abb Triguard SC300E 3BNP004720R101 TMR Safety Products

Triguard SC300E

The ABB Triguard SC300E is the

evolution of 20 years of combined

vendor and customer experience

integrated into the design of the

ultimate TMR product. Building on a

proven platform, the Triguard SC300E

combines features that will maintain

excellence well into the future.

Today ABB is a global supplier with

key operating bases in North America,

Europe, Middle East and Asia Pacific.

The Company has successfully

supplied TMR products and systems to

meet an ever increasing diverse range

of applications, including:

• Safety Shutdown

• Electrical Stability and Load Control

• Process Shutdown

• Reactor Control

• Emergency Shutdown

• Critical Batch Processing

• Sequence and Interlock Control

• Fire & Gas Protection and Detection

• Critical Process Control

• Burner Management and Control

• Turbine and Compressor Control

• Wellhead/Sub-Sea Control

• Unmanned Installations

• FPSOs

P r o d u c t F a m i l y

The ABB Triguard SC300E TMR product family gives unrivalled performance in areas of reliability, availability, test coverage,

diagnostics and simplicity of operation. Advances in technology and improved production methods add cost benefits that

give significant price/performance advantages.

• Fewer unscheduled stoppages

highest availability, fault tolerant electronics with transient immunity and 3–2–0 or 3–2–1–0 voting

• Security for plant, product and people

fail-safe operation at all levels provides plant, product and personnel with the highest security

• Quality data

sequence of event and extensive diagnostics keep the operator informed

Highest Availability

The Triguard SC300E achieves the

highest possible TMR availability

(99.999%) by maximising the

Mean Time To Failure (MTTF) and

decreasing the Mean Time To Repair

(MTTR).

Modern low power integrated

technology allows the TMR

architecture to be cost effective for

an increasing range of high integrity

applications.

Simple to Use, Operate

and Maintain

The Triguard SC300E TMR product

functions as a single set of hardware

and software. The three processors

and triplicated I/O circuitry are

transparent to the user. Purchasing a

Triguard SC300E system will provide:

• Lowest Life Cycle Cost

• The Maximum Safety and

Availability

• The Highest Level of Safety and

On-Line Maintenance

Fail Safe Operation

Failure modes of the processors,

input/output circuitry, control program

and watchdog timer circuits are

managed so that circuits will default to

a predetermined safe state.

Highest Speed of Response

By using advanced processor

technology, whilst maintaining the

stability of the original core software,

Triguard SC300E delivers an

unrivalled scan time resolution

of 10ms.

High speed of response benefits the

customer application which specifies

Sequence of Events recording (SoE)

without the cost of additional

equipment. It also enables TMR to be

used for applications requiring high

speed advanced control.

Fault Tolerant Hardware and

Software

The system is designed to continue to

operate correctly with the presence of

a major component fault and is

capable of tolerating multiple, non

concurrent faults.

Easy to Use Software –

WindowsTM

TriBuildTM configuration and

application programming and

TriCommandTM Server

(WONDERWARE© MMI interface

software) are WindowsTM compliant,

making the system easier to use for

the engineer and the operator. For

customers with existing ABB equipment

“backward compatibility” is provided

making upgrading or adding new

facilities economic to implement

TriBuildTM and TriCommandTM Server

can be used with Windows NTTM.

Features include:

• True multitasking capability

• Strategies can be saved on-line

without halting the system operation

• Ability to upload the configuration

• Changes can be made on-line

without halting the system operation

• Bumpless changeover of hot repair

modules

• Comprehensive diagnostic displays

for ease of maintenance

Fault Tolerance and

Selective Redundancy

Improvements in the system to keep a

process plant running safely without

the nuisance of false trips have been

achieved by full diagnostic coverage

of all modules and selective

redundancy.

Processors 3–2–1–0

Input/Output Circuits 3–2–1–0 or

3–2–0

Importance of Transient

Immunity

Comprehensive physical and electrical

isolation combined with asynchronous

processors and software voting

ensures the Triguard SC300E is

immune to transient errors.

Smallest Footprint Size

The Triguard SC300E TMR offers our

customers the best utilisation of

available space. ABB have developed

“plug and play” cabinet layout

configurations that offer pre-designed

hardware for system applications.

Plug and socketed system cables make

marshalling and termination

interconnection quick and easy to

implement.

Processor

Each Triguard SC300E TMR system

contains three processors. Each

processor operates asynchronously in

parallel with the other two processor

modules and receives power from the

redundant power supply units in the

main chassis. A triplicated bus system

on the chassis backplane connects

Key features of the processor modules:

• Intel processor

• Battery backed static RAM for

application logic

• RAM Battery backup supply for six

months

• 1 Mbyte of EPROM

• Real time clock for data logging to

10ms resolution

The Triguard SC300E has an operating

system known as the Real Time Task
