Tag-based system saves PLC and money! How the Industry 4.0 philosophy can be implemented in specific projects was recently demonstrated by Kirschenhofer Maschinen GmbH in a project for Britax Römer Kindersicherheit GmbH. Kirschenhofer implemented a tracking system for child seats without any kind of higher-level controllers or central databases and using an RFID tag on the product as the data pool. This tag contains the sequence of the assembly stations and documents all production steps. This ensures quality and makes it possible to later identify the product quickly and easily even in its packaging – at any location and without any access to a database. The successful project is based on the connection Kirschenhofer implemented from Turck's TBEN-S multiprotocol RFID I/O modules to the Labview system development software from National Instruments.
