ABB 3BHE037864R0107

Detailed Technical Specifications

1. Processing Power & Core Architecture

CPU Type: Powerful 32-bit RISC processor.

Clock Speed: 700 MHz (significantly more powerful than the older PM861 counterpart).

Memory:

RAM (User Program & Data): 128 MB SDRAM.

Flash Memory (for OS and Firmware): 32 MB.

Performance: Designed for complex and demanding control applications with high I/O count and fast execution requirements.

2. Physical & Environmental Specifications

Form Factor: A single-width module designed for installation in an AC 800M Controller Unit (e.g., CI861, CI862, CI863, CI865).

Dimensions (H x W x D): Approx. 130 mm x 55 mm x 117 mm (without connectors).

Weight: Approx. 0.3 kg.

Operating Temperature: 0°C to +60°C (32°F to 140°F).

Storage Temperature: -40°C to +70°C (-40°F to 158°F).

Relative Humidity: 5% to 95% (non-condensing).

Protection Rating: IP20 (must be installed in a protective cabinet).

3. Electrical Specifications

Power Supply: The PM864A itself is powered by the backplane of its parent Controller Unit (e.g., CI861). It does not have a separate power connection.

Backplane Power Consumption: Typically 7.5 W (max 9 W).

4. Communication & Interfaces

The PM864A's communication capabilities are provided by pairing it with various Communication Interface (CI) modules. The controller itself has connectors on its front for these modules.

On-board Ports:

Ethernet Port: 1 x 10/100 Mbit/s port for engineering station connection (used for configuration and programming via Control Builder M).

Serial Port (COM): 1 x RS-232C port for service and maintenance purposes.

Expansion via CIs: To communicate with I/O, networks, and other devices, it requires Communication Interface modules like:

CI861: Provides two channels for S800 I/O (Profibus DP).

CI862: Provides PROFINET I/O Controller and Ethernet/IP Scanner functionality.

CI863: Provides redundant Ethernet for peer-to-peer communication.

CI865: Provides redundant PROFIBUS DP Master connectivity.

5. Software & Programming

Engineering Tool: Control Builder M (Professional edition is required for full configuration).

Programming Languages: Fully supports all IEC 61131-3 languages:

Function Block Diagram (FBD)

Ladder Diagram (LD)

Structured Text (ST)

Instruction List (IL)

Sequential Function Chart (SFC)

Firmware: The controller runs a real-time operating system. The firmware version must be compatible with the version of Control Builder M and the System 800xA extension versions being used.

6. Key Features

High Availability: Supports redundant (hot standby) configuration when paired with a second PM864A controller and appropriate communication modules (e.g., CI863). This allows for bumpless switchover in case of a primary controller failure.

Extensive I/O Support: Can manage a large number of distributed I/Os (S800 I/O, S900 I/O, etc.) via various fieldbuses.

Integration: The central brain of an 800xA node, enabling seamless integration of control, safety, electrical, and information management within a single operator station view.

Cybersecurity: Features like role-based access control, audit trails, and support for network security protocols to meet modern industrial security standards.
