Product Introduction

The ABB PM860K01 3BSE018110R1 is a CPU module for the ABB AC 800M process control system. It runs control logic, manages I/O through ModuleBus, and communicates with engineering stations and other controllers via dual Ethernet ports.The PM860K01 sits in the mid-range of the AC 800M CPU family, using an MPC860 processor with 8 MB RAM. It supports CEX communication modules and local S800 I/O expansion. Because AC 800M CPUs share similar front panels but differ in memory, firmware, and redundancy capability, the exact suffix and part number must be confirmed before replacement.

Installation & Configuration Guide

Preparation (10 min)

  • Photograph the existing CPU label, slot position, Ethernet cabling, and Flash card.
  • Record the firmware version and application name from the engineering station.
  • Back up the AC 800M application before removing the CPU.
  • Verify the 24 VDC supply is within 19.2–30 VDC.

Removal (5–10 min)

  • Confirm whether the controller is redundant. Do not remove the active primary CPU without approval.
  • Label Ethernet, serial, and ModuleBus connections.
  • Remove the Flash memory card only after confirming a valid backup exists.
  • Release the DIN-rail locking mechanism and withdraw the module.

Installation (10 min)

  • Install the replacement in the same slot position.
  • Insert the Flash card only if it matches the existing application revision.
  • Reconnect Ethernet and serial cables exactly as labeled.
  • Verify ModuleBus terminators and adjacent modules are seated.

Power-On & Test (10 min)

  • Apply 24 VDC and check CPU LEDs for normal run status.
  • Confirm the CPU enters RUN mode without fault indication.
  • Verify Ethernet communication with the engineering station.
  • Check I/O status through the configured AC 800M application.
  • Document firmware version, Flash card ID, and LED status.

 

Troubleshooting Quick Reference

Symptom Most Likely Cause Fast Check
No LEDs lit No 24 VDC supply Measure supply at CPU terminals
CPU in STOP Application or hardware fault Read diagnostic message in engineering tool
Ethernet link down Wrong cable or switch port Check RJ45 link LED and IP settings
Flash card error Missing or corrupted card Reseat card; verify application backup
I/O not updating ModuleBus fault Check terminators and adjacent modules
Redundancy fail Primary/secondary mismatch Compare firmware and configuration
Serial port not responding Wrong COM settings Verify baud rate and cable pinout

Dimensions, Mounting & Wiring Notes

  • Mounting: DIN-rail mounted AC 800M CPU module.
  • Dimensions: Exact H×W×D not confirmed for this part number. Verify against the current ABB AC 800M mechanical drawing.
  • Power: 24 VDC through the module power connector. Maintain 19.2–30 VDC.
  • Ethernet: Two RJ45 ports for control network and engineering access.
  • Serial: Two RS232 ports for programming, debugging, or point-to-point communication.
  • Flash Card: Handle as a static-sensitive component. Do not remove during active write operations.

 

FAQ

What is the ABB PM860K01 3BSE018110R1?
It is an AC 800M CPU module. The PM860K01 provides MPC860-based processing with 8 MB RAM for process control applications.Is it the same as 3BSE018100R1?
Not necessarily. Both part numbers are associated with PM860K01 in the field, but suffix and revision differences can affect firmware, memory, or certification. Always confirm against the physical nameplate.Can I use it in a redundant AC 800M system?
Only if the system was originally configured for PM860K01 redundancy and the replacement matches the existing firmware. Redundant pairs must be compatible.I replaced the CPU and the application will not download. What should I check?
Check the firmware version, Flash card status, and Ethernet IP settings. Also confirm the engineering station software supports this CPU revision.Does it support S800 I/O?
Yes. The AC 800M CPU connects to S800 I/O through the ModuleBus interface.What power supply does it need?
24 VDC, typically around 180 mA for the PM860 class CPU. Allow additional margin for communication and I/O modules.Can you test it before shipping?
Function can be verified under test conditions: power-up, LED status, Ethernet communication, serial port response, and Flash card recognition. Full application testing requires access to the original AC 800M configuration.
