IO-Link

IO-Link is a fieldbus-independent interface that ensures seamless communication down to the “last meter” at the field level. With IO-Link, sensors and actuators can be connected to the control system level via a cost-efficient, point-to-point connection on a standard, unshielded three-conductor cable. Being an open interface, IO-Link can be integrated into all common fieldbus and automation systems.

The international IO-Link standard (IEC 61131-9) enables central fault diagnosis and localization down to the actuator/sensor level. Further information, such as parameters or diagnostic messages, are exchanged in addition to process values. IO-Link devices can even be adapted to the respective production requirements via the control system during operation.
