Product Introduction
ABB CI871AK01 3BSE092693R1 is a PROFINET IO communication interface module for the AC 800M and 800xA control systems. It bridges the controller and field devices over standard Ethernet networks.This module supports up to 256 I/O devices and includes a built-in web server for configuration and diagnostics. Field technicians should verify the DIP switch settings on the front panel before commissioning, as incorrect addressing is a common startup issue.
Installation & Configuration Guide
Preparation (10 min)
Review the CI871AK01 hardware manual. Verify the PROFINET device name and IP address match your network plan. Prepare CAT6 shielded Ethernet cable. Ensure the AC 800M rack is powered down.Removal (5–10 min)
Disconnect the RJ45 Ethernet cable. Release the module locking lever. Slide the module out of the CEX bus slot. Inspect the backplane connector for bent pins or debris.Installation (10 min)
Set the DIP switches to the correct PROFINET address before insertion. Align the module with the CEX bus guide rails. Slide in firmly and engage the locking lever. Connect the shielded Ethernet cable to the RJ45 port.Power-On & Test (10 min)
Power up the rack. Check the LED indicators on the module front panel. Access the built-in web server via the configured IP address. Verify that all connected PROFINET IO devices are online and exchanging data.
Troubleshooting Quick Reference
| Symptom | Probable Cause | Action |
|---|---|---|
| Module Not Detected | CEX Bus Connection | Reseat module; inspect backplane pins |
| PROFINET Devices Offline | IP/Name Mismatch | Verify DIP switches and device name in controller |
| Intermittent Comm Loss | Bad Ethernet Cable | Replace with shielded CAT6; check bend radius |
| Red Error LED Lit | Firmware or Config Fault | Check web server diagnostics; verify firmware version |
| Web Server Unreachable | Wrong Subnet | Ping module; verify PC is on same subnet |

FAQ
Is this module PROFIBUS or PROFINET?
This specific model (CI871AK01) is a PROFINET IO interface. If you need PROFIBUS DP, you are looking for a different module (like the CI854 series). Always verify the exact ordering code.How do I find the module’s IP address?
Use the built-in web server. Connect a laptop to the same network segment and browse to the module’s default or configured IP. The web interface shows all PROFINET device statuses.Can I hot-swap this module?
The AC 800M system supports hot-swapping for many modules, but always check your specific system configuration and redundancy settings before pulling a live module. Power down if unsure.Why won’t my PROFINET devices come online?
90% of the time it is a device name mismatch. PROFINET uses device names, not just IP addresses. Verify the device name in the controller configuration matches the physical device exactly.Do you provide a test report?
Yes. Every refurbished CI871AK01 is tested on an AC 800M rack with actual PROFINET IO devices. The test report documents communication verification and LED status.What firmware version does this unit have?
We document the exact firmware revision on the test report. If your system requires a specific version, let us know before ordering and we will match it.I lost the DIP switch manual. Where do I find it?
Contact us or ABB support for the CI871AK01 hardware manual. The DIP switch table maps binary positions to PROFINET station addresses. Do not guess — wrong settings will prevent communication.
