A computerized machine control (CMC) diagnostic system communicates with a computerized machine controller that utilizes a control program to control the operation of a machine through the use of a plurality of digital channels. In general terms, the system includes a data acquisition component, a data storage component and a viewing component. The data acquisition component queries and acquires time-based transition data about the plurality of digital channels. The data storage component stores the acquired transition data in order to establish an historical pattern of the transition data that can be compared to currently acquired transition data. The historical pattern of transition data is established independently of the control program. Upon comparison of the current transition data to the expected, historical pattern of transition data, a determination about the operational status of the machine being controlled can be made. The operational status can then be displayed on the viewing component.

What is claimed is: 1. A computerized machine control (CMC) monitoring system, wherein said CMC controls operation of a plurality of digital channels under direction of a control program, said system comprising: a data acquisition component, wherein said data acquisition component is in communication with said CMC, and wherein said data acquisition component acquires transition data about said plurality of digital channels; a data storage component, wherein said data storage component is in communication with said data acquisition component, wherein said data storage component stores the acquired transition data to establish an historical pattern of transition data that is comparable to current transition data independent of the control program; and a viewing component, wherein said viewing component is in communication with said data storage component, and wherein said viewing component displays a sequence diagram of said historical pattern of transition data defined by a first average transition time to on, a second average transition time to off, and a duration time of an individual channel for substantially all of said plurality of digital channels on an individual basis and a sequence diagram of said current transition data. 2. The system of claim 1, wherein said historical pattern of transition data of the individual channel in said sequence diagram display is further defined by a statistical window about each of said first average transition time and said second average transition time. 3. The system of claim 1, wherein said first average transition time and said second transition time are calculated from a pre-selected reference data set. 4. The system of claim 1, wherein said sequence diagram of said current transition data and said sequence diagram of said historical pattern of transition data overlay each other. 5. The system of claim 1, wherein said sequence diagram include a substantially real-time scrolling cursor. 6. The system of claim 5, wherein said substantially real-time scrolling cursor stops scrolling at an instant of a downtime event. 7. The system of claim 1, wherein said sequence diagram of said current transition data is capable of displaying intermittent failures in said plurality of digital channels. 8. The system of claim 1, wherein said viewing component displays a digital channel identifier proximate said sequence diagrams, wherein said digital identifier is selected from a group consisting of: an imported name, a user entered name, and an address. 9. The system of claim 1, wherein said sequence diagrams provide analog channel data.
