From receipt of goods via picking to shipping – even complex material flows can be controlled by smart RFID technology. To achieve this, each carrier (tray or pallet) is labelled with an RFID tag that contains identification and controls information such as transport destination and specific routing information.
Additional information like a purchase order number can be saved on the tag as well. This data is read by the RFID readers and directly transmitted to the PLCs in order to control the material handling equipment. Even at highest required throughput a material flow computer can be omitted.
All routing decisions are made directly at the equipment controls level, using locally available data. The local information processing reduces the workload of the communication networks.
The less complex IT solutions, and options for parallel and local tests, lead to considerably lowered project risks and easier commissioning.
