CI590 3BSE013231R1 | ABB | S800 I/O AF100 Communication Interface

Product Overview

The ABB CI590 (3BHT340092R1) acts as a high-performance communication gateway within the S800 I/O system. This module links S800 I/O clusters to the Advant Fieldbus 100 (AF100), enabling seamless data exchange between Advant Controllers (such as AC 410, AC 450, or AC 160) and remote I/O stations. By managing the high-speed broadcast of process variables, the CI590 ensures that time-critical I/O data reaches the control logic with minimal jitter. We supply this unit as 100% Brand New and Original, maintaining factory-sealed integrity for mission-critical DCS environments.

Technical Specifications

• Current Consumption: Typ. 100 mA at 24 V

• Redundancy Support: Yes (when used in redundant pairs)

• Isolation: Galvanic isolation between bus and internal logic

• Diagnostic Indicators: Fault (F), Run (R), Warning (W), and Traffic LEDs

Engineering Advantages

• Deterministic Data Exchange: The CI590 utilizes the AF100 broadcast protocol to guarantee deterministic communication. This prevents data collisions on the network, ensuring that safety-interlock signals and PID control loops update at precise, repeatable intervals.

• Flexible Redundancy Options: The module supports redundant AF100 cable configurations. In high-availability setups, two CI590 modules work in tandem to provide a fail-safe communication path, protecting the process against single cable breaks or module hardware faults.

• Simplified Network Commissioning: Built-in address switches allow for rapid hardware-level station identification. This "physical-first" configuration reduces software overhead during commissioning and makes field replacements straightforward for maintenance technicians.

• Integrated Bus Supervision: The module continuously monitors the AF100 signal quality and station status. It triggers local LED indicators and system-level alarms the moment it detects a drop in communication integrity, allowing for proactive troubleshooting.

• Compact DIN Rail Integration: The CI590 snaps directly onto the Module Termination Unit (MTU), sharing the same mechanical profile as standard S800 I/O modules. This allows for a clean, unified cabinet layout without requiring external communication converters.

FAQs

• Can I use the CI590 with a PROFIBUS master?

  No. The CI590 is specifically designed for the Advant Fieldbus 100 (AF100) protocol. For PROFIBUS DP applications, you should select the CI801 or CI840 series modules.

• Does the CI590 support Hot Swap?

  Yes, if you install it on a compatible MTU that supports hot swapping, you can replace the module while the rest of the I/O station remains powered. However, always verify that the redundant partner is active before removing the module during live operations.

• What is the maximum number of I/O modules one CI590 can manage?

  A single CI590 can typically manage up to 12 I/O modules in its local cluster. For larger stations, you may need to extend the Modulebus using extension cables and additional clusters.

• How do I set the AF100 station address?

  The module features rotary or DIP switches (depending on the revision) on the side or front panel. You must set a unique address for each station on the AF100 network before powering up the unit.
