COMPONENTS OF AN IO-LINK SYSTEM IO-Link is a standardised, bi-directional communication protocol supported on
sensors or actuators. It is not another fieldbus, but instead was developed to be as simple and universal as possible. An IO-Link system consists of the following components: • IO-Link devices: Intelligent sensors and actuators that communicate via the IOLink protocol, and can send and receive detailed information about their status, performance and environment. • IO-Link Master: The heart of an IO-Link system, it is a central device that acts as a gateway between the IO-Link devices and the upper-level control system — such as a PLC or DCS — and coordinates
