Error-proofing through the clever application of sensors and RFID systems is as important as the overall logic and structure of the production process itself. Sensors and RFID systems provide vital links in a supply chain and are regarded as the most effective ways of reducing cost and improving manufacturing processes. Today, sensors are considered the primary control components on the line. They tell the PLC how well things are happening and if the products and parts are within spec. RFID, within and between islands of automation, provides a way of tracking not only what has happened, but what has gone right. The RFID system records where something has gone wrong, and what needs to be done to correct the problem. It also ensures that the right product is queued in the correct sequence and delivered at the right time—time after time. This paper will give you an idea of how these technologies can be implemented on your production line.
