Description
ABB CI840A 3BSE041882R1
The ABB CI840A 3BSE041882R1 is a communication interface module for the ABB AC 800M controller, specifically designed for industrial automation systems to enable high-speed data interaction between the controller and field devices. Its core function is to support the PROFINET communication protocol, acting as a Master or Slave to connect various intelligent devices (such as distributed I/O, variable frequency drives, sensors, etc.), making it suitable for real-time communication and collaborative control in distributed control systems (DCS) and smart manufacturing scenarios.
- Operation Modes:
- Master Mode: Connects to distributed I/O devices (e.g., ABB PM500/PM800 series) and third-party PROFINET slaves (e.g., Siemens ET200SP, Phoenix Contact I/O, etc.).
- Slave Mode: Integrates with higher-level control systems (e.g., PLCs, DCS) to transmit data as a sub-device.
- Protocol Features: Supports PROFINET IO V1, compatible with standard messages, real-time (RT) communication, and isochronous real-time (IRT) functions (hardware-dependent), meeting high-precision synchronization requirements (e.g., motion control, robot collaboration).
- Transmission Rate: Fixed at 100 Mbps (full-duplex), supporting high-speed transmission of large data volumes (e.g., video streams, complex motion commands).
- Data Capacity: Supports a maximum of 1440 bytes input/1440 bytes output, suitable for high-density I/O or extremely real-time scenarios (e.g., automotive production lines, high-speed packaging machinery).
- Redundancy Mechanisms:
- Supports PROFINET Media Redundancy (MRP) and Device Redundancy (PRP), enabling the construction of highly reliable systems with redundant power supplies and controllers.
- Dual-port Ethernet interfaces (RJ45) support ring network topologies, with fault switching time < 200 ms.
- Plug-and-Play: Directly inserts into the AC 800M controller's backplane bus, auto-recognized by ABB Control Builder M software without additional drivers.
- Cross-Vendor Compatibility: Supports importing GSDML files of third-party devices, enabling seamless integration of PROFINET devices from brands like Siemens and Rockwell.
- Distributed Expansion: As a master station, a single module can connect up to 128 PROFINET slaves, supporting hierarchical network architectures (e.g., factory layer - workshop layer - device layer).
- Environmental Adaptability:
- Operating temperature: -20°C ~ +60°C, storage temperature: -40°C ~ +85°C.
- Vibration-resistant (compliant with IEC 60068-2-6) and electromagnetic interference-resistant (compliant with EN 61000 standards), suitable for harsh environments in metallurgy, chemicals, etc.
- Protection Level: IP20 (suitable for installation in control cabinets), supporting rail or backplane mounting.
- LED Status Indicators:
- PWR (Green): Steady on indicates normal power supply; off indicates a power failure.
- RUN (Green): Flashing indicates normal module operation; steady on or off indicates an abnormality (requires checking firmware or configuration).
- LINK/ACT (Yellow): Two lights indicate network connection status (steady on) and data transmission activity (flashing), respectively.
- ERROR (Red): Steady on indicates module faults, slave communication interruptions, or parameter errors.
- Online Hot-Swap: Supports live module replacement (requires a redundant system configuration or ensuring non-operation status).
