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 Beckhoff EL6224/EJ6224 IO-Link Master Terminal has four IO-Link ports. One IO-Link device can be connected to each of them. IO-Link is therefore not a fieldbus, but a point-to-point connection (see following figure).

CAUTION

Damage to the devices possible!

The IO-Link Devices must be powered from the 24 V supply of the EL6224/EJ6224, otherwise the IO-Link port may be damaged!
