Product Details

1SAP121000R0001 PM564-RP Product Description

The ABB PM564-RP (1SAP121000R0001) is a compact, high-performance CPU module engineered for deployment within the ABB AC500 programmable logic controller platform. Designed to serve as the computational core of distributed and centralized control architectures, the PM564-RP delivers deterministic scan-cycle execution, robust communication capability, and seamless integration across all AC500 system layers — from field-level I/O to supervisory SCADA and HMI environments. Its architecture-ready design ensures consistent signal flow, modular scalability, and long-term maintainability across demanding industrial applications.

Within a complete automation architecture, the PM564-RP occupies the control layer, coordinating logic execution, data acquisition, and inter-module communication. It interfaces directly with AC500 expansion I/O modules such as the DC532 digital input/output module and the AX522 analog I/O module, enabling precise process variable monitoring and actuator control. The CPU's onboard communication ports support Modbus RTU/TCP, CANopen, and CS31 bus protocols, allowing contextual integration with field devices, drives, and remote I/O stations without additional gateway hardware in standard configurations.

Power integrity is maintained through the AC500 PS501 power supply module, which provides regulated 24 VDC to the CPU and I/O backplane. The PM564-RP mounts directly onto the TB521 terminal base, which serves as the mechanical and electrical backbone of the rack assembly. This modular backplane architecture allows engineers to expand the system incrementally — adding communication modules such as the CM572-DP PROFIBUS DP master or CM589-PNIO PROFINET I/O controller — without redesigning the base control cabinet layout.

For operator interface, the PM564-RP integrates with ABB's CP600 HMI panel series via Ethernet or serial links, enabling real-time visualization of process states, alarm management, and parameter adjustment at the machine or plant level. In applications requiring motion coordination, the CPU can communicate with ABB ACS series variable frequency drives over Modbus TCP or CANopen, supporting speed reference, torque feedback, and fault diagnostics within a unified control loop.

Signal isolation and conditioning are addressed through the use of AC500 signal isolator modules and external DIN-rail-mounted isolators where field wiring introduces ground loops or noise. The PM564-RP's deterministic execution engine ensures that isolated analog signals are processed within defined scan-cycle tolerances, maintaining measurement accuracy across temperature-variable industrial environments.

Redundancy and fault tolerance are achievable within the AC500 platform by pairing the PM564-RP with a redundant CPU configuration using a second PM564-RP unit and the appropriate redundancy synchronization module, enabling bumpless switchover in critical process applications such as power generation, water treatment, and petrochemical continuous processes. This architecture eliminates single points of failure at the control layer while preserving the same I/O and communication infrastructure.

Diagnostic capability is a core strength of the PM564-RP. The module provides onboard LED status indicators for CPU run/stop state, communication activity, and fault conditions. Combined with ABB's Automation Builder engineering software, engineers can perform online monitoring, variable forcing, program upload/download, and structured fault logging — reducing commissioning time and enabling rapid root-cause analysis during maintenance cycles. The CPU supports IEC 61131-3 programming languages including Ladder Diagram, Function Block Diagram, Structured Text, Instruction List, and Sequential Function Chart, providing flexibility across engineering disciplines.

Each PM564-RP unit supplied by NANKMOS is sourced from verified distribution channels, pre-shipment tested against ABB factory specifications, and covered by a 12-Month Warranty. In-stock availability ensures minimal lead time for MRO procurement, system expansion, and emergency replacement scenarios. Units are packaged in anti-static, moisture-resistant materials suitable for international logistics.

The PM564-RP functions as the architectural anchor of a complete AC500-based automation platform. A fully integrated system typically includes the following components operating in coordinated layers:

This layered architecture ensures that the PM564-RP operates within a fully validated, contextually integrated control environment — maximizing system uptime, diagnostic transparency, and long-term maintainability.

The ABB PM564-RP is deployed across a broad range of industrial sectors where deterministic control, modular scalability, and communication flexibility are essential:

Q1: Is the PM564-RP compatible with existing AC500 V2 and V3 system configurations? The PM564-RP is designed for the AC500 platform and is compatible with AC500 V2 terminal bases, I/O modules, and communication modules. Engineers should verify firmware version alignment using ABB Automation Builder prior to integration into existing racks. NANKMOS technical support can assist with compatibility confirmation for specific system configurations.

Q2: Can the PM564-RP be used in a redundant CPU architecture for continuous process applications? Yes. The AC500 platform supports CPU redundancy configurations using paired PM564-RP units with synchronization modules. This architecture provides bumpless switchover at the control layer, ensuring process continuity in power generation, petrochemical, and water treatment applications where unplanned downtime is not acceptable. NANKMOS supplies matched redundant pairs with coordinated pre-shipment testing.

Q3: What is the warranty and lead time for the PM564-RP from NANKMOS? All PM564-RP units supplied by NANKMOS are covered by a 12-Month Warranty from the date of shipment. Units are held in stock and are pre-shipment tested against ABB factory specifications before dispatch. Standard lead time for in-stock units is 3–7 business days for international shipments.
