9.2 MODBUS communication protocol
The terminal support MODBUS RTU multi-drop protocol. In MODBUS RTU network the
terminal act as slave node and the registers can be accessed by reading hold register 03 command
or writing hold register 06 command.
Set F3.1=3 and F3.6 as any address from 1~99 (user is responsible to ensure the node
address is unique in the network else will cause the network down).
In modbus register the weight displayed as 16-bit signed int from -32768 ~ +32767. The
decimal point information is stored in a specified register, the PLC programmer should read the
decimal point correctly to place point on the reading weight data.
Below registers are read-only registers by 03 function code
Formula No. :0001~1010 =1~10;
Weight division:
0000=0.001 0001=0.002 0010=0.005 0011=0.01
0100=0.02 0101=0.05 0110=0.1 0111=0.2
1000=0.5 1001=1 1010=2 1011=5
1100=10 1101=20 1110=50 1111：no
