The ABB PM861AK01 3BSE018157R1 is a processor unit in the AC 800M control system.

1. Hardware Performance

Processor: Equipped with an MPC860 processor running at 48MHz, it executes 1,000 Boolean operations in 0.23 milliseconds, meeting data processing and computing needs in general industrial control.
Memory: Total memory is 16MB, including 7.155MB of application-accessible RAM and 2MB of flash memory for storing firmware, programs, data, and historical records.

2. Communication Interfaces

Ethernet Ports: Two RJ45 ports (CN1, CN2) connect to control networks, supporting Ethernet communication compliant with IEEE 802.3 standards for high-speed data exchange with other devices.
Serial Ports: Two RJ45 ports (COM3, COM4). COM3 is an RS232C port with modem control signals, and COM4 is isolated for connecting configuration tools.

3. Power Specifications

Supply Voltage: 24V DC (range: 19.2–30V DC).
Power Consumption: Typical 250mA (6.0W); maximum 430mA (10.3W). It supports redundant power status input and includes a 3.6V lithium battery for data retention during power outages.

4. Other Parameters

Real-time Clock: Stability of 100ppm (approx. 1 hour/year). CNCP protocol enables 1ms clock synchronization between AC 800M controllers.
Event Queue: Each OPC client can hold up to 3,000 events in the controller, with transmission speeds of 36–86 events/sec and 113–143 data messages/sec from AC 800M to OPC servers.
CEX Bus: Supports 12 communication modules with a maximum bus supply current of 2.4A.
Module Bus:

Non-redundant CPU: 1 electrical + 7 fiber optic I/O clusters.
Redundant CPU: 0 electrical + 7 fiber optic I/O clusters.
I/O capacity: 96 modules for single PM861A, 84 modules for redundant configuration. Scan rate: 0–100ms. Electrical bus supply current: up to 1.0A at 24V and 1.5A at 5V.

5. Functional Features

Redundancy Design: Supports redundancy for CPU, CEX bus, communication interfaces, and I/O modules to prevent single-point failures and ensure continuous operation during partial faults.
Flexible Programming: Supports IEC 61131-3 standard languages (LD, ST, FBD), allowing users to choose programming methods based on habits and project needs.
Easy Configuration: Configurable via 800xA Control Builder to enhance engineering efficiency.
Fault Diagnosis: Reliable and simple diagnostic programs quickly locate faults, reducing maintenance downtime.
High Stability: Industrial-grade design with strong EMC immunity, suitable for harsh environments. Protection class IP20 for indoor use.

6. Physical Characteristics

Dimensions: 189mm (H) × 135mm (W) × 119mm (D).
Weight: Approximately 1.15–1.2kg.

7. Application Scenarios

Industrial Automation: Controls production lines, packaging machines, printing equipment, etc., for precise process management.
Process Control: Suitable for fine control in petroleum, chemical, and pharmaceutical industries to ensure production stability and safety.
Power Systems: Applied in substation automation, grid dispatching, and energy management for efficient operation and reliable monitoring.
Building Industry: Used in intelligent building control systems for Building automation and security monitoring.
Other Fields: Applicable to marine, water treatment, rail transit, and other sectors.
