IO-Link is easy 12.1 Overview of IO-Link technology IO-Link is an innovative communication technology for sensors and actuators defined by the PROFIBUS user organization (PNO). IO-Link is an international standard according to IEC 61131-9. It is based on a point-to-point connection between the sensors and actuators (slaves) and the controller (master).
