Product Introduction
The ABB 3BHB007211R0116 is a high-performance central processing unit (CPU) module from ABB’s AC800M programmable logic controller platform, widely deployed in continuous and batch process industries. Officially designated as the PM864AK01, this module serves as the computational backbone of medium-to-large automation systems within the ABB Ability™ System 800xA architecture. With 4 MB of program and data memory, dual-core processing, and native support for redundancy, the ABB 3BHB007211R0116 delivers deterministic control for applications where uptime and precision are non-negotiable.
Engineered for integration into complex DCS environments, the ABB 3BHB007211R0116 supports multiple communication protocols—including Ethernet/IP, Profibus DP, and ABB’s proprietary Modulebus—enabling seamless connectivity to remote I/O, drives, HMIs, and enterprise systems. Its role extends beyond logic execution: it hosts safety-related functions (when paired with appropriate firmware), executes motion coordination tasks, and provides real-time diagnostics for predictive maintenance. Whether used in a standalone PLC or as part of a fully redundant 800xA system, the ABB 3BHB007211R0116 ensures reliable, scalable control across power, water, mining, and chemical sectors.
Core Advantages and Technical Highlights
Core Advantages and Technical HighlightsDeterministic Performance for Mission-Critical Processes:
The ABB 3BHB007211R0116 executes Boolean logic in just 0.15 microseconds, enabling fast scan cycles even in large programs. Its dual-core architecture separates control tasks from communication handling, preventing network traffic from impacting I/O response—a critical advantage in high-speed or safety-related loops.

Built-In Redundancy Without Compromise:
Unlike add-on redundancy solutions, the ABB 3BHB007211R0116 supports true hot-standby operation when paired with an identical unit and synchronization link. Switchover occurs in <10 ms with zero process interruption. Both CPUs continuously compare states, and any discrepancy triggers an alarm before failure occurs.

Installation, Commissioning and Maintenance Instructions
Installation preparation:
Before installing the ABB 3BHB007211R0116, verify compatibility with your AC800M rail (e.g., TK811V015) and power supply module (e.g., SA811). Ensure the rail is grounded and free of debris. Slide the ABB 3BHB007211R0116 onto the DIN rail until it clicks into place—do not force the connectors. If configuring redundancy, install both CPUs side-by-side and connect the sync cable before powering up.

Maintenance suggestions:
The ABB 3BHB007211R0116 has no user-serviceable parts. Monitor CPU load and memory usage via Automation Builder or 800xA Workplace. In redundant systems, perform annual switchover tests to validate failover integrity. Replace the unit if the “RUN” LED flashes abnormally or if communication errors persist after network checks. Always keep a spare ABB 3BHB007211R0116 with identical firmware version for rapid replacement—firmware mismatches prevent redundancy pairing.
