In Memory Register map table in bellow of this chapter there are
some columns which describe about register profile as bellow:
 GROUP: This column shows the meaning of group of
register. You may have some register together to show a
data like time or other structured data.
 REG ADDR (HEX): This column shows Register Address in
format of hexadecimal number. Each Address in table
represent address pointer to one register (word value) of
Modbus. For values in 32 bits format two register addresses
are allocated.
 DESCRIPTION: This column consists of full description of
each register address and map. In some case in table you
may find the one merged row that describe about following
register functions such as READ or READ/WRITE or
describe about kind of register as holding or set-point and
etc.
 REGISTER VALUE RANGE: This column shows about the
valid range of register. This is useful data for reading and
analyzing read register value or to be used to check valid
range for set-points. The format and range of value is
described for each register separately.
 UNIT VALUE: This column shows about each count of RAW
value read or set from or to register address means about
which unit value. This column must be in purpose of other
columns of SCALE FACTOR and FORMAT.
 SCALE FACTOR: This column shows scaling factor for
each count of RAW value read or set from or to register
address. Each count of RAW value of register must be
multiply by SCALE FACTOR. The meaning of SCALE
FACTOR of each register is described separately and if this
column shows none or dashed means that there is no
scaling factor.
 FORMAT: This column shows format type of RAW value of
each register value. There are a lot of format types that has
been coded in other table. Each register value based on its
format type must be analyzed for reading or writing. For
example the format type of "F1" represent that the register
raw value must be typed cast to the "16 bit unsigned integer
numerical value" and format type of "F2" represent that the
register raw value must be typed cast to the "16 bit signed
integer numerical value".
