IO-Link

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.

For this reason a lot of well-known manufacturers from the field of automation have come together and developed a fieldbus independent communication interface for sensors and actuators:
IO-Link.

Compatibility with existing technologies was the primary objective during development in order to guarantee investment protection.
