Errors in the seat order are very costly, requiring a complete line shut down. DMC's system utilizes the RFID tags already located on the seats to ensure that this never happens. The RFID tag in each passing seat is read and the sequence number is transmitted to the PLC controlling the transportation of the seats to the assembly line. If an out-of-order car seat is found the PLC will stop transportation, alert the operator, and the car seat will not be introduced onto the assembly line. The system is flexible enough to allow for introduction of car seats that are out of order (for special car builds) and to stop the machine for a particular sequence number.
