ABB PM564-RP-ETH – Compact AC500-eCo CPU with Integrated Ethernet for Machine and Process Control

The ABB PM564-RP-ETH is a practical choice when you want a compact PLC CPU with built‑in Ethernet and relay outputs. It sits in the AC500‑eCo family, so you get straightforward engineering with ABB Automation Builder (CoDeSys‑based) and a form factor that fits tight panels. From my experience, this model suits small to mid‑size machines—packaging stations, HVAC skids, material handling cells, and dosing/mixing units—where you need reliable digital I/O, simple networking, and predictable cycle times without overcomplicating the cabinet.

One thing I appreciate is the -RP variant’s relay outputs, which typically let you drive actuators directly in many cases, reducing the need for extra interposing relays. You might notice that the -ETH suffix gives you a standard RJ45 port for programming and SCADA/HMI integration over Ethernet—helpful for OEMs standardizing on Modbus TCP or basic IP networking.

Key Features

• Integrated Ethernet (RJ45): Typically 10/100Base‑T for programming, HMI/SCADA connectivity, and Modbus TCP in many cases.
• Onboard digital I/O with relay outputs (RP): Suits direct switching of typical loads without additional interposing relays.
• 24 VDC supply: Common industrial power standard makes cabinet design straightforward.
• Serial communication port: In most deployments, supports Modbus RTU/ASCII via RS‑485/RS‑232 (model dependent).
• CoDeSys‑based engineering: Program with ABB Automation Builder using IEC 61131‑3 languages—helps shorten commissioning time.
• Compact DIN-rail housing: Fits typical control cabinets; neat for multi‑axis stations or skid‑mounted equipment.
• Scalable with ABB I/O: Expand digital/analog I/O using compatible modules as your machine grows.

Installation & Maintenance

• Panel environment: Install on EN 60715 DIN rail in an IP20 cabinet; allow top/bottom clearance for airflow. Avoid heat sources and excessive vibration.
• Power & grounding: Use a clean 24 VDC supply with proper over‑current protection; bond the PLC 0V to panel ground as per ABB guidelines.
• Wiring: Separate signal and power cabling; keep Ethernet and serial lines away from high‑frequency drives. Use ferrules and labeled terminals for serviceability.
• Networking: For Modbus TCP, assign a fixed IP and document addressing in the project files. Shielded CAT5e/CAT6 is recommended in noisy environments.
• Routine care: Periodically clean ventilation slots, check terminal tightness, and back up the project to Automation Builder. Firmware updates can be planned during scheduled downtime.
• Commissioning tip: From my experience, validating relay output contact ratings against field loads prevents nuisance failures and extends life.

Quality & Certifications

• CE compliant; typically cULus listed for industrial control equipment
• RoHS compliant materials
• Manufactured under ISO 9001 quality management
• Warranty: 365 days (exchange/repair terms apply)

If you’re standardizing on AC500‑eCo, the PM564-RP-ETH seems to be a sweet spot—Ethernet on board, relay outputs for direct switching, and simple expansion when needed.
