| Abstract: | The water treatment automatic control system integrated by PLC and computer consists of up-posting machine, adapter and PLC. The system is capable to monitor the operation of water treatment system, acquire and calculate data to identify the effectiveness of desalting device. It has also the capability for automatic control and adjustment of operation conditions of device. The communication between the host monitor computer and PLC extension is carried out by RS-232/422 converter. The communication process between the computer and individual PLC uses the transfer control mode with command and response. The system can improve the monitor level of the whole water treatment system to guarantee the safe and economic operation of the makeup water treatment system. |
