21.5 Create a Custom Modbus Map
Creating a custom Modbus map is not complex. Custom maps allow the user to place the data into
sequential registers and use block read commands in the DCS program. A custom map also allows
the user to exactly replicate the map of an existing system you are going to replace with a VC-8000.
Follow these steps to create a custom Modbus Map.
1. Finish your MPS configuration and Export the Standard Map
Your MPS configuration will need to be completed before you export the map. Start with the standard
map. Open (or upload) your MPS configuration and select File, Export Modbus Map.
2. Modify the Standard Map in Excel
Open the file in Microsoft Excel. Delete unwanted rows (only
rows). Do not change the order of columns or the column
headers. Do not delete columns.
Change the register and bit addresses as needed. Remember
that the VC-8000 register addresses use 6 digits; so, register
30001 will be written as 300001.
Save the file as a CSV (Comma delimited) file.
COMMON MISTAKE
VC-8000 register addresses are written using 6 digits. Register 30001 will be written as
300001. Or in other words function (3) register (00001).
3. Import the .CSV file into the configuration file
First, open (or upload) your MPS configuration file. Then import
the new Modbus map (File, Import) into the configuration file.
The custom map is now integrated into your computer
(software) – but is not yet in VC-8000.
If there are no errors, the software will display “Modbus Map
imported successfully”. If there are errors, the dialog will show
the spreadsheet rows that contain the errors.
4. SEND the new configuration file to the rack.
You must SEND the configuration to update the rack with the new Modbus map.
COMMON MISTAKE
The Modbus map is part of the rack configuration file. You must SEND the configuration file to
the rack after you import the map.
21.5.1 Reverting Back to the Standard Map
If you decide not to use the custom Modbus Map (or you just want to start over) you can revert to the
original standard map:
• Open (or GET) the current rack configuration file.
• Select File, then select Revert to Standard Modbus Map.
• SEND the configuration file (with the revised map) to the rack.
