The following is a list of all the measurement registers that can be read through modbus. All data is
expressed in floating point and uses 2 registers for 4 bytes in total. The data is available from registers
2..110 and 1002..1110. The values in both ranges are the same, but the order of the registers is
switched.
- Big-Endian (High-Byte vor Low-Byte) - Register 2…110
- Little-Endian (Low-Byte vor High-Byte) - Register 1002...1110
Modbus supports the commands “Read Holding Registers” (0x03) and “Read Input Registers” (0x04).
Registers 2..110 are addressed as 1..109. Only requests with a odd register address and a quantity of
registers that is a multiple of 2 are valid. Other request will return an “Illegal Data Address” (0x02)
exception code.
