Industrial Production Stream-chain Boiler DCS Control System

With the production craftwork of the industrial production saturation stream-chain boiler and the actual request of the control system, DCS control systems based on PLC and network choices are introduced. Through the study and comparison of the control network and the communication mode, and with the consideration of the spread prospect in industrial production in future, profibus technology of German SIMENS company and the actual applied situation of industrial Ethernet technology are presented, which demonstrates maturity,reliability and advance of the two industrial network technolog ies. Especially they are fit for industrial spot which owes a lot of communication and high communication rate. Also through combining spot control facility's actual distribution, they can apply the configuration modes with concentration or distribution, satisfy the craftwork production and user demand at maximum level. It is shown that, with the core of DCS technology composed of PLC, and with the industry control network and configuration software, adopting profibus technology and industrial Ethernet communication technology can fulfil modern corporation production and management request fully.
