IO-Link
The sensor can be used in standard I/O mode (SIO) or IO-Link mode (IOL). All auto‐
mation functions and other parameter settings are effective in IO-Link mode and in
standard I/O mode. Output of binary switching signals in standard I/O mode via pin
4 / black wire and via pin 2 / white wire.
Information on the IO-Link functions (IODD) can be found in the enclosed IO-Link
