The new communication standard for intelligent factory automation: IO-Link Wireless from Balluff

Wireless data transmission

Balluff: With its wireless IO-Link variant, Balluff is expanding its portfolio with a fast, reliable and flexible solution – while guaranteeing consistent system integration and compatibility. IO-Link Wireless is used wher-ever classic data transmission was previously impossible or only possible with difficulty.

As a digital interface, the IO-Link communication standard enables fieldbus-independent point-to-point connection and seamless communi-cation between intelligent sensor and automation system. The technolo-gy is thus an essential building block for the factory of the future. With the introduction of IO-Link Wireless, Balluff is now adding a wireless solution to its own extensive IO-Link portfolio. "Whether in inaccessible places, in robotics or in highly dynamic transport systems: IO-Link Wireless prom-ises an even more flexible and sustainable application – while maintain-ing system integration and compatibility," says Balluff Product Manager Michael Zahlecker. Customers already using IO-Link can easily config-ure IO-Link Wireless via the integrated web server.

Instead of using cables, the wireless master receives the sensor data by radio via a bridge or hub. "The new wireless standard meets the high demands of factory automation," says Zahlecker. Easier planning and installation, greater flexibility and mobility, and the elimination of plugs or cables are among the major advantages over a wired system. At the same time, IO-Link Wireless can be used worldwide without a license in a frequency range of 2.4 - 2.483 GHz. "When developing IO-Link Wire-less, high reliability was of paramount importance to us," explains Zahlecker. A latency of 5ms and an error rate of 10-9 thus enable direct connection as well as fast and reliable data transmission. A further plus point is the problem-free scaling and extended integration of up to 40 devices.

The wireless IO-Link variant is used in dynamic, fixed and mobile appli-cations: On transport systems with high speeds, compatible sensors can thus be placed directly on the carriage for more precise monitoring. When changing tools on a gripper, the absence of cabling enables data transmission in confined spaces. This also applies to milling machines, which offer little space for sensors but require high process reliability. Here, the new system scores with its robustness. "Since there is no need for cabling, IO-Link Wireless can also be used to install condition moni-toring sensors in monitoring systems, even in inaccessible places," ex-plains Zahlecker, "making the system ideally suited for retrofitting exist-ing solutions." In addition to the new IO-Link wireless standard, Balluff offers various solutions for contactless data and power transmission and is constantly expanding its own wireless portfolio. "Using wireless tech-nology, we want to unleash industrial communication," says Hubertus Breier, Head of Technology at Balluff, describing the benefits of wireless solutions in industrial communication. "Thanks to the IO-Link wireless standard, we can now collect data in applications, for example, where this was either technical-ly impossible or too costly before."
