ABB CI810A 3BSE013262R1 AF100 Field Communication Interface Module

The ABB CI810A 3BSE013262R1 serves as the primary CI810A Field Communication Interface Module utilized to execute high-speed AF100 fieldbus traffic management across S800 I/O and Advant/800xA platforms. Equipped with an onboard 16 MHz processor, 0.5 MB FPROM, and 0.5 MB SRAM, the hardware coordinates deterministic data exchange between distributed I/O clusters and host controllers through two integrated AF100 modems with full media cable redundancy.

Hardware Specifications

Backplane Bus Communication Velocity & Media Redundancy

The CI810A interface engine links directly to the S800 I/O module bus structure, driving low-latency data polling across connected I/O stations while maintaining fixed cycle times. Dual onboard AF100 modems drive physical signal transmission over separate coaxial or twisted-pair physical channels. When operating in a cable-redundant configuration, the internal communication logic continuously evaluates signal integrity on both physical lines, instantly transferring active bus traffic to the secondary channel upon detecting physical link degradation or line disconnection without interrupting controller task execution.

Frequently Asked Questions

Q: How does cable redundancy operate across the dual AF100 modems on the CI810A?

A: Both integrated modems receive incoming network frames simultaneously, allowing the hardware to switch active data paths seamlessly at the packet layer if one cable experiences open-circuit or short-circuit failures.

Q: What mounting configurations support the physical housing of the CI810A module?

A: The physical housing installs directly onto standard DIN rails or inside S800 I/O cabinet module termination structures, engaging the backplane bus headers for power and internal signal distribution.

Q: Does the onboard memory require battery backup during system power outages?

A: System firmware and configuration parameters store permanently in the 0.5 MB non-volatile FPROM, while runtime data buffers utilize 0.5 MB SRAM refreshed continuously via the 24 VDC backplane supply.

Field Installation Guidelines

Mount the CI810A module vertically onto the mounting rail assembly inside an IP20 or higher enclosure, ensuring that top and bottom vents retain a minimum 50 mm clearance gap to allow natural air convection across the -25 deg C to +70 deg C operating window. Ground all AF100 network cable shields directly to the cabinet earth grounding bar using low-impedance grounding clamps located near the entry point to mitigate high-frequency electrical noise interference. Verify that both physical AF100 channel connectors seat completely onto the module modems before applying power. Route power wires away from communication lines to prevent electromagnetic coupling into the AF100 signal drivers.
