ABB PM867K01 (3BSE076355R1) – High‑performance AC 800M CPU for System 800xA and S800 I/O

The ABB PM867K01 is a fast, reliable CPU unit for the AC 800M platform, typically used in System 800xA installations where determinism, redundancy options, and broad fieldbus connectivity really matter. From my experience, teams choose the PM867K01 when they need a stable controller at the core of a DCS, with room to scale field communications and I/O without reworking the architecture.

Key Features

• AC 800M Core CPU – Designed for ABB System 800xA, giving you tight integration with Control Builder M and ABB libraries.
• Fast task execution – Suits large logic programs and high I/O counts; you might notice smoother cycle times versus earlier PM86x units.
• Dual Ethernet 10/100 – Two RJ45 ports for plant/control networks, engineering access, and controller interconnects.
• CEX‑Bus expansion – Add fieldbus modules (e.g., PROFIBUS DP, Modbus) without changing the controller footprint.
• S800 I/O interoperability – No onboard I/O; uses proven S800 I/O via ModuleBus for distributed, hot‑swappable I/O.
• Redundancy ready – In many cases supports controller redundancy when paired with the appropriate ABB redundancy accessories.
• IEC 61131‑3 engineering – Ladder, Function Block, Structured Text, etc., through Control Builder tools many teams already know.

Application Fields

You’ll typically find the PM867K01 in medium‑to‑large DCS nodes where uptime counts:

• Oil & Gas (wellhead control, compressor stations, pipeline SCADA interfaces)
• Chemicals & Petrochem (batch/continuous units, utilities, flare and interlocks)
• Power Generation (boiler auxiliaries, BOP, balance‑of‑plant sequences)
• Pulp & Paper (machine sections, drives coordination, winder control)
• Metals & Mining (process lines, conveying, crushing/milling supervision)
• Marine & Terminals (cargo handling logic, loading arms, utility systems)

Advantages & Value

• Reliability that scales – Robust CPU with redundancy options for plants aiming at higher availability.
• Compatibility – Works within ABB 800xA and S800 I/O ecosystems, reducing integration risk and engineering hours.
• Lifecycle efficiency – Typically reuses existing I/O and networks, which seems to be the biggest cost saver in migrations.
• Serviceability – Clear diagnostics via Ethernet/service port; firmware and project backup on removable media keeps downtime short.

Customer feedback: “We swapped a legacy PM86x for PM867K01 during a weekend shutdown. Keeping the S800 I/O and fieldbus modules as-is saved us days of commissioning.”

Installation & Maintenance

• Cabinet & mounting – Install on DIN rail within a clean, ventilated control cabinet; leave room for airflow and service access.
• Power & grounding – Provide a regulated 24 V DC supply; bond shield and protective earth properly to minimize noise.
• Networks – Use industrial Ethernet switches; segregate control and plant networks when possible; label ports for engineering/service.
• I/O subsystem – Connect to S800 I/O via the appropriate ModuleBus/communication units; verify address ranges and termination.
• Firmware & project – Back up the CompactFlash/flash storage before upgrades; keep firmware levels aligned with 800xA node versions.
• Routine care – Periodically check connectors, clean dust with dry air, confirm battery/RTC status if used, and review diagnostics in Control Builder.
• Safety – De‑energize the cabinet before module exchange; observe ESD handling to protect the CPU and CEX modules.

Recommended Accessories & Compatible Modules

• ABB CI854A – PROFIBUS DP master for field device integration.
• ABB CI851/CI852 – Modbus RTU/TCP connectivity, often used for MCCs and drives.
• S800 I/O (e.g., AI810, AO810, DI810, DO810) – Flexible analog/digital I/O families with hot‑swap capability.
• Redundancy hardware – Appropriate ABB redundancy module and cabling, if you plan CPU redundancy.
• Industrial switches – Managed Ethernet switches with VLAN/QoS for deterministic control traffic.

Quality & Certifications

• CE compliant; typically UL listed for industrial control equipment
• RoHS conformity in most markets
• Manufactured under ISO 9001 quality systems
• Standard warranty: 365 days

If you’re replacing an existing AC 800M CPU or expanding an 800xA node, the ABB PM867K01 (3BSE076355R1) is a solid choice. One thing I appreciate is how it lets you grow fieldbus capacity via CEX modules without touching the controller footprint—saves time and wiring in real projects.
