Included in the table are all register addresses that can be read over Modbus. All data are offered in
data type: float with 2 registers and a total of 4 bytes.
The data are located in registers 2 to 110 and 1002 to 1110. The data in the Modbus registers can be
retrieved in the format:
- Big endian (high byte before low byte) - Register 2 to 110
- Little endian (low byte before high byte) - Register 1002 to 1110.
The Modbus functions “Read Holding Registers” (0x03) and “Read Input Registers” (0x04) are
supported. Register 2 to 110 (1002 to 1110) are addressed as 1 to 109 (1001 to 1119).
An example: if the register for the counter status active power of phase L3 is to be read out, register 7
is input for big endian byte order and 1007 for little endian.
