Description
ABB CI855-1 3BSE018134R1
I. Product Overview
The ABB CI855-1 3BSE018134R1 is a communication interface module belonging to the ABB System 800xA distributed control system series, and serves as a key supporting component for the AC 800M controller. Its core positioning is to act as a communication bridge between the control system, field devices and heterogeneous subsystems. Through multi-protocol compatibility and redundant communication design, it achieves efficient data interaction and collaborative control across devices and systems, providing stable and reliable communication guarantee for process control, intelligent manufacturing, energy management and other fields.
II. Functional Features
- Comprehensive Multi-protocol Compatibility for Seamless Heterogeneous System IntegrationBuilt-in rich protocol processing units, it fully supports mainstream industrial communication protocols such as Modbus, PROFIBUS, CANopen, Profinet and EtherCAT, enabling seamless connection with field devices (frequency converters, intelligent instruments, sensors) of different communication standards and heterogeneous control systems. Without the need to configure additional dedicated protocol conversion devices, two-way cross-protocol data transmission can be realized, which greatly improves the compatibility and flexibility of system communication and reduces the difficulty of heterogeneous system integration.
- Redundant Communication Design for Uninterrupted Link ReliabilityEquipped with two Ethernet RJ45 ports, it supports network redundancy function and can build a dual-link redundant communication architecture. When the main communication link fails, the system can automatically switch to the standby link to ensure uninterrupted data transmission, greatly improving the reliability and stability of the communication link. Meanwhile, it has a clock synchronization function to ensure the consistency of data transmission timing among multiple devices and systems, avoiding control coordination failures caused by timing deviations.
- Hot-swappable Function for Convenient Maintenance and UpgradingSupporting hot-swappable operation, the module can be directly installed and removed without stopping the system, which greatly reduces the system downtime during maintenance and upgrading and improves operation and maintenance efficiency. Combined with the modular design, it is convenient for technicians to quickly replace faulty modules or expand communication interfaces, ensuring the continuity of industrial production.
- Full-link Diagnosis for Accurate Fault Early WarningIt has comprehensive communication link status monitoring and intelligent fault diagnosis functions, which can real-time monitor protocol interaction status, data transmission quality (packet loss rate, bit error rate), network connection status and the module's own operating status (power supply, circuit working status). When faults such as communication interruption, protocol mismatch, data transmission error and power supply abnormality are detected, the alarm mechanism is triggered immediately. The fault type is intuitively fed back through the status indicator light, and the fault log (including fault type, occurrence time and relevant communication parameters) is automatically recorded and uploaded to the upper control system, providing accurate basis for operation and maintenance personnel to quickly locate and handle faults.
- Industrial-grade Reliable Protection with Strong Environmental AdaptabilityAdopting an industrial-grade high-strength shell design, it has excellent dustproof and impact resistance performance, which can effectively resist dust erosion and slight mechanical collision in industrial sites. The product supports a wide operating temperature range and can run stably in harsh temperature and humidity environments. It strictly complies with industrial electromagnetic compatibility standards, with built-in EMI filter circuits and multi-layer shielding protection layers, which can effectively resist strong electromagnetic interference generated by frequency converters, high-voltage equipment, etc., ensuring communication stability in complex electromagnetic environments.
- Convenient Integration and Operation & Maintenance with Excellent AdaptabilityIt realizes fast connection with the AC 800M controller through the backplane TP853 and CEX-Bus, and the modular design simplifies the system integration process. Adopting standardized DIN rail mounting, it has a compact size and saves installation space in the control cabinet. Equipped with clear interface identification and status indicator lights, it is convenient for on-site technicians to quickly complete wiring, debugging and operation status inspection. It supports online parameter configuration and firmware upgrading, and maintenance operations can be completed without disassembling the module, reducing operation and maintenance difficulty and time cost.

IV. Working Principle
The core working logic of the ABB CI855-1 3BSE018134R1 communication interface module is "protocol identification and adaptation → data parsing and conversion → redundant link transmission → status monitoring and feedback → fault alarm and isolation". Through the coordination with the AC 800M controller, field devices and heterogeneous systems, it completes cross-device and cross-system communication coordination tasks. The specific working process is as follows:
Protocol Identification and Adaptation: The module establishes a connection with the AC 800M controller through CEX-Bus, and at the same time accesses field devices or heterogeneous systems through Ethernet ports. It automatically identifies key parameters such as the communication protocol type and transmission rate of the connected devices/systems, completes the initialization matching of communication protocols, and ensures compatible connection with devices of different communication standards.
Data Parsing and Conversion: For heterogeneous data of different protocols, the built-in protocol processing unit of the module parses the received data packets in real time to extract core control commands, status parameters and other information; at the same time, according to the protocol type of the target device/system, it converts the parsed data into a format recognizable by the target protocol, realizing two-way cross-protocol data conversion and intercommunication.
Redundant Link Transmission: The converted standardized data is transmitted to the target device/system through the dual Ethernet redundant links. The module real-time monitors the operating status of the two links. When the main link fails, it immediately switches to the standby link automatically to ensure uninterrupted data transmission; at the same time, it calibrates the transmission timing among multiple devices through the clock synchronization function to ensure the synchronization and accuracy of data transmission.
Status Monitoring and Feedback: During operation, the module real-time monitors protocol interaction status, data transmission quality, network connection status, its own power supply operating status and communication status with the controller, builds a full-link status monitoring network, and comprehensively grasps the operating status of the communication link.
- Fault Alarm and Isolation: When working conditions such as communication interruption, protocol mismatch, data transmission error, power supply abnormality and link failure are detected, the alarm mechanism is triggered immediately. The fault type is intuitively fed back through the status indicator light, and the fault log is automatically recorded and uploaded to the upper control system; at the same time, it can execute fault isolation measures according to preset strategies to avoid fault spread affecting the operation of the entire communication network, providing accurate basis for operation and maintenance personnel to quickly locate and handle faults.
