III. Functional Features

Real-time Process Diagnosis: It has a powerful real-time diagnosis function. By continuously monitoring and analyzing the collected process parameters (such as temperature, pressure, flow, etc.), using advanced fault diagnosis algorithms, it can accurately identify early fault signs of equipment, such as sensor drift, valve jamming, abnormal motor vibration, etc., and timely issue sound and light alarm signals, while recording fault information. It provides maintenance personnel with accurate basis for fault location, effectively avoiding production shutdown caused by fault expansion.

Data Trend Analysis: It can store and analyze the collected historical data, generating intuitive data trend charts, such as temperature change curves and pressure fluctuation trends. Through the analysis of these trends, operators can clearly understand the change rules of the production process, predict the development trend of process parameters, provide a scientific basis for production process optimization and equipment maintenance plan formulation, and help enterprises achieve refined production management.

Flexible Control Logic: It supports user-defined control logic, and complex control programs can be written through dedicated programming software to achieve precise control of industrial production processes. For example, automatically adjusting valve opening and controlling motor speed according to different process conditions, meeting personalized control needs in different industrial scenarios, and improving the automation level and control accuracy of the production process.

Remote Monitoring and Management: With the help of Ethernet interfaces and related communication protocols, remote monitoring and management functions can be realized. Operators in the remote monitoring center can real-time view the operating status of PDP601, production process parameters, and fault alarm information, and can remotely modify control parameters, start and stop equipment, etc. This greatly improves the operation and maintenance efficiency of industrial control systems, especially suitable for centralized management of large industrial plants or decentralized production equipment.
