- 32-bit 200 MHz high-speed industrial processor and large-capacity memory realize fast processing of complex process control logic and high-precision analog signal calculation, the program scan cycle is as low as 1 ms, meeting the high real-time requirements of industrial process control.
- Built-in rich dedicated process control algorithm library (PID self-tuning, cascade, ratio, feedforward, batch control) eliminates the need for secondary development of complex control algorithms by engineers, greatly reducing the design time of the process control system and improving the control accuracy.
- PID self-tuning function automatically adjusts the PID parameters according to the characteristics of the controlled object, realizing the optimal control of the process parameters without manual debugging, and adapting to the change of the controlled object characteristics in the production process, with strong adaptability.
- Support up to 500 recipe storage and on-site call, realize the fast switching of different production processes and parameters, which is suitable for batch production lines in the food, beverage, pharmaceutical and other industries, and improve the production efficiency and flexibility of the equipment.
- Multi-communication interface and multi-protocol support realize the seamless connection of the process control system with upper-level SCADA, HMI, industrial computers and industrial fieldbus (Profibus-DP), and support OPC DA protocol to realize data interaction with the upper-level management system, building a complete industrial control network.
- 16-bit high-precision analog signal processing and floating-point arithmetic ensure the accurate collection and calculation of process parameters such as temperature, pressure, flow and liquid level, and the high sampling rate (≤1 ms per channel) realizes the real-time monitoring and control of the process parameters.
- Support hot swapping of I/O modules, which can replace the faulty I/O module without shutting down the PLC system, effectively reducing the downtime of the production line and improving the maintainability and availability of the process control system.
- Comprehensive power supply protection functions (overvoltage, reverse polarity, surge) effectively protect the CPU module from damage caused by power supply abnormalities in the industrial field, and the battery-backed RAM ensures that the process data and configuration parameters are not lost during power failure.
- IEC 61131-3 standard programming language and drag-and-drop function block operation realize the fast development of the process control program, and the online debugging and online modification functions facilitate on-site debugging and parameter adjustment of the system without stopping the production line.
- The module is the core of the AEG Modicon 890 series process control PLC system, fully compatible with all Modicon 890 series I/O, communication and functional modules, plug-and-play, and can be flexibly configured according to the process control requirements, with strong system scalability.
