ABB CI867AK01 3BSE092689R1 AC 800M Communication Interface Package
Configured for Modbus TCP Ethernet protocol execution in System 800xA network architectures, the ABB CI867AK01 (CI867A Modbus TCP Communication Interface Package) provides direct physical/electrical execution. The assembly mounts on a CEX-Bus backplane via the TP867 baseplate to manage master and slave data messaging between an AC 800M controller and external Ethernet field networks.

CEX-Bus Communication Logic and Network Execution
The CI867A expansion unit houses CEX-Bus protocol logic, an integrated Ethernet communication processor, and an internal DC/DC converter. The converter draws primary power from the controller's +24 VDC CEX-Bus power rail to generate internal operating voltages. Operating over a single 10/100 Mbit/s RJ-45 Ethernet port, the interface module establishes Modbus TCP request-response framing across standard TCP/IP network infrastructures via an external Ethernet switch. The module supports hot-swappable installation, allowing online replacement without de-energizing adjacent modules on the backplane rail. Module redundancy ensures uninterrupted execution of client and server socket connections during primary module failover.
Frequently Asked Questions
Q: Can the CI867A module perform hot swap operations during system runtime?
A: Yes, the CI867A communication interface supports hot swapping on the TP867 baseplate. Removing the module does not disrupt the main CEX-Bus power rail or communication continuity to other backplane expansion units.
Q: How many Modbus TCP slave and master devices can a single CI867A interface manage?
A: A single CI867A interface handles connections to a maximum of 70 Modbus TCP slave units and up to 8 Modbus TCP master units simultaneously.
Q: What software version is required to run the CI867A interface?
A: The CI867A hardware module requires ABB System 800xA version 6.0.3.3, 6.1.1, or subsequent software versions along with matching Compact Control Builder software.
Field Installation Guidelines
- Baseplate Mounting: Secure the TP867 baseplate directly to the DIN rail and engage the CEX-Bus side connector before locking the mechanical latches. Align the physical keying mechanism to verify baseplate engagement.
- Module Insertion: Align the CI867A module guide pins with the TP867 baseplate connector. Press firmly until the latch mechanisms lock completely onto the baseplate rail.
- Network Cabling: Connect a shielded CAT5e or CAT6 Ethernet cable with an 8-pin RJ-45 connector to the Ethernet port. Ensure the cable shield terminates to the cabinet functional earth rail through low-impedance grounding clamps.
- Bus Termination and Power Verification: Verify that the CEX-Bus layout does not exceed 12 total communication units per controller. Ensure system supply voltage stays within standard +24 VDC limits before energizing the cabinet.
