IO-Link system layout

An IO-Link system consists of an IO-Link master and one or more IO-Link devices, i.e. sensors or actuators. The IO-Link master provides the interface to the higher-level controller and controls communication with the connected IO-Link devices.
The IO-Link masters from Beckhoff have several IO-Link ports, to each of which one IO-Link device can be connected. IO-Link is therefore not a fieldbus, but a point-to-point connection.

CAUTION

Risk of device damage!

The IO-Link devices must be powered from the 24 V power supply of the IO-Link master provided for this purpose, otherwise the IO-Link port may be damaged!
