3.1

Hardware configuration

Basic configuration with IO-Link I/O modules
Connect the IO-Link I/O module to an IO-Link port of the master with an M12-A coded plug.
The maximum cable length between an IO-Link device and an IO-Link master is 20 m.
Power is supplied to the IO-Link I/O modules via the IO-Link master.
You can connect one IO-Link I/O module per IO-Link port to an IO-Link master.
For I/O modules with high power demand, an M12-L power connector is available for an
additional supply voltage.
You can find information on the maximum infeed current in the technical specifications of
the modules in the respective equipment manuals or on the Internet
(https://support.industry.siemens.com/cs/ww/en/view/109742667).
3.2

Configuration of IO-Link I/O modules

Each ET 200AL IO-Link I/O module has an M12 A-coded plug for connection to an IO-Link
master.
When connecting the IO-Link I/O modules to an IP65/67 IO-Link master, pay attention to the
required port class (Type A or Type B). You can find the technical specifications in the
respective equipment manuals or on the Internet.
PROFINET IO
The figure shows an IO-Link configuration in combination with a PROFINET IO network. The
line topology of PROFINET IO is supplemented with a star topology of IO-Link.
Note
Configuration variants
The IO-Link I/O modules can also be operated on an IO-Link master in other networks.
