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.
Connection examples
The following figure shows a connection example using an S7-1500 IO-Link master with IP20
degree of protection.
