♦Dual network port design facilitates the development of dual machine redundancy solutions

Important industrial communication sites typically require highly reliable redundancy designs, including redundant control layer communication hosts, redundant communication links, and redundant communication equipment. Therefore, the architecture and software design of the entire system must be able to meet this redundancy requirement. BBSea NC616E dual port communication server, designed with dual ports, supports 2 IP addresses and 2 MAC addresses, and can be connected across two independent networks. This is a prerequisite for developing a dual network redundancy plan.

♦Multi session function, enabling multiple hosts to access the same serial port simultaneously

♦A comprehensive security mechanism that can restrict access permissions for both primary and backup machines

BBSea IO Server provides a series of network security mechanisms, which not only prevent device security, but also effectively control the read and write permissions of the host and backup machines to the IOServer serial port, preventing mutual interference between the host and backup machines.

Create two users on IO Server, each with different permissions. When the host establishes a TCP connection with the corresponding serial port of IO Server, the host and backup authenticate with IO Server under different identities to obtain different permissions.

♦For dedicated APIs that may be used for "dual machine redundancy" or "dual network redundancy"

BBSea IO Server provides practical APIs and sample programs for software developers to improve their systems.

int WINAPI connect_device(char * ipaddr)

/*Check if the communication between PC and IO Server is normal*/

int WINAPI reset_device(unsigned char * mac,char *

ip,char * pwd);

/*Reset IO Server*/

int WINAPI reset_device_ports(unsigned char * mac,char * ip,char * pwd,unsigned long ports);

/*Reset a certain serial port or ports of IO Server*/
