4X Registers V4 (M550/M560)

The registers are listed with their Modbus addresses.
The data held at these addresses are Read-Only, Write-Only or Read+Write as indicated below.
4X registers are read using function 03h and written using function 10h.
A sample write packet will look like this:-
[Node][10][start address][No. of Double Registers][Data length in bytes][CRC(2 bytes)]

e.g. To set Node 23h System Voltage and System Current together:-
[23h][10h][0000h][0004h(4, 2 byte regs)][08h(2, 4 byte regs)][CRC(2 bytes)]
