In the context of the Industry 4.0 initiative Cyber-Physical Production Systems (CPPS) or Cyber Manufacturing Systems (CMS) can be characterized as advanced networked mechatronic production systems interacting with the ambient Industrial Internet of Things (IIoT). In this strongly evolving technological environment appropriate communication technologies and standards play a vital role to let the manifold potential improvements in the production process become true. One of these standards is IO-Link. In 2016 more than 5 million IO-Link nodes have been produced and delivered, still gaining an increasing acceptance for the communication between sensors, actuators and the control level. There is also a steadily increasing demand for more flexibility in automation solutions, which often can be supported by wireless technologies. With the wireless extension for the IO-Link standard, which will be presented in this article, cycle times down to 5 ms could be achieved. The probability that this limit will be exceeded lies at 10-9. Also roaming capabilities, wireless coexistence mechanisms and the possibility to include battery-powered or energy-harvesting sensors with very limited energy resources in the real-time network were implemented. For system planning, setup, operation and maintenance standard engineering tools of IO-Link can be employed so that the backward compatibility with wireline IO-Link solutions can be guaranteed.
