Application of Fieldbus-Based Control System in Cement Production

This paper mainly describes an application of fieldbus control system (FCS) in a newly built NSP cement plant based on a concept of totally integrated automation (TIA). The system utilizes Prefabs and Ethernet combined with powerful SIEMENS PCS7 and Cemat software to configure a double-layer network, providing a convenient, advanced and flexible solution to cement automatic production. After describing hardware and software used in the system, this paper presents details of network configuration and functions of this advanced FCS system. Especially, three different network configuration modes between master CPUs and slave devices including frequency converters, gas analyzer, ET200M remote I/Os and other intelligent devices via Profibus-DP protocol are discussed.
