西门子1200程序设计案例 三种液体博途PLC博图多种液体HMI仿真液体混合、包含内容：①三种液体博途PLC与HMI仿真工程(博途V14或以上) 一份；②三种液体配套有IO点表+PLC接线图+主电路图+控制流程图 (CAD源文件可编辑);③三种液体博途仿真工程配套视频讲解一份；④赠送参考文章【基于PLC的三种液体控制系统设计】一份（pdf格式,共16页）；二、功能介绍：①总体控制要求：如面板图所示，本装置为三种液体混合模拟装置，由液面传感器SL1、SL2、SL3，液体A、B、C阀门与混合液阀门由电磁阀YV1、YV2、YV3、YV4，搅匀电机M，加热器H，温度传感器T组成。实现三种液体的混合，搅匀，加热等功能。②打开“启动”开关，装置投入运行时。首先液体A、B、C阀门关闭，混合液阀门打开20秒将容器放空后关闭。然后液体A阀门打开，液体A流入容器。当液面到达SL3时，SL3接通，关闭液体A阀门，打开液体B阀门。液面到达SL2时，关闭液体B阀门，打开液体C阀门。液面到达SL1时，关闭液体C阀门。③搅匀电机开始搅匀、加热器开始加热。当混合液体在6秒内达到要求温度，加热器停
