Holding Register of Modbus RTU module. The 6 Data Type
options are “16-bit Signed Integer”, “16-bit Unsigned Integer”,
“16-bit Hex”, “32-bit Signed Long”, “32-bit Unsigned Long”,
and “32-bit Floating Point”. If the “16-bit HEX” option is
selected, it is required to setup the corresponding scale
parameters for linear transformation from HEX value to real
value. The PMC/PMD will retrieve the HEX value and transfer
it to real value in floating point format, this real value could be
included in the IF-THEN-ELSE rule for edition.
If users select “32-bit Signed Long”, “32-bit Unsigned Long”,
or “32-bit Floating Point”, the option “Inverse(Big Endian)”
will appear. Enable “Inverse(Big Endian)” to receive the data in
big endian format correctly.
After finishing the “Start Address”, “Data Number”, and “Type”
setting; click on “Add” button. A new Holding Register address
block will be added to the Modbus address mapping table. All
added address blocks will be located in sequences staring from
the Starting Address (The address number on the first column of
the “Local Address” indicates the local Modbus address of
PMC/PMD to keep the Holding Register data.).
Figure 7-50 shows an example about Holding Register setting
for a Modbus RTU module. The starting Modbus address of the
Holding Register block is 40060(40000 + 60), it requires to set
2 continuous Holding Register data in the setting, and the data
type is “32-bit Floating Point”. So that these retrieved Holding
Register data will be kept in PMC/PMD Address 40300 and
40302.
