ABB CI810B AF100 Field Communication Interface – Product Introduction

The ABB CI810B AF100 Field Communication Interface is a specialized communication module designed for connecting S800 I/O stations to control systems using the AF100 fieldbus network. As part of ABB’s highly modular and widely adopted S800 I/O family, the CI810B serves as the gateway that enables efficient, deterministic, and secure data exchange between distributed field devices and higher-level controllers such as the AC 800M. Its robust communication capabilities and industrial-grade construction make it an ideal choice for process automation applications that depend on stable and time-critical data transmission.

Reliable AF100 Fieldbus Connectivity

The CI810B is engineered to operate as a dedicated interface between the S800 I/O system and the AF100 fieldbus, ABB’s proven high-speed communication protocol for distributed automation. AF100 is known for its fast update cycles, strong determinism, and high reliability—qualities essential for applications where continuous process visibility and rapid response times are required.

With the CI810B, users can integrate S800 I/O modules into existing AF100 networks effortlessly. The interface communicates directly with the fieldbus master, transferring digital and analog process values, diagnostics, and control commands with high accuracy and minimal latency. This ensures consistent system behavior even in large or complex distributions of remote I/O stations.

Seamless Integration with S800 I/O

A key advantage of the CI810B is its tight integration with ABB’s S800 I/O system, which is widely used in process industries for its flexibility, compact size, and modular design. The interface supports a wide range of S800 modules, including analog inputs, analog outputs, digital I/O, and specialty modules such as pulse counters or temperature inputs.

The CI810B manages the communication mapping, channel updates, and synchronization needed for smooth interaction between the S800 modules and the AF100 network. Because configuration is handled through ABB’s engineering tools, the module simplifies commissioning and reduces engineering time.
