Register Map Profile
7.1
Introduction
This chapter describes about Modbus Register Map table and profile.
To have better view on all of parameters of VP-1405A you must
consider bellow items to communicating and translating data of
registers.
o
In this section all of references to the hexadecimal register
number, byte number, word number and bit numbers all start
from “Zero”.
7.2
Summary of Data Conversion
The raw value of each memory register based on the unit value and
data format and scale factor can be analyzed by master. For
example, the calculation factor of the voltage register is 0.01. When
the value read by the user via raw value of corresponding register as
example like 5312, the Battery Voltage will be: 5312 × 0.01 = 53.12
Volt.
It is called also Engineering Value conversion. In this section we
listed summary for most common use of power parameters in
VR-1405A. For the bellow table also review the bellow terms:
RAW
: RAW shows the raw value read from VR-1405A via
corresponding register value.
7.3
Memory Map Data Format
Data format of each memory register value of VP-1405A based on its
meaning is difference with other one. In the last column memory
register map table in bellow of this section there is a column named
as “FORMAT”.
Each format type is described in memory map data format table as
bellow.
