摘要：Application of WinCC and S7-400 dual-redundancy PLC controllers in a dense-phase transporting control system is introduced in this paper. The production process and the overall structure of the system are described in detail.STEP7 programming tool is used to compile the control program. The key technology of program design is described. Design of the functions of the monitoring system is performed on the basis of WinCC, including fabrication of the monitoring interface, design of configuration warning, design of the report system, and authority definition of user management. The system is featured by high reliability, excellent performance-cost ratio, and good extendibility and serviceability. It is the first choice for enterprises to carry out technical reform, tap the latent power, and improve efficiency.
