Driven by today's global Industry 4.0 wave, the stability and reliability of industrial automation systems have become an important guarantee for the continuous and efficient operation of enterprises. However, single point of failure has always been a difficult problem in the industrial field, which not only affects the production efficiency, but also may bring serious security risks. In this context, Tianjin Changda Technology Co., Ltd. with its deep accumulation and innovative spirit in the field of industrial automation redundancy technology, is gradually leading the industry to a more stable and efficient development path.

In an automated system, a single point of failure is any electrical, mechanical, software, or other component failure in a system that can cause the entire system to stop working. Once this failure occurs, it may cause production stagnation, equipment damage and even safety accidents, which will bring heavy losses to the enterprise. Therefore, how to avoid single point of failure and improve the redundancy and elasticity of the system is always the key problem in the design of automation system.

The basic principle of redundant design is to ensure that if one part of the system fails, the other parts will still function properly by adding additional components or paths. Common redundancy methods include power supply redundancy, sensor and meter redundancy, programmable logic controller (PLC) and hardwired control redundancy, and user visualization/control interface redundancy such as human machine interface (HMI), monitoring and data acquisition (SCADA). These methods can improve the redundancy and elasticity of the system at different levels to ensure the continuous operation of the system.

The dual bus redundancy system of T-3517 and T-3515 of Tianjin Changdatong Technology Co., Ltd. is designed based on this principle. The system adopts dual bus architecture, and connects each control node through two independent communication buses, ensuring that when one bus fails, the other bus can continue to transmit data and control instructions. This design not only improves the communication reliability of the system, but also enables the system to quickly switch to the standby bus in case of failure, ensuring the continuous operation of the system.

With excellent stability and reliability, the system builds a solid defense line for industrial automation systems, effectively dealing with the single point of failure, a long-standing problem in the industry, and provides a strong guarantee for the production efficiency and safe operation of enterprises.

With its profound technology accumulation and innovative spirit, Tianjin Changdatong Technology Co., Ltd. has achieved remarkable results in the field of industrial automation redundancy technology. In the future, the company will continue to cultivate this field, and continue to introduce more advanced and reliable redundancy technology solutions, contributing to the sustainable and efficient operation of the enterprise and the innovative development of the industry.
