Figure 6-40 shows an example about Input Register setting for a
Modbus RTU module. The starting Modbus address of the Input
Register block is 30010(
30000
+ 10), it requires to set 3 continuous
Input Register data in the setting, and the data type is “32-bit
Floating Point”. So that the WISE can access the
3
0010,
3
0012 and
3
0014 Input Register address of the module, and these retrieved
Input Register data will be kept in WISE Modbus Address
3
4500
、
3
4502 and
3
4504.

Input Register Setting Example for Modbus RTU module
To modify the starting address or quantity setting, please click on
the setting block to perform the modification. The user could also
modify Type, Scale Ratio and Offset on this interface. The Scale
Ratio setting and Offset setting allows to transform the Input
Register value in this block by linear transformation. The formula is
as follow:
Transformed Value = Scale Ratio x Input Register value + Offset
After the linear transformation, the Transformed Value will be saved
in floating point format on the WISE (no matter what format the raw
Input Register value was in the device). The default Scale Ratio will
be 1 and the default Offset is 0, indicating not using linear
transformation.
