Description
Product name : S201M-C20 ABB Processor module
Product details:
ABB PLCs are robust and reliable control systems used to automate industrial processes. They consist of a central processing unit (CPU), input/output (I/O) modules, and communication modules, all housed in a modular design that allows for flexible configuration and expansion.
Key components typically include:
- CPUs: The brain of the PLC, responsible for executing the control program, managing I/O, and handling communication. ABB offers various CPUs with different processing speeds, memory capacities, and integrated communication ports (e.g., Ethernet, serial).
- I/O Modules: These modules connect the PLC to sensors (inputs) and actuators (outputs) in the field. They can be digital (on/off signals) or analog (variable signals) and come in various configurations and densities.
- Communication Modules: These modules enable the PLC to communicate with other devices, such as Human Machine Interfaces (HMIs), other PLCs, Supervisory Control and Data Acquisition (SCADA) systems, and enterprise-level networks. They support a wide range of industrial protocols (e.g., Modbus TCP, OPC UA, PROFINET, PROFIBUS DP, IEC 61850).
- Terminal Bases/Units: These provide the physical connection points for the modules and often include integrated backplane communication.
- Software: ABB’s Automation Builder is the integrated development environment (IDE) for programming and configuring their PLCs. It supports standard IEC 61131-3 programming languages like Ladder Diagram (LD), Function Block Diagram (FBD), Structured Text (ST), Instruction List (IL), and Sequential Function Chart (SFC). It also offers tools for multi-program download, OPC server functionality, and virtual commissioning.
2. Product Parameters (General)
Specific parameters vary greatly depending on the PLC series and individual module. However, here are some general parameters you can expect:
- CPU Performance:
- Processor Speed: Measured in microseconds (µs) per instruction. High-end CPUs offer very fast execution times.
- Program Memory: Ranges from kilobytes (KB) to megabytes (MB), determining the complexity of the program that can be stored.
- Data Memory: For storing process variables and internal data.
- I/O Capacity:
- Number of I/O points: From a few points for compact PLCs to thousands for large systems, expandable with I/O modules.
- Input/Output Type: Digital (e.g., 24V DC, 120V AC) and Analog (e.g., 0-10V, 4-20mA).
- Output Current: For digital outputs, specifies the maximum current per channel.
- Communication:
- Number and Type of Ports: Ethernet (RJ45), Serial (RS232, RS485), USB.
- Supported Protocols: Modbus TCP/RTU, OPC UA, PROFINET, EtherNet/IP, CANopen, PROFIBUS DP, IEC 61850 (for specific applications).
- Environmental Ratings:
- Operating Temperature: Standard range (e.g., 0-55°C) and extended range for XC variants (e.g., -40°C to +70°C).
- Humidity: Operating humidity range.
- Vibration and Shock Resistance: Important for industrial environments.
- Ingress Protection (IP) Rating: Against dust and water.
- Power Supply:

3. Product Advantages
- Scalability: The AC500 platform offers a wide range of CPUs and modules, allowing users to choose the right performance and I/O capacity for their specific application, from small machines to complex processes.
- Flexibility: Modular design allows for easy expansion and customization of I/O and communication capabilities. “All modules can be used with different CPUs” principle allows for quick response and cost-effectiveness.
- High Reliability: Designed for demanding industrial environments, ensuring stable and continuous operation. AC500-XC variants offer enhanced robustness for extreme conditions.
- Integrated Safety (AC500-S): Dedicated safety PLCs (SIL3, PL e) simplify the implementation of safety-critical applications, ensuring compliance with industry standards.
- Advanced Connectivity: Support for a wide array of industrial communication protocols, including Ethernet-based protocols like OPC UA and MQTT for secure data exchange with cloud platforms, facilitating Industry 4.0 and IoT applications.
- Powerful Programming Environment: Automation Builder provides a comprehensive and user-friendly environment for programming, configuration, and diagnostics, supporting all IEC 61131-3 languages.
- Cost-Effectiveness: The flexible and scalable nature helps optimize costs by providing solutions tailored to specific needs without over-specifying hardware.
- Long Product Lifespan: ABB’s commitment to product longevity and lifecycle management ensures long-term availability and support.
- Reduced Engineering Time: Features like virtual commissioning and standardized libraries in Automation Builder help reduce development and commissioning time.
4. Precautions for Use
- Electrical Safety:
- Always disconnect power to the PLC and all connected devices before wiring, connecting/disconnecting modules, or performing any maintenance.
- Ensure proper grounding of the PLC and control cabinet to prevent electrical noise and ensure safe operation.
- Run signal and power wiring separately to avoid interference (EMC).
- Use appropriate fuses or circuit breakers for overcurrent protection.
- Electrostatic Discharge (ESD) Protection:
- PLCs are sensitive to ESD. Always discharge static electricity by touching a grounded object or wearing an approved grounding wrist strap before handling components.
- Avoid touching connectors, pins, or internal circuit components.
- Store unused equipment in static-safe packaging.
- Environmental Conditions:
- Operate devices within their specified temperature and humidity ranges.
- Do not obstruct ventilation slots on the PLC modules to ensure proper cooling.
- Protect PLCs from excessive vibration, shock, dust, and moisture unless using a specifically designed “Extreme Conditions” variant (AC500-XC).
- Wiring:
- Ensure all wires are of adequate size to carry the correct current.
- Avoid splayed strands when wiring terminals; use ferrules if necessary.
- Ensure all connectors are wired correctly and fitted securely, avoiding overtightening.
- Battery Safety:
- Use only ABB approved lithium battery modules for backup.
- Do not open, recharge, or disassemble lithium batteries, as this can lead to overheating and explosion.
- Protect batteries from heat and fire, and store them in a dry place.
- Software and Programming:
- Always back up your PLC programs regularly.
- Implement robust safety logic in your program to ensure the system defaults to a safe state in case of power loss or unexpected events.
- Thoroughly test all program changes before deploying them in a live system.
