Description

PM862K01 3BSE076940R1: Product Overview
The PM862K01 3BSE076940R1 is a high-availability CPU module within ABB’s AC800M series of programmable logic controllers (PLCs) and distributed control systems (DCS). Its role is to serve as the central processing unit for medium- to large-scale industrial automation applications, positioned as the core controller in rack-mounted systems. It executes user-defined control logic (via IEC 61131-3 languages), processes data from distributed I/O modules (digital/analog), and manages communication with field devices, peer controllers, and supervisory systems.
Functionally, the CPU handles cyclic and acyclic tasks: cyclic tasks manage real-time I/O updates (e.g., sensor readings, actuator commands) with deterministic timing, while acyclic tasks handle diagnostics, configuration changes, and communication with higher-level systems (e.g., SCADA). As part of the AC800M family, it leverages a platform optimized for process automation, offering modular redundancy (active/standby), compatibility with ABB Control Builder M engineering software, and support for multiple industrial protocols. Benefits include enhanced system availability, simplified scalability, and reduced engineering effort through reusable code libraries.

Core Features & Customer Value​
Redundant architecture for high availability: The module supports active/standby configuration, with automatic failover in ≤50ms. For customers in continuous process industries (e.g., chemical manufacturing), this eliminates single-point controller failures, preventing unplanned shutdowns and safeguarding critical assets like reactors or turbines.
High-performance processing: The 1 GHz PowerPC processor and 512MB RAM enable efficient execution of complex control logic (e.g., PID loops, batch sequencing) and large data sets. Engineers can run advanced algorithms without compromising scan time, ensuring precise control of multivariable processes like distillation columns.
Flexible communication integration: Native support for Ethernet/IP, Profibus DP, and Modbus TCP allows seamless connection to ABB S800 I/O, third-party PLCs (e.g., Siemens S7), and SCADA systems. This avoids protocol converters, reducing wiring complexity and integration costs. For example, in a water treatment plant, it can poll 100+ remote sensors via Profibus DP while transmitting data to a central SCADA via Ethernet/IP.
Integrated engineering tools: Compatibility with Control Builder M streamlines programming, debugging, and commissioning. Reusable function blocks (e.g., motor control, valve sequencing) cut development time by 20-30%, while online monitoring aids real-time troubleshooting.

Typical Applications​
In a petroleum refinery’s catalytic reformer, the PM862K01 3BSE076940R1 serves as the primary controller, managing 500+ I/O points (temperature, pressure, flow) via AC800M I/O modules. Its redundant configuration ensures uninterrupted control during catalyst regeneration cycles, while Ethernet/IP transmits data to the plant’s 800xA DCS for optimization.
At a power plant’s boiler feedwater system, the CPU executes coordinated control of pumps and valves, using PID loops to maintain drum level. Its -25°C cold-start capability supports outdoor installations, and Modbus TCP integrates with the plant’s historian for compliance reporting.
In a pharmaceutical batch reactor, the module runs sequential control logic for ingredient dosing and temperature ramping. The 2GB Flash stores recipe data, and hot-swappable design allows maintenance during planned turnarounds without halting production.
