IO-Link

The IO-Link communication system is used for the exchange of serial data from decentralised devices on the field
level. The connection type corresponds with a point-to-point connection, which means it can be connected to only
one device at every IO-Link interface.
The IO-Link interfaces (ports) can be operated in the following operating modes:
– Inactive (for unused ports)
– DI (the port acts like a digital input)
– IO-Link (IO-Link communication takes place at the port)
The module described in this document has IO-Link interfaces (ports) of Class B (Type B) that provides an
additional load voltage supply.
The devices description by IODD (IO Device Description) is not supported.
