number on the first column of the “Local Address” indicates the
local Modbus address of PMC/PMD to keep the Input Register
data.).
Figure 7-48 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 these retrieved Input Register
