OPERATION
8.2.2
Exprt mode
The Exprt mode offers the full functionality of the display.
Advanced functions are available for:
−
Switching outputs
•
Output: Process variable, hysteresis/window, polarity, simulation, electrical
property (NPN / PNP / DRV (push-pull))
•
Using the switching output as input for initiating actions (minLvl, maxLvl, etc.)
−
Analog outputs
•
Switching the process variable, 4–20 mA/0–10 V, error signal, simulation
−
Configuration
•
Display, units, offset, lock
−
Measurement
•
Detailed signal quality, filter, TrsHld
Note:
Exprt mode is automatically activated when IO-Link is used.

If the level is fluctuating around the set
value (e.g., ripple movement during fill
-
ing), the hysteresis keeps the switching
status of the outputs stable. When the
level is increasing, the output switches
when the respective switching point
(SP) is reached; if the level sinks again,
the output switches back only after the
reset switching point (RP) has been
reached.
