RS485 bus topology

2017-02-19

RS485 bus is an economical and practical industrial bus mode for equipment networking. In some complex network applications, the communication quality of RS485 bus needs to be tested and debugged according to the construction experience. Therefore, although 485 bus is simple, the network application must be carried out in strict accordance with the construction specifications, and different actual environments should be considered Different bus topologies, this paper introduces three common bus topologies. 1、 Daisy chain topology of RS485 bus topology daisy chain topology is the standard and specification of RS485 bus wiring, is TIA and other organizations

Application of RS485 interface chip in industrial control field

2017-02-19

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

2016-10-12

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

What is SAR ADC

2016-10-12

SARADC is also often referred to as binary search ADC, which is mainly used in medium and high resolution and medium and high conversion rates. Its working principle is based on a binary algorithm search method. By sampling the input signal, the sampled value is sequentially compared with the reference voltage value generated by the D/A network, and finally the logic output from the highest to the lowest is obtained. The basic structure is shown in Figure 1: It mainly includes sample-and-hold circuit (S/H), comparator, D/A conversion network and SAR logic control circuit. Figure 1 Schematic diagram of the SARADC structure 　　 after the analog input signal is sampled and held (VIN),
