PM866AK01 3BSE076939R1 Processor Unit (Processor Unit/CPU Module) forms part of ABB's AC 800M controller series (AC 800M Controller Series), one of the core industrial PLC/DCS control components. Within this unit lies one fast processor along with memory, communication ports, timing functions, and site diagnostic tools. It serves as one of the key components needed to create an automation control platform through ABB (eg, 800xA).
When purchasing PM866AK01, it is recommended:
Clarify the system scale and control requirements.
Cooperate with other AC 800M or 800xA system modules;
Pay attention to spare parts compatibility and long-term maintenance support.
Ensure that engineers are familiar with the 800xA control Builder configuration process.

Product Details
3BSE076939R1 PM866AK01 is often used together with other modules of the ABB AC 800M controller system, and is integrated into distributed control through the CEX control bus with remote I/O (such as S800 modules).
In distributed control systems (DCS), complex logic control and process automation applications, the PM866AK01 3BSE076939R1 module is responsible for program execution, real-time data processing, communication with the I/O subsystem, and connection to the upper-level system. This module is suitable for medium and large industrial control systems and is particularly suitable for scenarios with high requirements for real-time performance, reliability and scalability.
The PM866AK01 can be configured, programmed and debugged online through the ABB 800xA system (Automation System 800xA) or the Control Builder M tool. Through these platforms, IEC 61131-3 standard control programs, including languages such as LD, FBD, and ST, can be designed and downloaded, and system-level integration and monitoring can be carried out.

02
Ethernet interface
2 × RJ45 Ethernet ports (CN1, CN2), used for connecting to the control network
Supports ABB control network protocols such as MMS and IAC
Suitable for establishing data exchange levels with other control units, HMI/SCADA systems.
03
Serial interface
2× RS-232C serial ports (COM3, COM4)
COM3: Standard RS-232C serial port (with modem control signal)
COM4: Isolated serial port (for configuration tool connection, debugging)
Helpful for connecting and debugging terminals, old equipment or communication devices.
04
I/O Expansion and CEX Bus
Supports up to 96 I/O modules (in single machine mode)
Supports up to 84 I/O modules (in redundant mode)
Total module bus scanning period: 0 - 100 ms (depending on the number of modules)
The Modulebus scanning rate depends on the number of I/Os and the configuration.
Introduction to Redundant Functions
CPU redundancy:
The controller supports CPU redundancy, which means that two CPU modules can work simultaneously to achieve higher availability. If the main CPU fails, the backup CPU can immediately take over the control task to ensure the continuous operation of the system.
CEX-Bus redundancy: The controller's CEX-Bus (an internal communication bus) also supports redundant configuration to ensure the reliability of the controller's internal communication.
Communication interface redundancy: The baseboard of the PM866AK01 controller has two RJ45 Ethernet ports (CN1, CN2) for connecting to the control network and supports redundant configuration. In this way, even if one communication interface fails, the other interface can still maintain a network connection.
S800 I/O redundancy: The controller supports redundant configuration of S800 I/O modules to ensure the reliability of I/O data and the continuous operation of the system
Built-in redundant Ethernet communication port:
The controller has a built-in redundant Ethernet communication port, which further enhances the communication reliability of the system
Through these redundant configurations, the ABB PM866AK01 controller can provide high availability and fault tolerance, and is suitable for industrial automation systems with high reliability requirements.
Installation, configuration and operation
Installation
Install the PM866AK01 module onto the DIN rail and arrange it neatly with other modules (such as communication and power modules);
Connect the CEX bus and other control networks through the base.
Ensure a stable power connection for the module.
Configuration
Load the program using ABB engineering software (such as 800xA Control Builder);
Configure the network settings (IP address) and task cycle.
Download the control program and variable allocation.
Operation
After powering on, observe the LED to check the CPU status.
Use the monitoring software to view real-time data and manage alarms.
Save the operation history to optimize the control strategy.
