  • Data collector control system with automatic communication port switch
    Publication number: 20070213862
    Abstract: A data collector control system for semiconductor manufacturing comprises a data collector and a automatic communication port switch control circuit. The control system is placed between an equipment and an equipment automation programming (EAP) system. The data collector processes and transmits communication messages between the equipment and the EAP system while the data collector operates normally. The communication messages between the equipment and the EAP system are transmitted through the control circuit instead of the data collector while the data collector operates abnormally.
