Application of RS485 interface chip in industrial control field
The RS485 interface has good anti-noise interference, long transmission distance and multi-station capability, making it the preferred serial interface, and RS485 can carry multiple loads, and a PC can be realized by slightly modifying the program. The machine monitors multiple lower-level computers. In the daily measurement verification, the inspectors can access a large number of instruments and meters, most of which are equipped with RS485 communication ports. RS485 has become the network communication interface of various industrial equipment due to its cost advantage and easy implementation. It plays an important role in industrial control.

RS485 communication port protection scheme
RS485 communication interface chips are widely used in various smart meters. Smart meters with RS485 interface can not only achieve point-to-point communication, but also achieve networking functions. RS485 provides the most reliable meter reading method for remote meter reading. The RS485 interface chip is widely used, and the application environment is different. The field environment such as smart meters and industrial control is often very harsh. The RS485 communication port needs to be protected from static electricity, lightning surge protection, and 380V mains access protection. In order to avoid damage to the smart instrument and industrial control host. This article introduces several typical RS4
