Modbus function code 04: Read Input Registers
The data format used is IEEE 754 single-precision binary floating-point format: binary32
Parameters are represented as two consecutive Modbus registers.
The value of a parameter is represented in SI unit as secondary values on transducer input.
To calculate primary values, use the primary to secondary transformer ratio of parameter CTR, PTR
The CTR and PTR parameter can be configured by the user by editing primary to secondary
current- and voltage-ratio in ConfigLQT.
