ABB CI810B 3BSE020520R1 AF 100 Fieldbus Communication

Product core positioning

ABB CI810B 3BSE020520R1 AF 100 is a high-performance fieldbus communication module designed for data exchange between devices in industrial automation scenarios. Its core function is to serve as a "data bridge" between field devices (such as sensors, actuators, frequency converters) and upper control systems (such as DCS, PLC), enabling efficient and stable communication between different devices and systems. It also supports multiple industrial bus protocol conversions and data integration, and is a key component in mainstream control systems such as ABB 800xA to ensure smooth data flow at the field and control levels. It is widely applicable to scenarios such as process industries and discrete manufacturing that require high real-time and reliability communication.

Key technical parameters

1. Communication protocol and interface characteristics

Supporting protocols: The core supports PROFIBUS DP-V1/V2 protocol, and is compatible with FF H1 (Foundation fieldbus) and Modbus RTU/TCP protocol, enabling unified access and data exchange of multi protocol devices;

Communication interface: equipped with 2 PROFIBUS DP interfaces (RS-485 physical layer) and 1 Ethernet interface (10/100Mbps, supporting TCP/IP), the interface adopts anti loosening industrial grade connectors to ensure connection stability in long-term vibration environments;

Communication speed: The PROFIBUS DP interface speed can be adjusted (9.6kbps-12Mbps), and the Ethernet interface speed supports adaptation to meet the transmission needs of different distances and data volumes (short distance high-speed transmission or long-distance low-speed stable transmission);

Node capacity: A single module can connect up to 127 PROFIBUS DP slave devices, supporting hot plugging and online configuration of slave devices for easy system expansion and maintenance.

2. Data processing and performance

Data throughput: The maximum data transmission rate can reach 1.5MB/s (under PROFIBUS DP protocol), and the Ethernet interface has a unidirectional data throughput of ≥ 80Mbps, which can meet the needs of multiple devices simultaneously transmitting massive real-time data;

Response delay: The cyclic data transmission delay under the PROFIBUS DP protocol is ≤ 1ms, and the non cyclic data transmission delay is ≤ 10ms, ensuring real-time interaction between control instructions and on-site status data, and avoiding control deviations caused by communication delays;

Data Cache: Built in 512KB data cache area, which can temporarily store critical data during sudden data or network fluctuations, prevent data loss, and improve communication stability.

Can resist interference such as electrostatic discharge (± 8kV contact discharge, ± 15kV air discharge), radio frequency electromagnetic field radiation (10V/m), etc., ensuring uninterrupted communication signals

Physical dimensions

140mm x 100mm x 220mm (length x width x height)

Adopting ABB standard rail installation design, compatible with 35mm DIN rail, saving control cabinet space

4. Security and authentication

Having SIL 2 safety certification (compliant with IEC 61508 standard), it can be used for communication links of safety related control systems (such as emergency stop systems, safety interlock systems) to ensure operational safety in industrial scenarios;

Through CE certification, UL certification, ATEX explosion-proof certification (optional explosion-proof version), it can be used compliantly in the European Union, North America, and explosion-proof environments (such as chemical explosion-proof workshops, oil and gas field sites).

Core performance advantages

Multi protocol compatibility and flexible adaptation: Breaking down the "communication barriers" of different brands and protocol devices, without the need to add additional protocol conversion modules, it can achieve unified access of devices such as PROFIBUS, FF H1, Modbus, etc., reducing system complexity and hardware costs; Support online configuration of protocol parameters (via ABB Control Builder M software), enabling modification of key parameters such as communication rate and slave address without power outage, improving debugging and maintenance efficiency.

High reliability and redundancy design: using industrial grade components and reinforced circuit design, after 1000 hours of high and low temperature cycle testing (-25 ℃ to+60 ℃) and 500 hours of vibration testing (10-500Hz, acceleration 2g), the mean time between failures (MTBF) is ≥ 150000 hours; Support communication link redundancy (such as dual PROFIBUS DP interface backup) and power redundancy. When the main link or power supply fails, it can automatically switch to the backup link/power supply with a switching time of ≤ 100ms to ensure uninterrupted communication.

Real time and deterministic communication: The PROFIBUS DP-V2 protocol supports equal time synchronization mode (IRT), which can achieve microsecond level time synchronization of multiple slave devices, meeting high-precision collaborative control scenarios (such as synchronous motion of multi axis robotic arms and speed synchronization of multi device pipelines); By using priority data scheduling algorithms, key data such as control instructions and emergency signals are set to high priority and transmitted first to avoid real-time performance degradation caused by non critical data occupying bandwidth.

Usability and diagnostic capability: The Control Builder M programming and configuration software, which is compatible with the ABB 800xA system, provides an intuitive graphical configuration interface, supports automatic scanning and parameter import of slave devices, and simplifies the system construction process; Built in comprehensive fault diagnosis function, which can monitor the status of communication links in real time (such as interface faults, offline slave stations, data verification errors), and synchronize the fault location and cause feedback with the upper system alarm information through LED indicator lights (such as power lights, communication status lights, fault lights), shortening the fault troubleshooting time (average troubleshooting time ≤ 30 minutes).
