Uninterrupted communication down to the last meter: the point-to-point interface IO-Link

Networking with IO-Link

IO-Link – more than just another interface

IO-Link is the smart concept for the standardized linking of switching devices and sensors to the control level by means of an economical point-to-point connection.

The new communications standard IO-Link below the fieldbus level allows central fault diagnosis and location as far as the actuator/sensor level and simplifies both commissioning and maintenance by allowing the parameter data to be modified dynamically, direct from the application.

Improvements in the intelligence of field devices and their integration in the overall automation support data access down to the lowest field level. The result: greater plant availability and reduced engineering overhead.

As an open interface, the IO-Link can be integrated into all common fieldbus and automation systems. Consistent interoperability ensures maximum protection of investment. This also applies in the context of existing machine concepts for continued use of sensors without an IO-Link interface.

Together for integrated quality

The requirements for integrated communication are increasing. At the same time, the variety of field devices, actuators, and sensors is increasing immensely – with ever greater intelligence.

IO-Link offers the solution for these requirements and is seen by manufacturers as a valuable addition to the communications landscape (including AS-Interface).

As a committed driver of this issue, Siemens is further developing not only its product and system range accordingly, but by integrating IO-Link in Totally Integrated Automation, it is also providing a unique integrated communication solution.
