IO-Link is a manufacturer-independent digital interface. The properties of intelligent sensors are made fully usable by IO-Link, thus opening up new paths in automation technology (keyword Industrie 4.0).
This offers several advantages in practice: The point-to-point connection provides fieldbus functionality and allows continuous communication to the sensor level. The uniform software in the control system allows for quick operation. The user is abe to change parameters such as e.g. zero point, travel direction or resolution. The simple wiring with 3-wire unshielded cables results in significant cost saving.
In addition to the position information, further information such as status or diagnostic messages are exchanged. Since the setting parameters are stored centrally, errors in the control loop can be quickly located and the sensor exchange is fast. Finally IO-Link brings a cost reduction that benefits both automation and mechanical engineering.
