ABB CI840A 3BSE041882R1 | Redundant PROFIBUS DP-V1 Interface for S800 I/O

Description

1. Product Overview

The ABB CI840A (3BSE041882R1) is a high-availability Fieldbus Communication Interface (FCI) for the S800 I/O system. It provides a robust gateway between a PROFIBUS DP-V1 master and the S800 I/O modules via the ModuleBus.

The “A” designation signifies the latest hardware revision, offering enhanced diagnostic capabilities and improved stability. The CI840A is uniquely capable of operating in a redundant configuration (when mounted on a redundant termination unit like the TU840). This ensures that if one communication link or module fails, the secondary module takes over bumplessly, preventing process interruption and expensive downtime.

Key Applications:

• Critical Process Control: High-reliability communication for oil refineries, gas processing, and chemical plants.
• Fault-Tolerant Architectures: Essential for systems requiring Triple Modular Redundancy (TMR) or dual-redundant PROFIBUS networks.
• Smart Device Management: Utilizing PROFIBUS DP-V1 acyclic services for remote instrument configuration and HART data pass-through.
• Large-Scale I/O Integration: Managing high-density I/O clusters (up to 12 modules) in complex automation networks.

7. FAQ

Q: Can I use CI840A to replace an old CI840?

Yes, the CI840A is the direct functional replacement for the legacy CI840. It is designed to be backward compatible, though it is often recommended to update your GSD files in the engineering tool to utilize all the “A” version’s features.

Q: Do I need two CI840A modules for redundancy?

Yes. To achieve module redundancy, you must have two CI840A units mounted on a redundant termination unit (like the TU840). They work in a primary/backup mode.

Q: Does this module support HART communication?

The CI840A itself facilitates the PROFIBUS DP-V1 “pipe.” To use HART, you must pair it with S800 I/O modules that specifically support HART (like the AI845 or AO845).
