用西门子S7-200PLC实现对投放明矾进行自动化改造。该自动投矾系统由三个主要部分组成:水质传感器(浊度、温度、PH、流量)、控制电柜、组态监控。其中控制电柜包括西门子S7-200PLC,用于采集传感器数据,通信协议是MODBUS协议;还有EM232模拟量输出模块是控制变频器的主要模块;以及CP243-1网络模块,用于连接中控室组态软件。
Using Siemens S7-200PLC to achieve the alum for automation transformation. The automatic cast alum system consists of three main components: water quality sensors (turbidity, temperature, PH, flow), control panel, configuration monitoring. Which control panel, including Siemens S7-200PLC, used to collect sensor data, the communication protocol is MODBUS protocol; there EM232 analog output module is the main control inverter; and CP243-1 network module for connecting the control room group State software.
