从控制角度谈PLC、DCS及FCS三大系统的差异

Discussion on the difference of PLC,DCS and FCS system from the angle of the control

从PLC、DCS及FCS三大控制系统的基本特点入手,对PLC、DCS及FCS三大控制系统之间的差异从控制的角度进行分析,同时对控制系统发展的前景进行了阐述。

Three systems, programmable controller （PLC）, dispersion control system （DCS） and field bus control system（FCS）, experience every process of control system in electric power plant, which are tightly connected and also have essential difference with each other. Analyzes characteristic and difference among three systems, PLC, DCS and FCS, from the angle of control.
