To accomplish mapping, the BAS Remote Master module is loaded (via FTP) with a
user-generated CSV file (bas_cfg.csv) that specifies the following:
Modbus Device Address (ID) BACnet Instance
Modbus Variable Number BACnet Object Type
Modbus Variable Type (Register or Coil) BACnet Object Name
The Modbus register types are the following:
16-bit signed 32-bit signed
16-bit unsigned 32-bit unsigned
32-bit float
The 32-bit values are constructed from two consecutive 16-bit registers that have their
high and low words defined.

spreadsheets have been developed to provide you with a means of
loading Modbus device profiles into the BAS Remote. You can access these files at …
www.ccontrols.com/basautomation/m2bsoft/
… where you will find the Project Builder file and various Modbus Device Profiles for
downloading to any convenient location on your local hard drive. You will use these
files to build a Project that will contain the Modbus Device Profiles you choose to install.
The first step in the process is to download:
M2B_ProjectBuilder_A1.xls
When you save and open the above file, the following Excel worksheet appears:
Figure 46
— Project Builder Worksheet (Excel)
As the above sheet loads, the Project Name is checked. If none is found, a dialog
appears and prompts you to enter a Project Name which will then appear in the upper
left portion of the sheet. Because this will also be the name of the Project file that will
be saved with an XLS extension in a new directory of the same name, you must only
use characters that are allowed in Windows filenames. After the Project Name has
been accepted (this may take several seconds), you may work with the Project Builder.
Double clicking a column header (just below the blue row) will display information about
that column. (
Red column headers identify columns that you can edit.)
The next step in building a project is to add one or more Modbus Device Profile(s) to the
Project Builder. If you have a valid Internet connection, clicking the Contemporary
Controls logo in the top row of the worksheet will take you to the same web page from
