The diagnostic output of a controller is determined in a manner by which the elevator system is modeled as normally operating sequentially from state to state in a closed loop sequence of linked operating states. Any deviations from this sequence generate diagnostic messages that are communicated from the controller to the monitoring apparatus. Also communicated are the last to occur of a plurality of parameter signal state changes. The monitoring apparatus processes the diagnostic signals for visual and/or hard copy display to interested elevator personnel in a meaningful way. Further, the monitoring apparatus provides a plurality of signals to the elevator controller indicative of corresponding reference standards that the elevator controller utilizes in determining the occurrence of certain elevator event conditions.
