3.10. IO-LINK

IO-Link is developed by the IO-Link Consortium and is integrated in the Profibus User Organization. IO-Link is becoming increasingly widespread in Europe.

The brand name IO-Link refers to a communication system to con- nect sensors and actuators. Along with AS-Interface, it provides another option for the simple connection of sensors/actuators to a higher-level fieldbus. IO-Link is standardized under the designation Single-Drop Digital Communication Interface for small sensors and actuators (SDCI) and, unlike all other fieldbuses presented here, is not a bus system but a form of point-to-point communication.
