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. 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 m. 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 Master and Device development. Technologically, KUNBUS has chosen the SimpleLink 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.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 interface solutions for common industrial network protocols.
