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.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.
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.
Plantguard Software
TMR tolerates faults
The Plantguard TMR architecture will
outvote errors to continue running
safely. This fault tolerant feature ensures
maximum run time of the plant - a major
life time cost improvement factor.
To repair an unhealthy CPU or I/O
module, you simply swap the module
online without upsetting the process
or taking the system offline.
Plantguard controller
This 19” x 6µ chassis contains CPU,
CPU spare slot and 8 slots for any mix
of interface module.

Using Ethernet, Plantguard can
integrate with other process
management products. OPC allows
seamless integration with a host
system. The Plantguard OPC
implementation includes the data
acquisition and alarms and events
protocols. This ensures that all locally
time stamped (1MSEC) data is
transferred to the host system.
Remote Diagnostics
Using the Internet, a Plantguard
system can be configured and
monitored from anywhere in the
world provided local password
protected permission is given.
Remote Expander
Expander chassis (10 per system) can
be distributed over 10km or 6 miles
apart using the fibre-optic expander
bus which saves cable costs and
improves immunity from external
interference.
Signature Analysis Diagnostics
Predictive maintenance diagnostics
provide signature analysis of end device
as well as environmental conditions of
the hardware, alerting the operator to
problems before they happen!
Scan time optimisation
I/O module scanning is user
configurable to suit the dynamics of
the process measurement.
Scan time optimisation ensures the
maximum performance from your
Plantguard system.
1ms time event stamps
True 1ms sequences of events (SOE)
resolution (regardless of system size),
for each alarm threshold, analogue or
digital, input or output point,
configured at the module to give the
operator the most accurate resolution
for process and system level alarms.
Sitewide synchronised time
All Plantguard systems can be
synchronised to any IRIG-B time
source for sitewide synchronisation
of all events to a few milliseconds.
IEC61131-3 Configuration Tools
The IEC1131 Toolset allows you to define
up to 250 individual programs using any
of the 5 specified languages, LD, FBD, ST,
SFC, and IL in each project. Offline
simulation, online de-bug, graphical
interface provides simple and appropriate
tools for configuration, verification and
maintenance of the application logic.
Firewall Protection
The toolset makes use of the Firewall
protection designed into the operating
system to guarantee that safety related
application tasks are isolated from non
critical tasks.
Saves space and cost
Plantguard has the smallest footprint of any
fault tolerant system
Self protected outputs
By replacing troublesome, short-lived fuses
in output circuits with current limited, self
protected outputs Plantguard I/O reduces
maintenance costs.
The widest range of fault tolerant
I/O modules
Ranging from low density modules of 16
points to high density modules with 40 and
60 points, Plantguard I/O makes it possible
to tailor the most cost effective solutions for
each segregated process under control.
Distributed fault tolerant intelligence
Because Plantguard has distributed fault
tolerant intelligence at the I/O module, you
can configure multiple alarm thresholds per
point and active line monitoring
continuously checks sensor and wiring.
