Abstract : This paper introduces the application of the 3D force control configuration software PCAuto2.62 in a wastewater treatment automatic control system, as well as the system's composition, functions, and application effects. This system combines industrial control software with intelligent instruments, frequency converters, and PID controllers to design a complete engineering monitoring system, achieving constant pressure water supply and remote monitoring functions. Keywords : Configuration software; constant pressure water supply; monitoring and control; RS485 network In the past 20 years, with the development of computer hardware and software technology, a large number of new computer technologies have been increasingly applied in automated control systems. Simultaneously, with the continuous progress and development of microcomputer technology and automatic control technology, many fields have introduced computer-aided automatic detection and control technology. Furthermore, with the deepening and development of research in various fields, the requirements for computer-aided automatic measurement and control systems are becoming increasingly higher. Industrial configuration software emerged during this period as an advanced industrial control software package. It integrates process control design, on-site operation, and factory resource management, bringing together various production systems, applications, and information exchanges within an enterprise to achieve optimal management. With the increasing automation of enterprise production, the utilization of new equipment, and the refinement of production management, higher requirements are placed on the monitoring of the process flow. The wastewater treatment process at Shandong Aluminum urgently needs an automated control system. This system must be able to monitor the entire wastewater treatment system's operation, track equipment status, and support various control modes including manual, semi-automatic, and fully automatic control, as well as provide historical data, reports, and alarm analysis.
