IO-Link vereenvoudigt productie versnellingsbak

Bij de versnellingsbakproductie van een Chinese toeleverancier van auto-onderdelen bewijst Turck dat haar IO-Link oplossing garant staat voor een eenvoudige, snelle en efficiënte signaaltransmissie.

Een Chinese fabrikant van versnellingsbakken maakt gebruik van Turck's TBIL IO-Link hub voor het aansluiten van honderden sensoren en actuatoren in de productie. Op elke van deze verdeelboxen kunnen tot 16 sensoren of actuatoren aangesloten worden via IO-Link. Deze oplossing bespaart niet alleen tijd voor het assembleren van multicore kabels, maar reduceert ook kosten. Deze oplossing wordt gecomplementeerd met Turck's BL20 Profibus gateways met IO-Link master modules. Naast de schakelsignalen worden ook de RFID-data en de analoge signalen overgebracht naar de PLC.

  • Voordelig : 26 TBIL I/O-hubs zorgen voor 26-voudige besparingen op multicore-kabels en hun montage

  • Naast honderden schakelsignalen brengen twee BL20-systemen RFID-data en analoge signalen naar de PLC.

Many sensors in gear production

Several magnetic field sensors on a production line of differential gears detect the positions of pneumatic cylinders and clamps, while proximity switches detect components of the differentials themselves. There are also many actuators such as air valves, solenoid valves and other devices, which perform the commands of the controller.

Multicore cables and passive junctions failed

Initially, the customer wanted to connect the signals of sensors and actuators to the fieldbus gateways in the control cabinet using passive junctions and multicore cables. But the costs of the cable lengths and the extensive wiring effort involved had a negative effect on the overall cost. Many cables for the passive junctions would have had to be prepared manually and then connected again to the I/O modules in the control cabinet. Commissioning would have been particularly prone to errors as well as being time consuming. The solution would also have been very expensive and difficult to maintain.

IO-Link solution fast and efficient

Turck could offer a space saving solution based on a BL20 Profibus gateway for the control cabinet in conjunction with IO-Link master modules. Turck's IO-Link compatible TBIL junction boxes are ideal for connecting the sensors and actuators in the field. These I/O hubs use IO-Link to bring up to 16 binary signals to the IO-Link master via a standard sensor cable. As the TBIL I/O hubs offer protection to IP67, they can be mounted directly in the field as close as possible to the sensors and actuators. IO-Link is a digital protocol that allows the use of standard three-wire cables, which eliminates the need for any expensive shielding and lengthy cable commissioning.

If any faults occurred later, however, maintenance was simple thanks to the use of IO-Link. The location of faults can be identified right down to the individual field device and differentiated between a wire break or a short circuit. The central configuration of the entire system from the controller ensures the central availability of all relevant information. This simplifies both maintenance and documentation.

Analog signals via IO-Link

The customer realized that he would also be able to connect all measuring sensors for pressure and temperature with IO-Link as long as they have an interface. Special analog input modules are thus just as unnecessary as the expensive shielded cables for analog signals.
