It is also possible to configure SP1 as the lower switch point and SP2 as the upper switch point.
The lower switch point must be at least 10% lower than the higher switch point.
4.4 IO-Link mode
IO-Link allows the configuration of internal parameters such as switching threshold, start-up delay and
switching behaviour (normally closed/normally open) as well as reading the current measured values.
Furthermore IO-Link protects against signal faults and measured value losses as well as tampering
with the sensor. IO-Link facilitates the identification of connected devices in the system and provides
diagnostic functions.
