The product comes with the IO-Link communication interface.
IO-Link communication is a master-device communication system.
The product can be operated in standard I/O mode (SIO) or IO-Link mode (IOL). All
automation functions and other parameter settings are effective in IO-Link mode and in
standard I/O mode.
The following functions are supported via the standard IO-Link communication inter‐
face:
•
Flexible sensor settings
•
Digital transmission of sensor signals to the IO-Link Master
•
Visualization and configuration of the sensor
•
Diagnostics /condition monitoring
•
Device identification
•
Easy device replacement
•
