S
with SDI-12 interface
䡵
Create a OTT netDL/OTT DuoSens channel with “SDI-12 Master” or
“OTT SDI RS485” function block (“Serial sensors” tab).
䡵
Make the following settings:
䊳
Terminal block
OTT netDL “SDI-12 Master”: C 3-4 (specified)
OTT netDL “OTT SDI RS485”: C 1-2 (specified)
OTT DuoSens “SDI-12 Master”: A 3-4 (specified)
OTT DuoSens “OTT SDI RS485”: A 1-2 (specified)

Slave address
SDI-12 bus address. Each slave address may be
assigned on an SDI-12 bus line only once. (Check/
set: refer to OTT netDL/OTT DuoSens Operating
Instructions, Chapter SDI-12 Transparent Mode.)
Typical setting: “0” (only one OTT Pluvio

identifies which value (the xth of n status
information) of the OTT Pluvio

channel. Typical setting: “1” (first one of nine (“M!”
Measuring Mode) or three (“M1!” Measuring Mode)
measured values)

Measuring mode
“M!” or “M1!” (for allocating the measured values,
refer Chapter 6, “SDI-12 commands and responses”)

measured values, refer to Chapter 6, “SDI-12 com-

䊳
Concurrent mode
only for OTT netDL: refer to the operating program
online help.
䊳
Instantaneous value
only for OTT netDL: refer to the operating program
online help.
䡵
In the respective Channel function blocks, set the required units and number of
digits after the decimal place
Notes:
䊳
For recording all the 12 measured status information for an
OTT Pluvio
2
S, 12 channels in the OTT netDL/OTT DuoSens are thus necessary.
The first channel contains the function block “SDI-12 Master” or “OTT SDI RS485”
as the input signal. The other channels each contain a function block “Virtual
Sensor” (V02 to V09) as the input signal, (V03 in case of M1!). Of course, just
individual channels can also be recorded. In this case, there are fewer entries
required in the “Value no./Virtual Terminal ID” field.
䊳
Further information on the SDI-12 commands and responses used can be found
in Chapter 6, “SDI-12 commands and responses”.

The OTT Pluvio
2
S makes the measurement results available for retrieval
immediately after the

and
aM1!
SDI-12 commands.
