A Cement Enterprise Co., Ltd.
The second-phase cement 4500t/d clinker cement production line of a cement enterprise is a new project.
Starting from various process requirements, it reflects the optimal design, optimal control and optimal investment.
1. The PlantPAX control system, currently the most high-end product of Rockwell Automation, is used, which is the most widely used and most mature control system in cement. It has advanced communication capabilities and the latest I/O technology, and also provides high-speed discrete control, process control, coordinated drive control, motion control, batch control and safety control. SIL2 certified for high reliability.
2. The server/clinet structure is adopted, the server and communication are configured in pairs, and the two servers are standby for each other. If any one server fails, the other server can be switched without disturbance.
3. Adopt industrial-grade managed switches, support ring network technology, and the self-recovery time of ring network failure is less than 20ms.
1. The first project in Asia that adopts the PlantPAX control system;
2. The whole plant adopts Rockwell L8 series controllers, including waste heat power generation.
3. The HMI control layer and the IO control layer are layered through the management switch to achieve physical isolation;
4. The three-layer network structure adopts the three-ring parallel ring network mode at the same time, IO group ring, the main station and the sub-station realize the equipment-level group ring, and the communication group ring between the master stations.
