　　PM865K01 3BSE031151R1 Other Names:

　　Processor Unit PM865K01 3BSE031151R1

　　PM865K01 3BSE031151R1  Communication Unit

　　Input/Output Unit PM865K01 3BSE031151R1

　　Technical Features

　　Hardware Configuration: Equipped with a multi-core CPU, typical program memory ≥32MB (expandable), supports external storage (such as CF cards). Features two RJ45 Ethernet ports (CN1/CN2, supporting 10/100/1000 Mbps) and two serial ports (COM3 is RS-232C, COM4 is an isolated port) to meet high-speed data transmission and device connectivity requirements.

　　Environmental adaptability: Operating temperature range -40°C to +70°C, IP20 protection rating (control cabinet installation required), 24V DC power requirement, power consumption approximately 10-20W, suitable for wide-temperature industrial environments.

　　Expansion capabilities: Supports S800/S900 I/O module expansion, compatible with industrial protocols such as Modbus, Profibus DP, and OPC UA. Remote I/O can be expanded via modules such as CI854 and CI861.

　　Communication capabilities: Equipped with two RJ45 Ethernet ports (CN1/CN2, supporting 10/100/1000Mbps) and two serial ports (COM3 is RS-232C, COM4 is an isolated port), compatible with industrial protocols such as Modbus TCP/IP, Profibus DP, and OPC UA. Supports CEX bus and S800/S900 I/O module expansion.

　　Redundancy Mechanisms

　　CPU Redundancy: Supports dual-CPU hot standby switching. In the event of a primary CPU failure, the backup CPU seamlessly takes over, ensuring continuous system operation.

　　Bus Redundancy: The CEX bus, communication interfaces, and I/O modules support redundant configuration. High integrity functionality is achieved through SM81x modules and SIL-certified software, complying with IEC 61508 and TÜV certifications, suitable for safety-critical process control.

　　Power Supply Redundancy: Optional redundant power supply modules ensure power supply stability.

　　Hardware Redundancy: Dual Ethernet ports support redundant network connections. The CEX bus and S800 I/O modules can be configured with redundant paths to avoid single points of failure.

　　Diagnosis and Maintenance: Built-in hardware identifier (unique Ethernet address) and real-time clock synchronization (CNCP protocol) support remote diagnostics and rapid fault switching.

　　Maintenance: Compact size, easy installation, supports online program modification and firmware updates, and enables efficient programming and monitoring with Control Builder M software.

　　Application Scenarios

　　Process Automation: DCS (Distributed Control Systems) for industries such as petroleum, chemical, and power, achieving high-precision process control.

　　Discrete Manufacturing: Automated production lines in industries such as automotive and metallurgy, improving production efficiency and product quality.

　　Large-Scale Systems: SCADA systems and intelligent power distribution systems (such as the EcoStruxure Power solution), supporting full lifecycle hardware and software collaboration and digital management.

　　Safety-Critical Scenarios: Suitable for environments requiring high safety, such as SIL-certified process control, generator excitation control in power systems, and monitoring of critical equipment in factory automation.

　　System Integration: As the core of the ABB AC 800M system, it can collaborate with 800xA control software and intelligent power distribution edge control software (such as POA/PO/POT) to achieve full lifecycle digital management.

　　Certifications and Standards:

　　Complies with industry standards such as CE, UL, and IEC, and is SIL 2/SIL 3 certified, ensuring reliability in safety-critical applications.

　　Built-in hardware self-test and fault logging functions, supports ABB 800xA or Compact Control Builder programming software, and is compatible with Industrial Internet of Things (IIoT) architectures.

　　Additional Information

　　Physical Specifications: Approximately 119×186×135mm in size, weighing 1.2kg. Mounting options include DIN rail or rack mounting.

　　Certifications and Compliance:Compliant with RoHS and WEEE directives, TUV SIL 2/3 certified, suitable for hazardous areas (e.g., cULus Class 1, Zone 2).

　　Maintenance Recommendations:

　　Power Management: Use a UPS or voltage regulator to ensure stable power supply and prevent voltage fluctuations from affecting equipment operation.

　　Data Backup: Regularly export programs and configuration files to prevent data loss.

　　Performance Monitoring:Monitor CPU load to prevent excessive program resource consumption; regularly update firmware to improve stability.

　　Environmental Inspection: Regularly inspect the installation environment (temperature, humidity, vibration) to ensure it meets equipment operating requirements.

　　Comparison with Similar Products:

　　Compared to the AC 800F: The PM864AK01 3BSE018161R1 offers advantages in redundancy, processing power, and scalability, supporting more complex control logic and a larger I/O scale.

　　Alternative solutions: Selection depends on specific application requirements. For example, for extremely high redundancy requirements, consider the PM891K02 3BSE053242R1 from the same series, or combine it with other ABB controllers (such as the AC 800F) to achieve multi-level redundancy.

　　The PM865K01 3BSE031151R1 , with its powerful redundancy capabilities, flexible communication interfaces, and high reliability, has become a core component in industrial automation to ensure continuous system operation and safety. It is suitable for critical application scenarios with extremely high stability and real-time requirements.
