Product Introduction
ABB CI860K01 3BSE032444R1 is a communication interface module that connects AC 800M controllers to external fieldbus networks. It serves as a gateway for integrating third-party PLCs, supervisory systems, or legacy equipment without re-architecting the existing I/O infrastructure.This module supports multiple industrial protocols including Modbus TCP, PROFINET IO, PROFIBUS DP-V1, Ethernet/IP, DeviceNet, and ControlNet. Field deployments show it reduces integration time significantly when connecting packaged systems to plant SCADA. Always verify protocol support and firmware version against your specific controller configuration before procurement.
Installation & Configuration Guide
Preparation (10 min)
Verify the module matches your system configuration exactly. Check firmware version compatibility with your AC 800M controller. Ensure you have the correct TB850 terminal base. Confirm the controller is in maintenance mode.Removal (5–10 min)
Place the controller in maintenance mode. Disconnect the network cable from the front port. Release the module from the TB850 base using the locking mechanism. Inspect the CEX-bus connector pins for damage. (I once saw a technician bend a CEX-bus pin by forcing the module at an angle — always align straight before pushing.)Installation (10 min)
Align the new module with the TB850 base. Push firmly until the locking mechanism engages. Reconnect the network cable. Verify the module seats flush with adjacent modules. Check that status LEDs illuminate correctly.Power-On & Test (10 min)
Exit maintenance mode and observe the module status LEDs. Verify communication handshake with the controller using the engineering tool. Test fieldbus connectivity by reading/writing test values. Confirm redundancy status if applicable.
Troubleshooting Quick Reference
| Symptom | Probable Cause | Action |
|---|---|---|
| No LED illumination | CEX-bus connection fault | Reseat module; inspect TB850 base pins |
| Communication failure | Protocol mismatch | Verify protocol configuration in engineering tool |
| Intermittent drops | Network cable or termination | Check cable integrity; verify termination resistors |
| Red fault LED | Firmware incompatibility | Update controller firmware or replace module |
| Redundancy loss | Second module fault | Check second CI860K01; verify redundancy configuration |
Dimensions, Mounting & Wiring Notes
- Dimensions: 127.5mm (L) x 185mm (H) x 59mm (W)
- Mounting: DIN-rail via TB850 terminal base
- Wiring: Front-access RJ45 connector for fieldbus; CEX-bus connection via backplane
- Note: Always photograph DIP switch positions and cable routing before removal. Ensure adequate ventilation space above and below the module.
FAQ
Will this module work with my AC 800M controller?
It depends on your controller firmware version. CI860K01 requires specific firmware support in the AC 800M CPU. Send us your controller model and firmware version, and we’ll confirm compatibility before you order.I replaced the module but it won’t communicate. What now?
First, verify the protocol configuration matches your network setup. Check that the IP address (for Ethernet-based protocols) doesn’t conflict. Confirm the TB850 base is properly seated. We’ve seen cases where the base wasn’t fully locked, causing intermittent CEX-bus failures.Is this module new or refurbished?
This unit is refurbished and fully tested under simulated operating conditions. It is not factory-sealed new surplus. Function is verified; cosmetic wear may be present.Can I use this for both primary and redundant networks?
Yes. The CI860K01 supports redundant configurations. You can install up to 12 modules per AC 800M controller, each connecting to the same or separate fieldbus subnets. Verify redundancy is enabled in your engineering tool configuration.What’s the lead time if you don’t have it in stock?
Typically 3–5 business days for tested units. If you need a specific firmware revision that’s backordered, we’ll tell you upfront rather than ship something incompatible.Do you include a test report?
Yes. Every unit ships with a test record showing communication verification across supported protocols. No report, no shipment.I’ve never configured a fieldbus gateway before. Any tips?
Start with a simple Modbus TCP connection to verify basic communication before attempting complex protocols. Document your IP addressing scheme. And always back up your controller configuration before making changes — recovery is painful without a backup.
