Specifications

Description

The DSPC171 57310001-CC is a high-performance Processor Unit in the ABB Advant Master/MasterPiece 200/1 system. It is an upgraded version of the DSPC155 and is responsible for core system computation, I/O scheduling, and communication management. It is the control core of older DCS systems.

Applications

Oil refineries: Used to manage distributed process control logic for large refining units.

Coal power plants: Control key power systems such as boiler feedwater and turbine auxiliary systems.

Steel and iron smelters: Provide real-time logic scheduling and safety interlocking functions in automated production lines.

Paper machinery plants: Execute precise speed chain control and paper moisture content control (QCS) algorithms.

Large fertilizer plants: Achieve highly reliable closed-loop control in high-pressure reaction processes such as ammonia synthesis.

Competitive Advantage

Core Control Operations: Executes DCS control programs, performs logic operations, and processes real-time data, offering superior performance compared to the DSPC155.

System Bus Management: Schedules the MasterPiece 200/1 local bus, coordinating I/O, communication, and storage modules.

Program and Data Storage: Built-in program and configuration storage, supporting program upload/download and system backup.

Multi-Protocol Communication: Manages internal and external communication within the system, enabling data interaction with host computers, PLCs, and third-party devices.

Status Monitoring and Diagnostics: Onboard LED indicators display real-time running, fault, and communication status, supporting fault diagnosis.

Compatibility Upgrade: Compared to the DSPC155, it improves processing speed, storage capacity, and system stability.

Interface and Installation

Installation Location: Dedicated CPU slot in the MasterPiece 200/1 controller rack

Installation Method: Eurocard, direct plug-and-play

Connection: Interconnects with DSMB series I/O modules, DSMC series storage modules, and DSCS series communication modules via local bus

Compatibility: Fully compatible with the DSPC155 hardware interface; can be directly replaced without modifying system configuration.

FAQ

Q: What is the DSPC171 57310001-CC?
A: It is a Processor Unit.

Q: Does the DSPC171 57310001-CC support hot standby redundancy?
A: Yes. In the Advant architecture, two CPUs typically work together to achieve dual-machine hot standby, ensuring uninterrupted operation in case of a single point of failure.

Q: Do I need to manually set the station number after replacing the DSPC171 57310001-CC CPU?
A: No. The station number is usually physically defined by the rack mount or configured by software; it will be automatically inherited when the board is replaced.

Q: Does the DSPC171 57310001-CC support Ethernet connection?
A: No. It requires a communication module or a dedicated gateway to interact with modern Ethernet.

Q: How do I back up the internal programs of the DSPC171 57310001-CC?
A: You need to use engineering station software to upload backups via serial port or communication bus.
