Most sensors and actuators today are already equipped with microprocessors, which can be used for parameterization, storing configuration data, and controlling indication. The obvious next step is to overcome the bottleneck of the binary standard interface and make additional functions centrally accessible for the automation system.
IO-Link is based on a point-to-point connection between the sensor/actuator and an interface module. Up to now, the binary connection was only designed for transferring switching information, but IO-Link now allows two bytes to be transferred normally in a 2 ms cycle via a combined switching status and data channel. Other information can be exchanged in addition to the process values, such as parameters or diagnostics messages. This enables communication with sensors and actuators down to the “last meter” to be established for universal communication.
