ABB CI627 3BSE009799R1 AF100 Communication Interface

The ABB CI627 3BSE009799R1, also cataloged as the CI627 AF100 Communication Interface Unit, operates as a dedicated hardware component for high-speed bus coupling and network signal transmission within Advant Master Process Control System platforms.

Hardware Specifications

Backplane Bus & Communication Determinism

The ABB CI627 3BSE009799R1 acts as an Advant Fieldbus 100 (AF100) interface node engineered to deliver deterministic cyclic data exchange across industrial controller networks. The module executes high-velocity backplane bus communication protocols that maintain low transmission latencies between controller subracks and remote I/O stations. Internal firmware flash compatibility ensures continuous network synchronization and prevents packet loss across high-density Advant system topologies.

Frequently Asked Questions

Q: Can the AF100 twisted pair connectors on the CI627 be wired or disconnected while the network is active?

A: While disconnecting a channel physically interrupts AF100 bus traffic on that specific segment, the dual-channel configuration of AF100 networks allows redundant bus channels to sustain controller communication without dropping system node status.

Q: What is the primary function of the CI627 module in an Advant controller rack?

A: The module functions as a physical buscoupler that translates backplane communication data into differential signals suited for twisted pair AF100 fieldbus distribution.

Field Installation Guidelines

1. Insert the CI627 module vertically into the dedicated subrack slot until backplane connectors seat completely.
2. Secure top and bottom panel mounting screws to establish chassis frame grounding and mechanical stability under operational vibration.
3. Terminate AF100 twisted pair wiring using the included dedicated connectors, maintaining proper signal polarity (+/-) across all bus nodes.
4. Verify that bus termination resistors (150 ohm) are installed at both physical ends of the AF100 cable trunk line.
