The popular actuator/sensor communication standard IO-Link is now also available as a wireless version called IO-Link Wireless. By omitting cables, IO-Link Wireless offers considerably more flexibility, less wear and better scalability compared to its wired counterpart. At 10e-9, the packet error capability (PEP) of IO-Link Wireless is comparable to the PEP of wired solutions and thus has a significantly lower probability of error than other wireless protocols such as Bluetooth or Zigbee. With IO-Link Wireless, up to 40 actuators or sensors (so-called Devices) with a maximum latency of 5 ms can be connected to an IO-Link Wireless Master. The maximum distance between Master and Device is up to 20 meters. The simultaneous operation of WLAN systems is also possible. Thanks to backwards compatibility, users do not have to replace their existing IO-Link system when installing IO-Link Wireless, but can integrate IO-Link Wireless seamlessly into their existing, wired system. KUNBUS Development Toolkits enable device manufacturers to enter the world of IO-Link Wireless quickly and easily. The toolkits are available for both IO-Link Wireless Master and Device development. Technologically, KUNBUS has chosen the SimpleLink(TM) CC2650 microcontroller from Texas Instruments for IO-Link Wireless. Compared to other microcontrollers on the market, the CC2650 offers high performance at very low power consumption. This allows potential applications with energy self-sufficient sensors, which are also
covered by the IO-Link wireless standard. Thanks to its multi-track capability, the CC2650 as an IO-Link Wireless Master module can control up to 5 tracks with a total of 40 devices. For a seamless integration of an IO-Link Wireless Master into the superordinate fieldbus or industrial Ethernet level, KUNBUS also offers various interface solutions for all common industrial network protocols.
