Rockwell ControlLogix PLCs control the system in a warm standby backup configuration. One set of PLCs communicates with field devices and motor controllers using distributed Flex I/O over ControlNet. Other system components such as baggage dimensioners and scanners, VFDs, bar code scanners, and security systems are integrated with the PLC controllers using Ethernet I/P and in one case a custom Ethernet/serial interface.

Wonderware System Platform HMI software provides real-time conveyor status and equipment alarms to operations, and Microsoft Reporting Services provides detailed reports on both bag and equipment history. The entire system was successfully commissioned with no interruption to the normal flow of traffic through the airport.

Passengers are the big winners from this system. No longer must passengers hand-carry their luggage to the TSA baggage screening checkpoint, as the new system ensures their safety while traveling. Airport personnel also benefit from a reliable system built on modern technology. The system provides a high level of visibility to maintenance personnel and TSA personnel who work together to quickly and safely transfer passenger luggage from the ticket counter to the right aircraft.
