ABB Plantguard Fault Tolerant Technology Architecture and Software
Plantguard
Fault Tolerant Technology
With an increasing awareness of personnel safety, environmental protection, and process profitability,
the Plantguard fault tolerant control system offers a safe solution with near zero downtime.
It’s powerful, flexible and extremely configurable.
• No compromise design - TUV
certified fault tolerant without
repair time restrictions. Always
fault tolerant, always safe.
• Maximise plant up time - TMR
architecture identifies and outvotes
CPU mismatches and keeps
running.
• Certified safe - certified by TUV to
AK6 and meets IEC61508 SIL1-3
requirements.
Plantguard Architecture
PLANTGUARD EXPANDER
PLANTGUARD CONTROLLER
• Certified to NFPA72C for Fire and
Gas detection applications.
• Simple user programming - familiar
IE61131-3 based programming
allows users to configure both
safety and continuous process
programs.
• Plantguard features full online
(Bumpless) module replacement
with no process interruption.
• HIFT keeps it simple, keeps it safe
Hardware implemented fault
tolerance design reduces operating
system size, minimises systems
software and increases processing
speed, offering the end user the
safest and simplest design.
• Buy only what you need - wide
range of configurable, fault tolerant,
multi function I/O modules to suit
most applications
Fault Containment
Distributed hardware voting prevents hardware fault propagation.
Fault containment allows the system to operate safely with multiple faults.
Up to 320 TMR I/O
in a single chassis
system
Up to 480 TMR I/O
in each expander
Largest I/O Capacity
Plantguard can support systems of over 7000 I/O points. Using the same
architecture for applications from 16 to 7000 I/O means less training and
fewer spares.
