ABB CI860K01 Fieldbus Modules

The ABB 3BSE032444R1 (Model: CI860K01) is a high-performance communication interface kit designed for the 800xA automation platform. It serves as the physical and logical bridge between the System 800xA controller backplane and High-Speed Ethernet (HSE) networks, allowing direct, deterministic integration of FOUNDATION Fieldbus instruments and field devices into the distributed control system architecture.

Hardware Specifications

Process Control Instrumentation and DCS Communication

The CI860K01 module implements an optimized processing matrix to maintain high data transmission velocity across industrial network topologies. When parsing complex telemetry packets from intelligent field devices—such as multivariable pressure transmitters, digital valve positioners, or instrumentation managing critical variables via the 4-20 mA HART loop protocol—the module routes the digital data straight through its embedded High-Speed Ethernet protocol stack.

Frequently Asked Questions

Q: What is the mechanical function of the included TP860 baseplate during system installation?

A: The TP860 baseplate functions as the physical mounting foundation and structural path for the controller's Communication Expansion (CEX) bus. It mounts directly onto a standard DIN rail, allowing the active CI860 module to slide on and plug in securely. This design enables the CEX-bus signals and 24 VDC power lines to feed continuously through adjacent baseplate segments without manual wiring blocks.

Q: How does the 100/1000 Mbps auto-negotiation speed affect existing legacy 100 Mbps field switches?

A: The module's RJ-45 physical transceiver contains an integrated hardware autosensing switch matrix. When connected to an older 100 Mbps network segment, the CI860 automatically matches its baud rate to the lower speed. This ensures broad backward compatibility with existing legacy networking hardware while eliminating the risk of packet collisions or synchronization failures on the link.
