IO-Link is the first standardized IO technology worldwide (IEC 61131-9) for the communication with sensors and also actuators. The powerful point-to-point communication is based on the long established 3-wire sensor and actuator connection without additional requirements regarding the cable material. Hence, IO-Link is no fieldbus but the further development of the existing, tried-and-tested connection technology for sensors and actuators. The IO-Link technology is managed by IO Link and PNO, a global trade and standards development organization.
