ABB CI854K01 Profibus-DP/V1 Interface Kit

Configured for high-speed fieldbus communication in ABB AC 800M controller networks, the ABB CI854K01 (CI854K01 Profibus-DP/V1 Interface Kit) provides direct physical/electrical execution.

Hardware Specifications

Backplane Bus Communication & Profinet / EtherNet/IP Deterministic Networks

The ABB CI854K01 interface module links the AC 800M processor to field networks via the CEX-Bus backplane, maintaining deterministic cyclic data exchange across industrial communication loops. Utilizing Master Class 1 and Class 2 DP-V0/DP-V1 protocols at baud rates up to 12 Mbit/s, the module coordinates high-density I/O polling and acyclic parameter transfers to remote nodes, motor starters, and drives. Built-in galvanic isolation decouples the fieldbus physical layer from backplane bus communication velocity limits and internal processor electronics, shielding controller backplane traffic from noise transients and field ground loops.

Frequently Asked Questions

Q: What power source supplies the CI854K01 module during active communication?

A: The module draws power directly from the 24 VDC supply rail routed across the CEX-Bus backplane, consuming 190 mA under typical operation (240 mA maximum) without requiring an external terminal power feed.

Q: Can the CI854K01 be replaced without powering down the AC 800M controller rack?

A: Yes. The CI854 communication module supports hot swapping on the TP854 baseplate, enabling online module replacement without interrupting power or communication across adjacent modules on the CEX-Bus.

Q: What physical connectors are provided for PROFIBUS network wiring?

A: The module interface package incorporates two female DB9 connectors on the TP854 baseplate, allowing direct attachment of standard 9-pin PROFIBUS field bus plugs for line pass-through or redundant segment connections.

Field Installation Guidelines

Mount the TP854 baseplate firmly onto a standard 35 mm DIN rail inside an IP20-rated protective cabinet enclosure. Align the CI854 module card connectors with the baseplate guide pins and slide the unit until the backplane bus interface latches seat completely. Route PROFIBUS cable shields directly to the cabinet ground bus bar using low-impedance grounding clamps, ensuring full 360-degree shielding contact. Maintain physical separation between PROFIBUS trunk cables and high-voltage AC motor lines to eliminate inductive coupling. Verify that line termination resistors are activated at the two physical endpoints of every PROFIBUS segment before applying network power.
