DSCS131 57310001-LM

Exclusive MasterFieldbus Bus Master Gateway
As the core interface of the AC410/AC450 main control for external expansion of fieldbus, it carries ABB’s dedicated MasterFieldbus deterministic real-time bus, realizing low latency data exchange between the main control and remote I/O sub racks, field subsystems, and ensuring stable closed-loop control timing.
MXB backplane high-speed interoperability
By bidirectional transmission of massive process data through the DSBB110A/DSBB175 backplane MXB bus and controller, the CPU bus computing load is shared without occupying the main control logic scanning resources.
Dual link redundant communication architecture
Supports dual redundant bus channels for electrical/optical fibers, automatically switches without disturbance in case of single link disconnection or cable failure, and does not interrupt the production control circuit throughout the process, adapting to the high reliability requirements of power plants and key chemical equipment.
Long distance signal shaping relay
Integrated signal amplification and synchronous regeneration circuit, coupled with fiber optic interface, greatly extends the bus communication distance, solves the problem of signal attenuation and distortion in long-distance cables, and supports distributed multi-point I/O networking in the factory area.
Full channel electrical isolation+EMC anti-interference
Bus port independent isolation filtering circuit, eliminates frequency converter, high voltage equipment EMI RF interference, ground loop potential difference, avoids communication garbled code and data loss, and is suitable for harsh industrial sites.
Real time bus self diagnostic alarm
Continuously inspect bus disconnection, short circuit, communication timeout, and verification errors; The panel LED status lights visually distinguish between operation/faults, and the fault codes are uploaded to the main control in real time to quickly locate network anomalies.
