· Modbus protocol:Modbus is a data link layer protocol that defines how data is transferred between two devices.It can run on many physical layers such as RS485, Ethernet and so on. ② Communication mode · RS485 protocol:RS485 supports half-duplex and full-duplex communication, and the da...
The system only needs to detect the potential difference between the two lines can be. But people often ignore the transceiver has a common mode voltage range, RS-485 transceiver common mode voltage range of -7 to +12V, only to meet the above conditions, the entire network can work ...
