Description

The ABB PM864AK01(Order Code:3BSE018161R1)is a high-performance central processing unit(CPU)module for ABB’s AC 800M programmable automation controller platform,designed for use in the System 800xA distributed control system.It delivers deterministic real-time control for medium-complexity applications in process industries such as power generation,oil&gas,water treatment,and mining.With integrated communication interfaces,large program memory,and support for both local and remote I/O,the PM864AK01 provides a robust,scalable foundation for modern industrial automation—while enabling seamless migration from legacy systems like Bailey INFI 90.

🔍Note:The PM864AK01 is a non-redundant CPU.For redundant configurations,consider the PM865A or PM866A series.

Application Scenarios

At a district cooling plant in Dubai,engineers replaced aging Bailey controllers with a new AC 800M system centered on the PM864AK01 3BSE018161R1.The CPU managed 1,200 I/O points across six remote racks via Profibus DP,executed complex chiller sequencing logic,and communicated setpoints to VFDs over Modbus TCP—all within a 0.8 ms scan cycle.During summer peak loads,the system maintained chilled water temperature within±0.5°C,reducing energy consumption by 14%.The built-in web server allowed facility managers to monitor CPU load and I/O status remotely via tablet—without requiring engineering software.

Technical Principles and Innovative Values

Deterministic Real-Time Kernel:Ensures consistent scan times regardless of communication load—critical for motion coordination and safety interlocks.

Dual-Ethernet Architecture:Separates engineering traffic(Port 1)from field communication(Port 2),enhancing cybersecurity and performance.

Legacy Migration Ready:Supports import of Bailey INFI 90 function blocks and logic structures,reducing re-engineering effort by up to 70%.

Integrated Web Server:Provides real-time diagnostics,firmware version,IP configuration,and I/O status without third-party tools.

Scalable I/O Topology:Connects to local TB5xx I/O bases and remote stations(e.g.,BC810,BC25)over multiple fieldbuses simultaneously.

Application Cases and Industry Value

In a gold processing plant in Australia,the PM864AK01 controlled a cyanide leaching circuit with strict environmental compliance requirements.It synchronized pH dosing pumps,ORP sensors,and flow meters across three skids using Profibus DP and Modbus TCP.The CPU’s retentive memory preserved batch totals during brief grid outages,ensuring regulatory reporting accuracy.Over two years,the system achieved 99.98%uptime,and the modular design allowed easy addition of new thickener controls without replacing the CPU.
