ABB CEX-Bus and AF 100 Communication Architecture

The CI869 provides the physical and logical interface between an AC 800M controller and the ABB Advant Fieldbus 100 network. The module integrates CEX-Bus communication logic, an AF 100 communication unit, and a DC/DC converter for internal voltage distribution.

The module receives +24 VDC input through the CEX-Bus and supplies the required operating voltage for the communication electronics. Additionally, the integrated twisted pair modem enables direct connection to AF 100 field devices and controller stations.

The CI869 supports redundant cable configurations and redundant communication interface arrangements. Therefore, an AC 800M controller equipped with CI869 operates as an AF 100 station that exchanges process data with other AF 100 nodes.

Backplane Bus Communication and Redundancy Functions

The CI869 uses ABB controller expansion architecture with CEX-Bus communication handling. The module supports communication interface redundancy and line redundancy configurations for continuous fieldbus operation.

Furthermore, the module supports hot swap operation, allowing replacement procedures within supported AC 800M configurations without complete system shutdown. The communication design maintains AF 100 slave station behavior while transferring data between connected control nodes.

The CI869 can also operate within AC 800M High Integrity systems where communication availability and controlled system behavior are required.

Frequently Asked Questions

Q: What communication protocol does the CI869 3BSE049110R1 support?
A: The CI869 supports ABB Advant Fieldbus 100 communication through twisted pair (TWP) connections with a transmission speed of 1.5 Mbit/s.

Q: Does the CI869 support redundant communication configurations?
A: Yes. The module supports both line redundancy and module redundancy functions when installed in compatible AC 800M configurations.

Q: How is the CI869 powered inside the AC 800M system?
A: The CI869 receives +24 VDC supply through the CEX-Bus and uses an internal DC/DC converter to generate required operating voltages.

Field Installation Guidelines

Install the CI869 module on the designated AC 800M CEX-Bus position according to the controller hardware configuration.

Verify that the twisted pair (TWP) fieldbus wiring follows ABB fieldbus installation requirements. Maintain proper cable routing separation from high-voltage power conductors and high-frequency interference sources.

Connect the communication shield according to the site grounding standard to minimize electrical noise coupling. Confirm that redundant fieldbus cables and redundant communication interfaces are installed according to the configured system topology.

Before commissioning, verify the +24 VDC supply connection, CEX-Bus communication status, and AF 100 network addressing parameters.
