CAN IS A SERIAL BUS CONTROL PROTOCOL that features high flexibility and integration capabilities. Allowing workstations to be added to existing networks without needing to modify or adjust the hardware or software, it also provides high-level security and efficient control in real-time. In the past, an RS-485 interface relied completely on the software mechanism. The determination of packet accuracy and prevention of packet collision was performed by the software program. In contrast, the CAN hardware features automatic error detection and priority determination. The security of network packets is checked by the hardware, which can complete multiple error checking operations in a very short time. Consequently, the transmission of a large number of network messages is more reliable and more efficient.
Multi-master support
A highly varied selection of CAN controllers, software and modules create solutions for a variety of application needs.
To keep pace with the ever-increasing sophistication of industrial technology and the pervasiveness of industrial automation, major equipment manufacturers and system integrators alike have adopted the CAN Bus as their core communication system. In the industrial sector, the CAN Bus is generally regarded as an integral component to the stability and security of any system. In real industrial settings, a wide range of communications interfaces, including RS-232, RS-485, Ethernet, and CAN Bus, to name a few, are used by the majority of automation applications. To create a heterogeneous system, it is necessary to take into consideration the various interfaces, together with their distances from the Master device and the speed at which they operate, SOURCE: ICP DAS
The CAN Bus supports multi-master operation, making it the most efficient serial bus. Any device on the CAN network can actively send packets at any time. Such as the heartbeat packets from the device, real-time alarm packets, or other information. This feature makes it more outstanding than other serial buses. CAN Bus utilization rate is very high, reducing unnecessary polling and removing the need to waste time waiting for acknowledgment packets, thereby speeding up the transmission of information and decreasing communication energy. The CAN Bus is a serial communication bus system. That has high-level data integration capabilities, even in harsh environments that have extensive electrical noise interference. It also provides high fault tolerance and error correction abilities. The Bus itself features multi-master electrical characteristics, and its open architecture creates flexibility.

meaning that the combined communication performance and cost is difficult to estimate. To complicate matters further, integration issues and stability concerns are both very real and common. To resolve these difficulties, numerous types of converter and gateway devices are available on the market including those made by ICP DAS. From its many years of experience, ICP DAS has produced hundreds of high-quality CAN Bus products. The CAN Bus converter can manage a range of transmission interfaces, meaning that more complex network structures are within easy reach. The ICP DAS CAN Bus converter serves as a solid foundation upon which many basic components can be built, including COM, USB, and Ethernet communications. ICP DAS has developed a series of DeviceNet/CANopen/ J1939 products, including PCI interface cards, Fieldbus converters, PACs, gateways and remote I/O modules. The technology provides complete hardware solutions to satisfy a wide variety of CAN-based applications that can effectively solve issues related to data acquisition and calculation, transmission distance extension, network topology limitations, communication interface transformation, and noise resistance. ICP DAS also supplies a wide range of software tools, which can help you to develop
