Description

ABB PM585 Processor Module

Product Overview

The ABB PM585 (standard catalog model PM585-ETH, order code 1SAP140500R0271, with an Extreme Condition variant PM585-ETH-XC) is a high-performance CPU processor module for the ABB AC500 modular programmable logic controller (PLC) platform.

Equipped with a 400 MHz 32-bit processor, 1 MB of program memory, onboard Ethernet, and dual serial ports, it is designed for complex automation tasks requiring fast cycle times, multi-protocol networking, and scalable local or distributed I/O.

Key Advantages

• High-Speed Processing: With a 400 MHz clock speed and nanosecond-level bit/floating-point execution (0.004 µs / 0.008 µs), it easily handles complex mathematical algorithms, PID loops, and high-speed machine control.
• Rich Onboard Connectivity: Built-in Ethernet (supporting Modbus TCP, TCP/IP, UDP, and integrated Web Server) alongside two configurable RS-232/485 ports reduces the need for extra communication couplers in mid-to-large systems.
• Flexible Modular Architecture: Plugs onto AC500 terminal bases (TB511-ETH, TB521-ETH, or TB541-ETH) allowing you to snap on up to 4 additional fieldbus modules (PROFINET, PROFIBUS DP, EtherCAT, CANopen, etc.) on the left and up to 10 S500 I/O modules on the right.
• On-Device Diagnostics: Features a built-in LCD screen and status LEDs that display IP addresses, error codes, and diagnostic messages directly on the module without needing a laptop connected.
• Harsh Environment Option (-XC): Available in an Extreme Condition (PM585-ETH-XC) version featuring conformal-coated PCBs and extended temperature/vibration tolerance for outdoor or corrosive environments.

Important Installation & Usage Precautions

• Terminal Base Required: The PM585 is a processor module only and cannot operate standalone. It must be mounted onto an compatible AC500 terminal base (such as TB511-ETH, TB521-ETH, or TB541-ETH), which provides the 24 V DC power terminals and backplane bus.
• No Hot-Swapping of CPU or Communication Modules: Always switch off the 24 V DC power supply before plugging or unplugging the PM585 processor or left-side communication couplers on the terminal base to avoid hardware damage.
• Backup Battery Installation: Verify that the backup lithium battery (TA521) is properly installed and activated before commissioning to retain retentive variables and the Real-Time Clock (RTC) during power outages.
• SD Card Formatting: Use ABB-approved industrial SD cards formatted in FAT16/FAT32. Do not remove the SD card while the CPU is actively writing logs or booting firmware.
• Enclosure & Airflow: Rated IP20. Mount horizontally on a 35 mm DIN rail inside a grounded industrial cabinet, leaving adequate top and bottom clearance for natural convection cooling.

Applications

• Infrastructure & Water Treatment: Pump stations, desalination plants, and wastewater treatment systems utilizing onboard Ethernet, Modbus, and IEC 60870-5-104 telecontrol protocols.
• OEM Machinery & Packaging: High-speed packaging lines, printing presses, and textile machines requiring fast cycle times and multi-axis motion coordination via EtherCAT or CANopen.
• Energy & Power Generation: Solar farms, wind turbine pitch/yaw control, and substation automation (especially with the -XC extreme condition variant).
• Building & Tunnel Automation: HVAC central plants, tunnel ventilation, and lighting control leveraging the built-in web server and serial/Ethernet interfaces.
