MODBUS REGISTER ADDRESSING
This table lists the addressed assigned to each data point. Registers are read MostSignificant Byte (MSB) first. 32 bit floating point values are encoded per IEEE Standard 754.
For floating point format variables, each data point appears twice because two 16-bit addresses are required to hold a 32-bit float value. The 16 bit Most Significant Word
(MSW) is in the lower address of the register pair, while the least Significant Word (LSW) is in the upper address.
Modbus RTU function codes supported: 3=read holding registers; 6=preset single register; 17=report Slave I.D.
