● 在原料粉磨、窑头、水泥粉磨、和总降压站等配电室各设置一现场控制站,以实现分散控制。现场控制站由S7400自动化站和分布式10(ET200M)构成,采用 Profibus-DP现场总线结构,同时通过 Modbus与一些现场电气设备连接
Chengdu Guanghua group company is specialized in the application, development and integration of industrial automation products. It is a long-term partner of Siemens. Our company has a lot of practical experience and successful cases in automation projects of building materials, metallurgy, chemical industry and other industries.
The case of SIEMENS PCS7 used in a cement plant's new dry process rotary kiln cement production DCS project is as follows:
● The system is composed of field control station and central control equipment to realize centralized monitoring and decentralized control. The field control station and central control equipment exchange data through industrial Ethernet composed of ring optical fiber network
● A field control station is set in the distribution rooms of raw material grinding, kiln head, cement grinding and general step-down station to realize decentralized control. The field control station is composed of S7400 automation station and et200m. It adopts PROFIBUS DP field bus structure and connects with some field electrical equipment through MODBUS
● The central control equipment is equipped with four operator stations, one engineer station and one @ p0s7 server. The redundant server / client structure is adopted to realize the centralized monitoring and operation of the whole production line, and the process information of the production line is transmitted to the factory information system through @ PCS7 server
