Functions
IO-Link is a point-to-point connection between a master and a device. Both conventional and
intelligent sensors/actuators can be used as devices at the IO-Link via unshielded standard
cables using proven 3-wire technology. IO-Link is backward compatible with conventional
digital sensors and actuators. The circuit state and data channel are designed in proven
24 VDC technology.
For additional information about the SIMATIC IO-Link technology, refer to the "IO-Link
system Function Manual" on the Siemens Industry Online Support website
