Description
Product Introduction
⚙️ Product: CI627A
🏷️ Part Number: 3BSE017457R1
🔧 Brand: ABB
📡 Product Type: AF100 Communication Interface
The ABB CI627A 3BSE017457R1 is an AF100 Communication Interface used in ABB industrial automation systems. ABB identifies 3BSE017457R1 with the CI627A type designation and describes it as a CI627A AF100 Communication Interface.
🔌 The module provides communication connectivity within compatible ABB control architectures. It is associated with ABB AC 800M / Advant OCS environments and can be used for interfacing control-system components with field-level or distributed automation equipment. Available technical references identify a 9-pin D-sub RS-485 interface and Profibus DP-V0/V1 functionality for this CI627A variant.
🏭 This module is suitable for industrial process control, distributed I/O, drives, instrumentation, and legacy ABB automation-system maintenance. When replacing an existing unit, match the complete part number and hardware configuration rather than relying only on the CI627A designation.

Installation & Use
🛠️ Before installation, verify the complete CI627A 3BSE017457R1 identification, controller/backplane compatibility, firmware requirements, and communication configuration.
🔌 Connect the communication cable using the correct 9-pin D-sub interface and verify RS-485 wiring, shielding, termination, and network topology.
💻 Configure the PROFIBUS communication parameters according to the existing control-system project. Confirm station addresses, baud rate, master/slave configuration, and I/O data mapping.
📊 After startup, check the module diagnostics and communication status. Verify that all connected PROFIBUS devices are detected and that cyclic data exchange is operating correctly.
⚠️ Compatibility note: ABB’s official product identification describes 3BSE017457R1 as CI627A AF100 Communication Interface. Some third-party listings describe this variant with PROFIBUS DP functionality, so the exact installed system configuration should be checked before using the module as a replacement.
