Application scenarios

Water treatment: GE 90-70 series PLC is adopted, and the redundant communication module IC687RCM711B is configured. In the water treatment system, the control of multiple water pumps and valves as well as the monitoring of water quality parameters are involved. Through this redundant communication module, data synchronization between the primary and backup cpus is ensured. Even if one CPU malfunctions, the other can quickly take over the control, ensuring the stable operation of the water treatment process and avoiding the shutdown of the water treatment system due to communication failures. Affect the normal production of thermal power plants.

Automotive manufacturing automation: In the automotive manufacturing process, a large number of robots and automated equipment work in coordination, and the reliability of communication is required to be extremely high. The IC687RCM711B redundant communication module is applied in the control system of the production line to connect the PLC with the controllers of each device. In the vehicle body welding process, it ensures the real-time transmission of instructions and status synchronization among multiple welding robots. When a communication link fails, it can automatically switch to the backup link to prevent welding quality issues or production line stagnation, thereby enhancing production efficiency and product quality.

Rail transit signal control system: The rail transit signal system has extremely strict requirements for safety and reliability. The IC687RCM711B redundant communication module is applied in this system and is responsible for the communication redundancy between the on-board signal equipment and the ground signal control center. It ensures the reliable transmission of key data such as speed instructions and position information during train operation. Even in complex electromagnetic environments or equipment failures, it can guarantee the normal operation of the signal system and ensure the safe operation of the train.

Petrochemical production process: The petrochemical production process involves numerous complex chemical reactions and material transfers, which have extremely high requirements for the precise control of process parameters and the stability of the system. The IC687RCM711B redundant communication module is applied in the distributed control system (DCS) of enterprises, connecting various control stations and field instruments. It ensures the real-time synchronization of parameter data such as temperature, pressure and flow rate between the main and backup controllers. When the main controller malfunctions, the backup controller can quickly and seamlessly take over the control, avoiding the loss of control of process parameters due to communication interruption and reducing the risk of safety accidents.
