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
