IO-Link master principles

3.1

Topology

The IO-Link master serves as a gateway between an automation system (EtherCAT) and the IO-Link
devices. It has several IO-Link ports, to each of which an IO-Link device can be connected.

Ports

Two classes of IO-Link ports are defined in the IO-Link specification:

Class A ports

Class A ports are intended for the connection of IO-Link devices of the type sensor.

Contacts of a class A port:

• Supply voltage for the IO-Link device: L+, L-

• Data cable for serial communication or switching signals: C/Q

• Data cable for switching signals (optional): DI/DQ

Class B ports

Class B ports are intended for the connection of IO-Link devices of the type actuator.

Contacts of a class B port:

• Two electrically isolated supply voltages for the IO-Link device:

◦ Sensor/logic supply: L+, L-

◦ Actuator supply: P24, N24

• Data cable for serial communication or switching signals: C/Q
