Annex // nanoFlu
Read / Write multiple registers (0x03 / 0x10)
The following values are in the registers:
Designation R/W Address Data type Description
Modbus slave ID RW 0 Uint16
Modbus server address of the nanoFlu.
Allowed addresses: 1…247
Measurement timeout R 1 Uint16
The time in [10-1 s] that the currently running
measurement process will still require (see
also “Trigger measurement”)
Device serial number R 10 Char[20] Serial number of the nanoFlu sensor.
Firmware version R 20 Char[10] Version number of the installed firmware.
Self-trigger activated RW 100 Bool
Indicates whether the sensor is in automatic
mode (only necessary for first installation).
Self-trigger interval RW 101 Uint32
The measurement interval in [s] for the auto -
matic mode. Adjustable range: 1s – 86400s.
Moving average RW 103 Uint16
Number of individual measurements which are
averaged for a measurement.
Adjustable range: 1 – 25.
System date and time RW 104 Uint32
Date and time as seconds since 1 January
1998. Starts again after each power-up!
Device description RW 106 Char[64]
An unrestricted description of the sensor e.g.:
“south supply line”.
Parameter Index for offset
/ scaling
RW 400 Uint16
When setting the parameter index, an offset
or scaling factor can be set for the selected
parameter.
Parameter index of nanoFlu for each parame-
ter: 0x0000.
Activate Offset/Scaling RW 401 bool Specifies whether offset and scaling are used.
Offset RW 402 Float
Parameter offset. Formula: scaled = (calibrat -
ed – offset) * scaling
Scaling RW 404 Float
Scaling factor. Formula: scaled = (calibrated –
offset) * scaling
Available substances R 500 Uint16
Available parameters:
1 := chl-a 4 := CDOM 2 := blue
Before the registers can be read above address 1000, a measurement must be triggered.
