The BIS-L Pallet RF ID System combines long-range sensing performance and new, inexpensive data carriers to fit the needs of a range of pallet-based production operations. Ideal for palletized assembly, the system has a read-write range of 24 to 100 mm, and is compatible with existing 125 kHz systems. The system consists of three main components; a read/write head, a data processor, and an innovative, wafer-thin, low-cost data carrier family. The new 1.6 mm thick data carriers are rugged enough to be permanently installed on pallets. The carriers are available in 20, 30, and 50 mm diameters with each size available in 40-bit read-only and 192-byte read/write versions. Data processor communication options include Interbus, Profibus, and Devicenet. The system is designed to eliminate false data and increase over-all dependability. Every carrier is prescreened during manufacture to be within a certain bandwidth for assured data transfer. During operation, the carriers' real-time communication parameters are redundantly monitored to ensure reliable information. Data communications errors at the edge of sensing envelope are eliminated with a sensing pattern designed with a read/no read cutoff for maximum system information accuracy.
