Chapter 6 Applied Instruction 5. SR209 and SR212: The setting values of the communication protocols are shown in the following table. 6. The example of the communication format: The communication format: Baud rate 9600 7, N, 2 After checking the table, users can get the communication format 16#0028. Write 16#0028 into SR209. SM210/SM212 ： The choice between the ASCII mode and the RTU mode ON: The RTU mode OFF: The ASCII mode Take the standard Modbus format for example. 6-386 b0 Data length 7 (value=0) 8 (value=1) Parity bits 00 : None b1 01 : Odd parity bits b2 10 : Even parity bits b3 Stop bit 1 bit (value=0) 2 bits (value=1) b4 0001 (16#1) : 4800 b5 0010 (16#2) : 9600 b6 b7 0011 (16#3) :
