Color coding
The sockets for ET-Connection and the power supply of the modules are color-coded. These
colors correspond to the colors of the offered cables.
Pin assignment of the IO-Link sockets
Note
Port Class B
The pin assignment of the IO-Link interface corresponds to the IO-Link specification as per
Port Class B. Port Class B is specially suited for the connection of actuators with additional
supply (e.g. valve terminals).
To connect devices with Port Class A (e.g. sensors) to the communication module
CM 4xIO-Link 4xM12, a 3-wire connection cable should be used (Port Class A compatibility).
The table below shows the pin assignments of the 4 sockets for the connection of IO-Link.

* If you use the sockets for IO-Link as Port Class A, you may
not place any signals on pins 2 and 5.
The M12 connectors are designed according to IO-Link specification as port type Class B.
Pins 2 and 5 contain an additional power supply.
Reaction-free connection of devices with different port types (Class A and Class B) is
possible using a 3-wire connecting cable (assignment of pins 1, 3 and 4).
