RS485 communication
Siemens S7-300/400 (PC Adapter) driver protocol
1. If you use adapter to communicate, PLC must be 187.5K.
2. HMI communication setting: 19200, 8, 2, odd; station No.: 2
3. If we use PC adapter, PLC station No. is not necessary, so the communication is one-to-one.
4. You must set DB first, or register can not write(DB.DBX, DB.DBW, DB.DBD). The initial address
of DBm.DBW and DBm.DBD must be even.
