The module employs a dual-core processor designed for stable, high-performance industrial computing. Although specific storage parameters vary among distributors, mainstream specifications indicate the presence of dedicated RAM with battery-backup and ECC (Error Correction Code), ensuring data integrity and secure retention during power interruptions.

A CompactFlash interface allows program loading via CF card or Ethernet. Some sources specify configurations of 2 GB RAM and 4 GB Flash, providing sufficient capacity to support large and complex control applications.

High Redundancy and Functional Safety

The controller supports full-system redundancy, including CPU, CEX bus, communication interfaces, and S800 I/O. Ethernet ports can operate in redundant mode, with switchover times under 10 ms, preventing unexpected system shutdowns.

When combined with applicable safety modules, the controller can form a 1oo2D architecture, is TÜV-certified, and meets SIL3 requirements according to IEC 61508, making it suitable for high-risk safety applications such as emergency shutdown (ESD) systems.

Efficient Task Processing

The system supports up to 16 tasks, with a minimum task cycle of 1 ms and event sequencing resolution below 1 ms. This ensures rapid execution of control commands, fast response to process changes, and efficient handling of complex logic and advanced process control functions.

Scalability and Communication Capability

The controller can be expanded with up to 12 fieldbus communication modules, supporting a wide range of industrial protocols including PROFIBUS-DP, Foundation Fieldbus, and Modbus.

Local I/O can be connected through electrical or optical Modulebus, supporting up to 8 local stations.

Remote I/O via PROFIBUS-DP supports up to 98 stations, with maximum cable lengths of 500 m (copper) or 2 km (multimode fiber).

CEX-bus segmentation can be extended using BC810/BC820 modules to support larger system architectures.

Application Scenarios

With high reliability and safety certification, this module is widely deployed in oil & gas, petrochemical, power generation, metallurgical, papermaking, and pharmaceutical industries. It integrates seamlessly with ABB systems, including IRB1400/IRB1600 robots, and connects efficiently with drives, sensors, and other automation equipment, enabling sophisticated process control and large-scale data acquisition.
