Contrinex’s Low-cost IO-Link RFID Prevents Expensive Hose-coupling Errors

Hose-coupling stations are common in the bulk handling of fluidizable materials and Contrinex's low-cost IO-Link RFID system provides a low-cost way of verifying the correct outlet/hose combination is used.

Bulk-handling hose-coupling stations are commonly used in food manufacturing plants to connect several material sources, typically silos or storage bins, to multiple processing machines, like mixers. Their use, however, introduces the risk of expensive errors if an input hose is connected to the wrong coupling.

A Contrinex IO-Link-enabled read/write module (RWM) is mounted beside the latching mechanism of each coupling to read RFID transponder tags on the input hoses. The RFID tags are mounted within each hose coupling and blanking cap to identify the mating parts uniquely. Blanking caps also carry unique RFID tags to confirm that unused outlets are closed with their cap. - This allows the individual outlet/hose combinations to be verified at the time of connection.

IO-Link-enabled Read-Write modules (RWMs) and RFID tags from Contrinex proved ideal for this application. An IO-Link enabled RWM, mounted on each outlet pipe, is connected to a plant-wide control system via two low-cost industry-standard 8-way IO-Link master hubs.

Contrinex IO-Link RWMs are configurable to operate in one of two discrete modes: IO-Link mode allows remote communication via the standard protocol. If local, non-networked control is preferred, the ’standard I/O mode’ (SIO) allows the device to function as an intelligent, presence-sensing sensor. Process engineers can switch RWMs between modes either remotely, using the IO-Link protocol itself, or locally, using a pre-configured ‘Master’ RFID tag, which is simply placed on top of the RWM during the RWM startup process.

With sensing distances up to 60 mm, robust M18- and M30-threaded metal housings and integral M12 connectors, Contrinex RWMs are ideally suited to the environment of a busy industrial processing plant. They are compatible with all ISO/IEC 15693-approved RFID tags, allowing designers ultimate flexibility and excellent value for money.
