6.3.3 Topology IO-Link
The SREH-50-IOL is a port class B IO-Link device. This means it needs 2
separate power supplies: One for the logic and one for the motor.
The use of an IO-Link master of port class B is recommended. Such masters
have two galvanically separated voltage inputs.
The connection between the PLC and IO-Link is made via a field bus.
The following figure shows an example with an 8-port master, where 2 ports are
used for SREH-50 IOL modules.

Alternatively, a master of port class A can also be used. With port class A, only
one supply is available. Therefore, in this case, the motor voltage must be fed
in via a Y-cable.
