Modbus protocol in the register 1 (0x00) and 2 (0x01).

See Application Note Modbus AN0103 (available at www.epluse.com/ee431).

The measured values are saved as 32-bit float values (FLOAT32) and 16-bit signed integers (INT16). The factory setting for the Modbus address is 66 as an INT16 value. This address can be changed by the user in the register 1 (0x00), permitted values are 1…247.
The serial number as ASCII-code is located in read-only registers 1 – 8 (0x00 – 0x07, 16 bits per register).
The firmware version is located in register 9 (0x08) (bit 15…8 = major release; bit 7…0 = minor release). The sensor name ASCII-code is located in read-only registers 10 – 17 (0x09 – 0x11, 16 bits per register).

NOTICE
When reading the serial number or the sensor name, it is always necessary to read all 8 registers, even if the desired information requires less.

NOTICE
To obtain the correct floating point values, both registers have to be read within the same reading cycle. The measured value can change between two Modbus requests, exponent and mantissa may get inconsistent then.
