Functional Features
- Core Functions of the Controller
- Modular Design: Supports free combination of CPU modules, input/output (I/O) modules, communication modules, power modules, etc., adapting to automation needs of different scales.
- High-Performance Processing:
- Equipped with ARM or PowerPC processors, supporting high-speed logic operations, timers, counters, and other functions.
- Processing speed: Capable of executing tens of thousands of instructions per second (e.g., 0.1–1ms/kB program execution speed).
- Programming Language Compatibility: Supports IEC 61131-3 standard programming languages, such as Ladder Diagram (LD), Structured Text (ST), Function Block Diagram (FBD), etc.
- Communication and Expansion Capabilities
- Built-in Communication Interfaces:
- May integrate Ethernet (supporting Modbus TCP, Profinet, etc.) and RS-485 (Modbus RTU) interfaces.
- If it is a communication module (e.g., PB101), it may support industrial bus protocols such as Profibus DP, EtherCAT, and CANopen.
- Expansion Capability:
- Can connect up to dozens of I/O modules, supporting digital (DI/DO), analog (AI/AO), high-speed counting, pulse output, and other functions.
- Reliability and Environmental Adaptability
- Industrial-Grade Design:
- Operating temperature: -20°C ~ +60°C (wide-temperature models may have a broader range).
- Protection level: IP20 (standard, suitable for installation in control cabinets); some modules support harsher environments (e.g., IP65 protection).
- Anti-Interference Capability: Complies with IEC 61000 electromagnetic compatibility standards, with excellent vibration and impact resistance, suitable for industrial field applications.
- Programming and Maintenance
- Software Tools: Uses ABB’s Control Builder M or AC500-ETH programming software, supporting online debugging, firmware upgrades, and fault diagnosis.
- Fault Diagnosis:
- Module status indicator lights (e.g., power, operation, fault, communication status) display real-time operating conditions.
- Supports remote monitoring and alarming (e.g., sending fault information to HMI or SCADA systems via Ethernet).

Working Principle
- Central Processing Unit (CPU)
- The core computing unit is responsible for executing user programs, processing logic control, and data operations.
- May adopt high-performance microprocessors (such as ARM or specialized industrial-grade chips) with real-time operating systems (RTOS) to ensure fast instruction response (nanosecond-level processing speed).
- Memory System
- Program Memory (ROM): Stores system firmware, boot programs, and user-written control logic programs (e.g., ladder diagrams, ST structured text, etc.).
- Data Memory (RAM): Temporarily stores input/output (I/O) statuses, intermediate variables, and real-time data (e.g., sensor readings).
- Input/Output (I/O) Modules
- Digital I/O: Connects to devices such as buttons, relays, and switches to receive ON/OFF signals (e.g., motor start/stop commands) or output control signals (e.g., solenoid valve drives).
- Analog I/O: Processes continuous signals (e.g., 4–20mA current, 0–10V voltage) for collecting sensor data (e.g., temperature, pressure, flow) or adjusting output parameters of frequency converters and servo systems.
- Special Function Modules (Optional): Supports high-speed counting, pulse output (e.g., servo motor control), communication expansion (e.g., Profibus, Ethernet/IP), etc.
- Communication Interfaces
- Serial communication: RS-232/485 (Modbus RTU).
- Industrial Ethernet: Profinet, Ethernet/IP, Modbus TCP.
- Fieldbus: Profibus DP, CANopen.
- Supports multiple industrial communication protocols, such as:
- Used to connect to host computers (SCADA systems), human-machine interfaces (HMI), other controllers, or smart devices for data interaction and remote monitoring.
- Power Module
- Provides stable power for internal controller components (e.g., 24VDC). Some models support wide voltage input (e.g., 85–264VAC) with surge and overvoltage protection.
Application Scenarios
- Manufacturing: Production line control, assembly equipment, packaging machinery, etc.
- Process Automation: Chemical, water treatment, and HVAC (heating, ventilation, and air conditioning) systems.
- Energy and Power: Substation automation, small-scale power generation equipment control.
- Building Automation: Elevator control, intelligent building management systems (BMS).
