IO-Link Communication Protocol

IO-Link is an industrial communication protocol for connecting sensors and actuators with automation systems. It was developed by the IO-Link community and is managed as an international standard (IEC 61131-9). IO-Link enables bidirectional communication and transmits both process data and device parameters.

IO-Link uses a point-to-point connection and can be integrated into various network topologies. It supports simple cabling via standard industrial cables and offers diagnostic functions as well as the option of automatic device parameterization.
