BC-ECR-B is a “Industrial Cloud Router” based on Ethernet services, which can be used with “BEACON Intelligent Cloud Platform” via Ethernet without renting telecommunications lines. The control center can directly use Ethernet to remotely access the “cloud router” via “BEACON Intelligent Cloud Platform”, and pass the “cloud router” to multiple remote devices in the same network segment for program upload and download, data monitoring, control, collection, and device maintenance. These remote devices include PLC, RTU, DCS systems, instruments, and electrical testing instruments. The “cloud router” has a scheduled cloud link recovery function to ensure communication quality. It supports communication data channel encryption, device certificate verification encryption, firewall, IP address and MAC address filtering, and guarantees the security of communication.
