ABB PM864AK01 3BSE018161R1 AC 800M Processor Unit

ABB PM864AK01 | 3BSE018161R1 | AC 800M Processor Unit

Functional Overview

The ABB PM864AK01 serves as a high-performance central processing hub for the AC 800M controller range within the 800xA automation platform. Engineered for industrial environments requiring high availability, this MPC862-based unit executes complex control logic for both continuous and batch processing. The processor excels in brownfield migrations and system expansions by maintaining compatibility across various 800xA hardware versions (4.0 through 6.0). Its design prioritizes deterministic performance, ensuring that critical control loops remain stable even under high communication and logic loads.

Key Operational Characteristics

• Integrated Communication: Features dual Ethernet channels for peer-to-peer communication and dedicated serial ports (COM3 and COM4) for peripheral connectivity.
• System Scalability: Supports up to 12 CEX-Bus modules and manages up to 96 I/O modules in non-redundant configurations.
• Comprehensive Hardware Kit: Provided as a complete assembly including the processor module, TP830 baseplate, bus terminators, and the necessary backup battery.
• Reliable Execution: Capable of running up to 32 concurrent control tasks with cycle times reaching 1 ms for time-critical applications.
• Memory Management: Utilizes 32 MB of RAM with over 23 MB dedicated to user applications, backed by Flash PROM for firmware storage and a lithium battery for data retention during power cycles.
