5.3.5.4 Configuration of sensors with look-up table
A look-up table can be stored for sensors with a special signal characteristic curve. See also section
5.3.6.5 "Creating new sensors".
In the look-up table, markers of the signal
characteristic curve can be entered be-
tween which linear interpolation is per-
formed. The order in which the sampling
points are entered is arbitrary. If the win-
dow is closed via the "OK" button (green
token), the table is automatically sorted
and saved.
Note: If you want to delete a marker,
simply double-click on the number field
(1-15) of the respective line.

5.3.5.5 Creating new sensors
If you use sensors that are not included in the predefined sensors, you can create your own new sen-
sors. New sensors can be defined for:
Serial
• SDI-12
•
Modbus RTU
• Modbus TCP
• NMEA
A list of supported NMEA da-
tasets can be found in chapter
13.1.
Digital and status
• Status
•
Impulse
• Frequency
As switch (relay, reed), open
collector (OC) or logic signal
(0/1) from 0...30V
Analogue signals
• 5 V bipolar,
•
5 V unipolar,
• 50 mV bipolar,
• 0/4…20 mA,
•
500 Ohm and
•
5000 Ohm.
To create new sensors, first close the configuration window.
Click on the "Define sensors" button in the main selection to open the "Define sensors" window.
Important note: Be careful when configuring new sensors. Due to the approach of ensuring
the greatest possible flexibility in configuration, it is also possible to create "nonsensical" sensor config-
urations that could interfere with the operation of the Ser[LOG]. It is therefore recommended to work
with the predefined sensors if possible or to derive new sensors from existing sensors!
