FAQs
Q1: What is the primary function of the PM864AK01?
It is a processor unit kit for the AC 800M controller platform, responsible for executing control logic, managing data processing, and coordinating communication with I/O modules in ABB Ability™ System 800xA. It is designed for medium-to-large process control applications in industries such as chemical, power, and metallurgy.
Q2: Does the PM864AK01 support redundancy?
Yes. The processor supports full CPU redundancy, covering CPU, CEX-Bus, communication interfaces, and S800 I/O. In a redundant pair configuration, the switchover time is ≤10 ms, ensuring uninterrupted operation in critical processes.
Q3: What is included in the PM864AK01 kit?
The complete kit includes: PM864A CPU, TP830 Baseplate (115 mm width), TB850 CEX-Bus Terminator, TB807 ModuleBus Terminator, TB852 RCU-Link Terminator, Memory Backup Battery (4943013-6), and 4-pos Power Plug.
Q4: What software is required to program this controller?
The PM864AK01 is configured using ABB Control Builder M (Compact Control Builder) within the 800xA engineering environment. It supports IEC 61131-3 programming languages and is compatible with System 800xA version 6.0.2 and onwards.
Q5: What are the common causes of CPU failing to enter RUN mode?
Common causes include:
-
Battery failure: The PM864AK01 uses a lithium backup battery (4943013-6) to retain SRAM data. If the battery is depleted, program data may be lost on power cycle. Replace the battery while power is ON to prevent data loss.
-
Terminator issues: Missing or improperly installed TB850 (CEX-Bus), TB807 (ModuleBus), or TB852 (RCU-Link) terminators can cause communication errors and prevent the CPU from entering RUN mode.
-
Baseplate seating: Verify that the CPU is fully engaged with the TP830 baseplate to ensure reliable backplane communication.
