Processor: Adopts an advanced microprocessor for fast execution of control algorithms, with high processing capabilities to handle complex control tasks.

Memory: RAM is generally 256MB or more, depending on the configuration; flash memory is 512MB to 1GB for program storage and data recording, and some configurations also support memory expansion.

Power Supply: The operating voltage is typically 24V DC, and redundant power supply can be selected to enhance system reliability in critical applications.

Dimensions: Approximately 150mm in width, 200mm in height, and 120mm in depth, with specific dimensions varying depending on the module configuration.

Data Acquisition

Program Execution
The microprocessor in the module reads the status of input signals from the input image register according to the pre-written control program and processes them based on instructions such as logical operations, comparisons, and arithmetic operations in the program. Control programs are typically written in programming languages such as Ladder Logic (LD), Function Block Diagram (FBD), and Structured Text (ST). For example, compare the set values of temperature and pressure with the actual acquired values to determine whether to start or stop a device or adjust the device's operating parameters.

Data Processing

Output Control

Communication Function
Supports multiple industrial communication protocols such as Ethernet/IP (Modbus TCP), Profibus DP, Modbus RTU, CANopen, etc. Through these protocols, the module can exchange and communicate data with other devices (such as upper-level monitoring systems, other PLC modules, intelligent instruments, etc.). For example, upload the acquired data to the upper-level computer for display and analysis, while receiving control instructions sent by the upper-level computer to achieve remote monitoring and centralized management.

Diagnosis and Self-protection
Built-in diagnostic functions real-time monitor the module's own operating status, including power status, processor status, I/O channel status, etc. When a fault is detected, it will issue a corresponding alarm signal and store the fault information in the register for engineers to troubleshoot. At the same time, the module also has certain self-protection functions, such as taking corresponding protective measures in case of power failure, communication failure, or program operation errors to avoid damage to field devices.

Energy Management: Can be applied to power generation and distribution systems to achieve monitoring and control of power generation equipment, power grid dispatching and management, power quality monitoring and regulation, etc., to ensure stable operation and efficient power supply of the power system.

Railway Automation: In the railway field, it can be used for train operation control, signal system management, station automated operation, etc., such as controlling switch conversion, signal light display, train entry and exit, etc., to improve the safety and efficiency of railway transportation.

Industrial Automation: Suitable for automation control of various industrial production processes, such as production line control, robot control, material handling system control in manufacturing; oil and gas extraction, transportation, and processing control in the petroleum and natural gas industry; chemical reaction process control and process monitoring in the chemical industry, etc.

Building Automation: Can be used for control of building HVAC (Heating, Ventilation, and Air Conditioning) systems, lighting systems, elevator control system management, etc., to achieve intelligent management of buildings and improve energy utilization efficiency and comfort.
