Reading Parameter data through User Assignable Registers:
In assigning query Voltage and Power Factor parameters were assigned to 0x 200 and
0x201(Table10) which will point to user assignable 3xregisters 0x200 and 0x202 (table9).
So to read Voltage and PowerFactor data reading query should be as below.
