Identifying and visualizing faults in PLC-based manufacturing systems

摘要

Textual fault messages in PLC-based manufacturing systems are supplemented by automatically displayed sets of information that allow an operator to quickly identify, recognize and visualize components responsible for producing faults. Visual display of stored computer generated images showing system components and tooling allow the operator to visually pinpoint the exact component responsible for the fault, and its location within the manufacturing system. Stored information associated with the component producing the fault, such as installation date, vendor sources, replacement part inventory, programming logic and editing software, is also automatically recalled and displayed along with the fault message to aid fault diagnosis and correction.
