Description
原料输送、固体配料、液体配料、料浆制备、喷雾干燥、后配料、成品计量等工序.系统设置两个控制室,一个为中控室,负责整条生产线的监控;另一个为后配料控制室,负责对后配料部分进行监控,后配料的实时数据通过PROFIBUS DP分布式I/O将瞬时流量等数据传送至中控室,同时接受中控室的给定流量.系统结构图如下:
—-控制站主机采用SIMATIC S7 414-2DP,并采用ET200M将现场I/O站通过PROFIBUS DP连接到中控室,后配料电子皮带秤及流量计控制采用两台SIMATIC S7-214,并通过CP 242-8 PROFIBUS DP处理器模板与S7 414-2DP通讯.
