dot should be placed artificially Ex.: Reading
the value 257 should be treated as 25.7%
2. The value 0x8000 means, the parameter is
not available.
Alarms register bit alignment
Read and write
Alarms register are 32-bit wide
Desired values: read/write
Device operating state
Sensed values
1. The sensed values have 1/10 precision.
After reading the sensed value it should be
divided by 10.
Ex: Reading the number 257 should be
treated as 25.7
2. Reading the value 0xFFFF means that ,
the parameter does not exist
