ABB AC 800M Redundant CPU Architecture

The PM864AK02 uses dual PM864A processor units to provide redundant controller execution within ABB AC 800M systems. The configuration maintains synchronized CPU operation through the RCU-Link connection and supports controller availability through coordinated processor status monitoring.

Furthermore, the processor kit integrates CEX-Bus expansion capability through the TK850 cable. This interface supports communication between controller components and connected system modules. The architecture also supports I/O density scaling through ABB backplane and module communication structures.

The redundant processor arrangement requires two CPU units and dedicated synchronization hardware. The included TP830 baseplates provide the mechanical mounting structure, while TB807 terminators complete the ModuleBus configuration.

Backplane Bus Communication and Firmware Compatibility

The PM864AK02 belongs to the ABB System 800xA and AC 800M controller family. It communicates through ABB controller buses designed for deterministic industrial automation data exchange.

The processor unit supports ABB firmware compatibility management through the AC 800M controller platform. Therefore, firmware revisions must match the installed controller configuration and engineering system requirements before commissioning.

The redundant configuration uses synchronized processor execution rather than independent control operation. This structure allows the controller pair to exchange operational status and maintain consistent application execution.

Frequently Asked Questions

Q: What hardware components are included in the ABB 3BSE018164R1 PM864AK02 kit?
A: The kit includes two PM864A processor units, two TP830 baseplates, one TK850 CEX-Bus expansion cable, two TB807 ModuleBus terminators, one TK851 RCU-Link cable, and CPU backup batteries.

Q: Does the PM864AK02 operate as a single processor module?
A: No. The PM864AK02 is a redundant processor kit requiring two PM864A CPU units for redundant controller operation.

Q: What is the function of the TK851 cable in this configuration?
A: The TK851 RCU-Link cable provides the communication connection required for synchronization between redundant processor units.

Field Installation Guidelines

Install the PM864AK02 on the specified ABB AC 800M controller mounting structure using the supplied TP830 baseplates.

Verify that both processor units are correctly seated before applying system power. Ensure that the TK851 RCU-Link cable and TK850 CEX-Bus expansion cable are installed according to ABB wiring instructions.

Route communication cables separately from high-voltage power wiring to reduce electrical interference. Connect cable shields according to the cabinet grounding design and maintain proper protective earth continuity.

Before commissioning, confirm CPU firmware compatibility, ModuleBus termination installation, battery status, and redundant processor synchronization conditions through the engineering tool.
