Function monitoring
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 cable break,
both outputs are de-energized. This means that function monitoring is possible in addition to
level monitoring. The behavior of the switch outputs can be configured via IO-Link.
