Function monitoring
In the order configuration: With two-channel evaluation, functional monitoring of the sensor is also
possible in addition to level monitoring, provided that no other monitoring option has been
configured via IO-Link.
When both outputs are connected, the MIN and MAX outputs assume opposite states (XOR) when
the device is operating fault-free. In the event of an alarm condition or a line break, both outputs are
de-energized.
