Diagnostic
information

To increase measuring accuracy, predefined compensation values can be used for the compensation of the
speed of sound and acoustic density specifically for your application. The compensation values can be read
into the device from external measuring devices via Modbus TCP or entered as constant measured values
(Configuration of compensation value 1…4). The compensation values are only available if they were
provided in the data record of the concentration app upon delivery.
Compensation value 1
Read /

IEEE754 32 bit 0x1852:0x1853 2
Floating point
number in IEEE754
format (big endian)
Compensation value 2 Read /

Compensation value 3 Read /

Configuration of
compensation value 1 Read /

16 bit unsigned 0x1D6B 1
• 0 = disabled:
measured
variable is not
taken into
consideration.
• 1 = fixed value:
entered
measured value
is taken into
consideration.
• 2 = Modbus: the
measured value
received via
Modbus TCP is
taken into
consideration.
Configuration of
compensation value 2 Read /
write 16 bit unsigned 0x1D86 1
Configuration of
compensation value 3 Read /
write 16 bit unsigned 0x1DA1 1
Configuration of
compensation value 4 Read /
write 16 bit unsigned 0x1DBC 1
While values are transmitted in "big endian" format during Modbus communication, in
line with specifications, the sequence of the bytes received may have to be reversed,
depending on the system used, to convert between big endian and little endian
format.
Example: read concentration A
The result is a floating point number in the format IEEE754 32 bit. The value is saved in
two consecutive addresses, with the first address containing the least significant word
