4. Product Introduction (Anti-Template)
When a process controller must keep scanning after a single CPU fault, the PM864AK01 provides the processing core for AC 800M systems. The kit ships with the PM864A processor board, TP830 baseplate, CEX-bus and ModuleBus terminators, RCU-link terminator, and backup battery. Dual Ethernet ports handle the Control Network while serial ports support configuration and service tools.
Running at 96 MHz with 32 MB of memory, the unit executes IEC 61131-3 applications down to 1 ms cycle times and supports full CPU redundancy with a maximum 10 ms switch-over. It is classified as Classic lifecycle status; ABB recommends the PM866AK01 family for new installations, but the PM864AK01 remains a direct replacement for existing 800xA systems that already use this generation.

5. QC, Procurement & Logistics SOP
- Inbound Verification – Origin is confirmed against ABB manufacturing records. Ordering code (3BSE018161R1), CPU and baseplate condition, terminator presence, and battery status are photographed and logged.
- Live Rig Testing – Kit is assembled on a test base, powered at 24 V DC, connected to a Control Network, and verified for boot, Ethernet link, serial communication, memory backup, and basic application download.
- QA & Anti-Static Packaging – After functional pass, connectors are protected, the battery is checked, and the complete kit is sealed in anti-static shielding with desiccant and humidity indicator.
- Global Logistics & Export Compliance – Classified under the correct HS code for industrial control processor units. Packaging is rated for air and sea freight vibration; lithium-battery shipping regulations are observed and export documentation is prepared to minimize customs delays.

6. Technical Pitfalls & Integration Warnings
Battery Installation Sequence – The backup battery must be installed only after the CPU has powered up and the memory-backup function is active (B LED behavior). Incorrect timing can leave the controller without retain data.
Redundancy Configuration Errors – Both CPUs in a redundant pair must be the same hardware revision and firmware level. Mixing generations or failing to configure the RCU link correctly prevents proper switch-over.
Terminator Omission – Missing CEX-bus or ModuleBus terminators causes communication errors or intermittent I/O faults. Always install the supplied TB850, TB807, and TB852 terminators.
Lifecycle & Compatibility – The PM864AK01 is Classic status and not RoHS 2 compliant for new installations. Using it in a new project or with newer 800xA software versions may require additional validation or force a migration to PM866/PM891 families.

7. Frequently Asked Questions (FAQ)
What is the realistic global lead time for a verified PM864AK01 kit?
Stock units normally ship within 1–3 business days after payment clearance. Air freight to major industrial regions typically adds 3–8 days once customs processing is complete. Lithium-battery regulations may add minor handling time.
Does the kit include everything needed to run?
Yes. It includes the PM864A CPU, TP830 baseplate, CEX-bus terminator, ModuleBus terminator, RCU-link terminator, and memory backup battery.
Is CPU redundancy supported?
Yes. The PM864AK01 supports redundant CPU configurations with a maximum switch-over time of 10 ms.
What is the processor speed and memory size?
96 MHz MPC862 processor with 32 MB RAM (approximately 23.5 MB available for the application).
Can this unit be used for new installations?
ABB classifies it as Classic and recommends the PM866AK01 (or later) for new projects. It remains valid as a spare or replacement for existing systems.
What Ethernet interfaces are provided?
Two RJ45 ports (CN1 and CN2) for connection to the Control Network (10 Mbit/s Ethernet).
Is a CompactFlash card included?
No. The interface is present for application and data storage, but the card itself is ordered separately if required.
