| Abstract: | The article describes a process control system based on ethernet and fieldbus technology. This system can complete parameter control, storage and analysis, such as temperature, pressure, flow rate and level. In the process of control, we use PID algorithm and realize isobaric water supply, then complete the stabilization of water tank. |
