Advantages and Features
- Dual Redundant Ports for Uninterrupted Communication
The ABB CI858 3BSE018135R1 is equipped with two RJ45 ports that support ring topology redundancy, ensuring continuous data transmission even if one port or cable fails. This feature is critical for industries like oil and gas and power generation, where network downtime can lead to substantial operational losses.
- Multi-Protocol Flexibility for Heterogeneous Networks
Supporting a broad range of industrial Ethernet protocols, the ABB CI858 3BSE018135R1 eliminates the need for multiple specialized communication modules. It seamlessly integrates with ABB’s native systems and third-party devices from Siemens, Allen-Bradley, and others, reducing system complexity and total cost of ownership.
- High-Speed Low-Latency Data Transfer
With 100 Mbps full-duplex capability, the ABB CI858 3BSE018135R1 delivers fast, low-latency data exchange for real-time process control and large-volume data acquisition. Its optimized firmware minimizes communication delays, ensuring precise synchronization between controllers and field devices in time-sensitive applications such as batch processing and motion control.
- Rugged Design & Hot-Swap Capability
Built with industrial-grade components, the ABB CI858 3BSE018135R1 withstands extreme temperatures, humidity, and electromagnetic interference. It supports hot swapping, allowing maintenance teams to replace the module without powering down the controller, thus minimizing production downtime and improving plant availability.
Application Cases in Application Fields
- Oil and Gas (Onshore Refineries)
In a large onshore oil refinery, the ABB CI858 3BSE018135R1 connects AC 800XA controllers to pipeline flow meters, distillation tower temperature sensors, and emergency shutdown systems. Its redundant ports ensure communication continuity during cable maintenance, while its multi-protocol support enables integration with third-party safety instrumented systems (SIS) to meet strict industry compliance standards.
- Pharmaceutical Manufacturing
A pharmaceutical plant uses the ABB CI858 3BSE018135R1 to link its DCS with sterile filling machines, temperature-controlled storage units, and batch tracking software. The module’s low-latency data transfer ensures precise control of critical process parameters, helping the facility comply with FDA and GMP regulations for product traceability and quality assurance.
- Renewable Energy (Wind Farms)
In a utility-scale wind farm, the ABB CI858 3BSE018135R1 facilitates communication between turbine control systems and the central SCADA platform. Its rugged design withstands the variable temperature and vibration conditions of wind turbine nacelles, while its redundant ports prevent communication loss during severe weather events, maximizing turbine uptime.

Selection Suggestions and Precautions
Selection Suggestions
- Choose the ABB CI858 3BSE018135R1 for projects requiring redundant Ethernet connectivity and multi-protocol integration, especially in mission-critical applications with zero-downtime requirements.
- Verify compatibility with your existing ABB DCS firmware version; for Freelance DCS, ensure firmware is updated to v9.0 or later.
- Prioritize this module for outdoor or harsh environment deployments, thanks to its wide operating temperature range and robust anti-interference design.
Precautions
- Configure the dual ports for ring topology redundancy according to ABB’s official guidelines to maximize the ABB CI858 3BSE018135R1’s reliability in critical systems.
- Use shielded industrial Ethernet cables and proper grounding to minimize electromagnetic interference and ensure stable data transmission.
- Avoid mixing different Ethernet speeds in the same redundant ring, as this may cause communication conflicts and data loss.
- Perform regular firmware updates via ABB Control Builder M software to unlock new protocol features and enhance system security.
