%MW0.0 = Modbus address 0 (dec)
%MW0.1 = Modbus address 1 (dec)
%MW0.2 = Modbus address 2 (dec)
%MW0.3 = Modbus address 3 (dec)
...
%MW0.32767 = Modbus address 32767 (dec)
%MW1.0 = Modbus address 32768 (dec)
%MW1.1 = Modbus address 32769 (dec) ...
Please read help in ControlBuilder, type Modbus addresses
