If it is mainly analog control and there are many function operations,it is best to use dcs.dcs is much better than plc in terms of redundancy of controllers,i/o boards,communication networks,etc.,some advanced operations,and special requirements of the industry.Because plc adopts general monitoring software,it is easier to design the management information system of the enterprise.

如果主要是模拟量控制、并且函数运算很多，最好采用dcs。dcs在控制器、i/o板、通讯网络等的冗余方面，一些高级运算、行业的特殊要求方面都要比plc好的多。plc由于采用通用监控软件，在设计企业的管理信息系统方面，要容易一些。
