5.2.4 Offset for indicating the real level in the tank
The zone between tank bottom and lower edge of the probe can be entered as
offset value [OFS]. So display and switch points refer to the actual level (point of
reference = tank bottom).
For [OFS] = [0]: The reference point is the lower edge of the measuring
probe.
The set offset only refers to the display on the unit. It has no effect on the
process value transmitted via IO-Link. The OFS parameter, however, is
correctly transmitted via IO-Link and can therefore be taken into account.

5.2.5 Defined state in case of a fault
In case of a fault, a state can be defined for each output. If a fault is detected or if
the signal quality is below a minimum value, the outputs pass into a defined state.
For this case the response of the outputs can be set via the parameters [FOU1],
[FOU2] (→ 10.3.7) .
5.2.6 IO-Link function
This unit has an IO-Link communication interface which enables direct access to
process and diagnostic data.
In addition it is possible to set the parameters of the unit while it is in operation.
Operation of the unit via an IO-Link interface requires an IO-Link capable module
(IO-Link master).
