ABB DSPC172H 57310001-MP | Processor Unit

Description

The ABB DSPC172H, order number 57310001-MP, is a processor unit for ABB Advant OCS control systems. It belongs to the MasterPiece processor-module family and is categorized for the central units of MasterPiece 200 and MasterPiece 200/1 controllers. Its documented hardware designation specifies a CPU unit without static read/write memory, an important distinction when identifying the correct processor assembly for an existing controller configuration.

The DSPC172H has net dimensions of 350 × 250 × 47 mm and a net weight of 0.9 kg. These values support physical identification and equipment-handling planning. For replacement selection, the complete model designation and order number should be matched against the installed hardware and the applicable controller documentation. Similar processor-module designations should not be treated as proof of interchangeability.

Key Technical Specifications

Detailed Product Overview

Processor Unit and Control-System Role

The ABB DSPC172H is a processor unit associated with ABB’s Advant OCS and MasterPiece control-system architecture. Its product classification places it among the processor modules used in the central units of MasterPiece 200 and MasterPiece 200/1 controllers.

The processor unit forms part of the controller hardware rather than a field-level input or output module. This distinction is important during maintenance planning because processor hardware and I/O hardware serve different functions within an automation system. Correct identification must begin with the installed controller and its documented hardware configuration.

Hardware Designation and Memory Considerations

A defining characteristic in the product description is that the DSPC172H is a CPU unit without static read/write memory. This designation should be retained when comparing the unit with other processor boards or preparing a replacement-parts list.

The absence of static read/write memory in the stated unit description does not, by itself, establish how memory is arranged across a particular controller assembly. Engineers should consult the applicable system documentation before making assumptions about memory modules, configuration data, program storage, or requirements for companion hardware.

Displays

In the single line diagram displays of the electrical network, the generators are only presented by the most important actual measured analogue data. Dedicated displays are available for more detailed generator information:

• Generator overview

In this display, is In table format, detailed generator data is presented in a table regarding the actual control mode of the governor and the AVR, working setpoint and some alarms. It also offers, thanks to its layout, an overview of available modes for each generator individually.

• Synchronization overview

In this display is the generator data included to complete and enable synchronization. It is not intended for mode- or setpoint control of the generator. For synchronization of the generator, this display can be consulted.

• Capability diagram

The P-Q diagram of the generator includes:

– dynamic working point tracking

– actual control mode, setpoint and working point

– related analogue data

• Object display

In this display very detailed information is presented regarding the actual control mode of the governor and the AVR, related analogue data, working setpoint and all alarms.
