Product Details

DSPC171 57310001-CC Product Description

The ABB DSPC171 57310001-CC is a high-performance central processing unit engineered for deployment within ABB's AC 800M Distributed Control System platform. Designed to serve as the computational core of a modular DCS architecture, this processor module delivers deterministic scan-cycle execution, robust inter-module communication, and seamless integration across the full AC 800M hardware ecosystem. Whether deployed in greenfield process plants or as a replacement unit in an existing control cabinet, the DSPC171 57310001-CC provides the processing backbone required for reliable, scalable, and maintainable industrial automation.

The module operates within ABB's S800 I/O and AC 800M controller family, coordinating signal acquisition, logic execution, and data exchange across layered control architectures. Its architecture supports redundant CPU configurations, enabling uninterrupted process control in critical applications such as power generation, oil and gas processing, chemical manufacturing, and water treatment. The DSPC171 57310001-CC is fully compatible with ABB's Control Builder M engineering environment, simplifying commissioning, diagnostics, and long-term firmware management.

The DSPC171 57310001-CC functions as the central orchestration node within a multi-layer AC 800M control architecture. At the control layer, it executes IEC 61131-3 function block programs and structured text logic, coordinating with redundant CPU partners such as the PM860 / PM861 processor modules to maintain hot-standby failover capability. The CPU communicates with the TB820 ModuleBus modem and TB840 redundancy module mounted on the same backplane, ensuring deterministic data exchange between the controller and distributed I/O clusters.

At the I/O layer, the DSPC171 57310001-CC interfaces with ABB S800 I/O modules including the AI810 analog input module, AO810 analog output module, DI810 digital input module, and DO810 digital output module, all mounted on CI810 or CI830 communication interface units. These I/O modules provide the signal acquisition and actuation pathways for field instruments, transmitters, and final control elements across the process plant.

At the communication layer, the processor supports PROFIBUS DP master functionality via the CI854 PROFIBUS DP interface module, enabling integration with variable frequency drives, intelligent motor control centers, and remote I/O stations. For plant-wide data exchange, the module connects to ABB System 800xA via the SC510 communication module, supporting OPC DA/UA data publishing to historian and SCADA layers. The CI860 IEC 61850 communication interface extends the architecture into substation automation and power management domains.

At the power layer, the AC 800M rack is supplied by the SD821 / SD822 power supply unit, which provides regulated 24 VDC to the backplane and all installed modules. Redundant power supply configurations using dual SD822 units eliminate single-point power failures in high-availability installations. At the HMI layer, the DSPC171 57310001-CC integrates with ABB's PP865 / PP886 operator panel series, delivering real-time process visualization and alarm management directly from the controller's data model.

Power Generation: In thermal and hydroelectric power plants, the DSPC171 57310001-CC manages turbine governor logic, boiler combustion control, and generator excitation sequencing within a redundant AC 800M architecture. Its hot-standby CPU capability ensures zero-downtime switchover during planned maintenance or unexpected faults.

Oil & Gas Processing: Deployed in upstream wellhead control panels and downstream refinery units, the module executes safety-critical shutdown logic in coordination with ABB's Safety Manager SC platform. Its PROFIBUS DP master capability connects to smart valve positioners and pressure transmitters distributed across hazardous-area junction boxes.

Chemical & Petrochemical: In continuous process plants, the DSPC171 57310001-CC handles multi-loop PID control for reactor temperature, pressure, and flow, with scan cycles optimized for tight process tolerances. Integration with System 800xA enables advanced process control (APC) overlays and real-time optimization.

Water & Wastewater Treatment: Municipal water authorities deploy the AC 800M platform for SCADA-integrated pump station control, chemical dosing, and filtration sequencing. The DSPC171 57310001-CC's Ethernet connectivity supports remote monitoring and alarm notification across geographically distributed treatment facilities.

Mining & Minerals Processing: In ore processing and conveyor control applications, the module coordinates crusher sequencing, belt weigher integration, and flotation cell control. Its robust operating temperature range and modular I/O expansion support the demanding electrical environments of mining control rooms.

Q1: Is the DSPC171 57310001-CC compatible with existing AC 800M racks and backplanes? Yes. The DSPC171 57310001-CC is designed for direct installation into standard AC 800M controller racks using the TB820 ModuleBus modem and TB840 redundancy backplane. No rack modification is required. The module is recognized automatically by ABB Control Builder M upon insertion, and firmware version alignment with the existing project can be managed through the engineering tool's download function.

Q2: Can this CPU module be configured for hot-standby redundancy without additional hardware? Hot-standby redundancy requires a second DSPC171 57310001-CC unit installed in the redundant CPU slot of the same rack, along with the TB840 redundancy module. The redundancy link is established automatically through the backplane, and switchover time is typically less than one scan cycle. Both CPUs must run identical firmware versions and project configurations to maintain synchronization.

Q3: What warranty and supply assurance does NANKMOS provide for the DSPC171 57310001-CC? NANKMOS provides a 12-Month Warranty on all DSPC171 57310001-CC units, covering manufacturing defects and functional failures under normal operating conditions. Each unit undergoes pre-shipment functional testing to verify communication interfaces, backplane connectivity, and firmware integrity.
