What is IO-Link?

IO-Link is the first worldwide-standardized IO technology (IEC 61131-9) for communicating from the controller to the lowest level of automation. Its interface can be used universally and is a fieldbus-independent, point-to-point connection that operates using an unshielded industrial cable.

What Does IO-Link Provide?

IO-Link transmits all sensor signals to the controller and, conversely, relays control data to the sensor/actuator level – this is how IO-Link integrates every sensor into the fieldbus level. It enables comprehensive, ongoing diagnostics and automated configuration of parameters via the controller.
