As a remote network communication control method with advanced technology, high reliability, complete functions and reasonable cost, CAN-bus has been widely used in various automation control systems. For example, CAN-bus has incomparable advantages in various fields such as automotive electronics, automatic control, smart buildings, power systems, and security monitoring.
Scope of application: Various automatic control networks, such as building automation, automatic instrument control, remote data transmission, motor control, etc. can achieve long-distance transmission (≤ 10KM), adjustable working rate (1Mbps≥ communication rate ≥ 5Kbps) to upgrade the original RS-485 network 2-wire communication.
Circuit features: Can be directly interfaced with the widely used C51 series microcontrollers, the circuit is simple and easy to use; DC-DC module and photoelectric isolation device are used to suppress electromagnetic interference and protect the system circuit from being affected by the network; 2-wire communication, each bus The node needs to provide its own power supply; adjust the value of the slope resistor R33 according to the communication speed, generally between 16K and 140K.

The role of DeviceNet terminal resistor
DeviceNet_network is a fieldbus network protocol based on Controller Area Network (CAN). In the DeviceNet network, the terminal resistor plays the role of compensation and protection for signal transmission. The function of the terminal resistor is to eliminate signal reflection and interference and ensure the signal transmission quality.
