For supervising and
controlling water
and sanitation plants.
Over one in three Swedes comes into
contact with Cactus every day.
Over three million Swedes receive their
water from a treatment plant controlled by
a Cactus system. At Cactus we know your
process and your everyday reality.
Cactus was a pioneer in Sweden when Ringsjö was
the first water works to switch to fully computerised
control and supervision in 1974. Now the plant is on
its fourth generation Cactus system.
An industry institution.
‘Cactus quality’ and our project management ability
have become something of an institution in the water
and sanitation industry. Cactus quality encompasses
everything from punctual project implementation of
the highest quality, to keeping to agreed budgets.
Compared to the large systems suppliers, Cactus is a
small company. However, this means we always have
short decision paths and can customise our solutions.
The biggest factor in the investment.
Investment protection is a philosophy we at Cactus are
happy to admit to. Both our main system and our substations have the longest lifecycle on the market.
And the result? We have been able to upgrade and
re-use all our products in new environments for over
30 years. By considering the long term, Cactus’ systems
are therefore the most cost-effective on the market.
Changing engines mid flight.
Upgrading and commissioning an entire system
without disruptions or shutdowns tends to be the rule
rather than the exception for us and our customers.
We take care of everything from project planning to
the finished plant.
Our tradition of fast, secure upgrades also means
that you, the client, need only commit a minimum
of resources from your organisation.
Absolute operational reliability.
Our long experience of building reliable systems
means our installations maintain excellent availability.
Coupled with the fact that the systems are Linux-based,
this provides first-class performance and the robustness
required for an operational computer system.
We are proud to supply systems to plants
that promote a long-term sustainable society.
The cactus, which we named our company after,
lives and thrives in a demanding environment on
few resources. It also lives in a habitat that sets
tough demands on adaptation and sustainability.

THE CACTUS SYSTEM CONCEPT.
CONTROLLING AND SUPERVISING WATER
AND SANITATION PLANTS.
Cactus’ system concept is part of our main
operational computer system and sub-stations
for controlling and supervising your process.
Our assignments include everything from servers and
workplaces to sub-stations/PLCs and accompanying
programming, commissioning, cubicles and electrical
installation.
Cactus’ sub-stations are available in different versions
for applications ranging from the smallest overflow
monitoring system to Sweden’s largest water and
sanitation plants. The sub-stations have been specially
developed for water and sanitation plants and
operational co-ordination over large geographical areas.
Cactus INGO and CL70 are the fourth generation
sub-stations from Cactus.
Together Cactus’ main system and sub-stations form a
very strong concept for water and sanitation customers
who place high demands on system adaptation,
operational reliability and long-term thinking.
Connecting islands.
Cactus’ operational computer systems can
communicate with all the most common PLCs/substations on the market. As a result, whichever make
you choose you will have a uniform system at the
top operator level. The system also boasts excellent
functions for co-ordinating on-call groups and alarm
distribution – even across municipal boundaries.
Service and support at all levels.
We are extremely keen to ensure you, the customer,
are happy with your system. Particularly as we take
long-term responsibility.
Our long-lasting relations are testament to our customers’
appreciation of our service and co-operation.
Some of our customers even talk about a sense of
family. Perhaps not so strange bearing in mind that
several customer relationships last 20 or 30 years.
EASY TO LEARN.
DEALS WITH THE MOST DEMANDING TASKS.
An operational computer system from
Cactus is easy to learn and has the depth to
cope with the most demanding tasks. The
system is extremely robust and fast. It is also
flexible and suitable for plants of all sizes.
Information system – facilitates operation.
Read more about some of the many parts and
programme packages included in the system.
Secure, yet still accessible.
All functions are accessible throughout the system at all
workplaces. This also applies to on-call workplaces over
all types of communication link. Even so, security is still
high. Authorisation for any function or part in the system
can be restricted to named persons or personnel categories.
Operator functions – all in one place.
The information system is a tool that swiftly gives you
all the information on an object. Click on the object
to obtain ongoing remarks, supplier information, and
operating and care instructions. The current operating
time and service interval are automatically updated
from the system.
Presenting measurement values –
diagrams, graphs or reports.
Pumps, valves and other equipment can be manoeuvred
by clicking on the object. Different panels then
appear for manoeuvring, configuring or obtaining
information about that object. The panels provide
access to all maintenance and system functions such as
alarm statistics, database, property menus and history.
The user interface is strictly object-oriented – making
operation easier for you, the operator.
10
All measurement values gathered by the system are
stored for presentation in the form of diagrams, graphs
or reports. The system has excellent capacity for storing
measurement values over a long period of time. The
values are presented in defined groups chosen by the
operator him/herself and show historic, dynamic or
regression charts.
Passivated, random inspection data labelled as old are
presented in alternative colours and symbols in graphics.
Alarms and events – always at the centre of
the action.
All measurement values are stored in a database that
can be linked to other systems such as operating and
maintenance systems or lab data systems.
Values can also be exported to Excel directly from a
selected graph.
Reports – all the operating data you need.
The system has the capacity to store everything that
happens in your plant – for several years. Alarms and
events are presented in different lists for fast, increased
clarity. Each list has extensive search possibilities for
object, time points, variable names, class of alarm and
sub-stations, for example.
Reports show compilations of operating data in table
format. The data can be presented in daily, weekly,
monthly and annual reports. As with the storage of
measurement values, the reports are accessible in the
system for a long time.
All supervised objects are monitored by measuring
the operating time. Operating time and maintenance
reports are presented based on these data. The same
information is also available in the information system.
All report configuration takes place in user-friendly
configuration tools.
Five alarm classes.
Five alarm classes are normally used: A, B, C, D and E.
The alarm list has direct links to the process image
showing which process the alarm is linked to. The
alarm can be made passive or blocked for a specific
period. Another much-appreciated function in this
context enables you, the operator, to be linked directly
with recommended measures for the alarm and flow
charts for increased clarity.
Your choice of alarm distribution.
You choose the form of alarm distribution in line
with a set schedule whereby each person can choose
which type of receiver (SMS, GSM, MCT) is used, the
sequence in which people are contacted and how many
times each transmission is made.
You can use the same mobile phone on which you
have received the alarm to acknowledge the alarm,
manoeuvre variables and read off measurement values.
11
SYSTEM FUNCTIONS. EXCEPTIONALLY GOOD
OPPORTUNITIES FOR ADAPTING THE SYSTEM.
As a systems manager you also have to be able
to create, maintain and configure parts of the
system simply – without the need to contact
your supplier each time. This results in lower
maintenance costs and facilitates operation.
Hundreds of ready symbols and type objects are
included as standard. Select and use them as they are
or modify them to meet your requirements. You can
also link the images to the real-time database. Various
types of dynamics can be added without having to
write any program code.
A system from Cactus provides exceptionally good
opportunities for changing a host of functions yourself
so they genuinely suit your process and your operators.
The image builder has a built-in test tool which
enables you to test the process image before it goes
into production. You can also modify the status of all
the variables used in the image, thereby ensuring that
all the dynamics work as planned.
Image builder – tailored completely to
your preferences.
The image builder enables you to design images and
forms based on your own ideas and preferences. Image
building is completely object oriented, which means
the same graphic object can be re-used and linked to
different physical objects.
12
Integrated form builder – rapid access to data.
The form builder is integrated in the image builder
and provides rapid access to the most important data in
the process. With this function you can quickly create
easy-to-read forms that enable the operators to modify
various process parameters clearly and conveniently.
Database editor – benefits through
co-ordinated supervision.
Graphic SPRS – creates, documents and tests.
The database can handle any size of processing plant.
For geographic or technical reasons specific to a plant, it
can sometimes be useful to divide the system into several
servers. This type of configuration comprises two or
more operational computer systems in a single network.
Each system can be viewed as a unit within the whole.
All workplaces have access to all information in all
servers. This way of structuring the systems can bring
major benefits through co-ordinated supervision
– within or across municipal borders.
Menu editor – based on operator preferences.
The operator creates and maintains the user interface
through the menu editor. New icons for fast direct
choices can easily be added. New combinations of
graph groups can be completed just as easily. The
system also includes colour scheme options.
The sub-stations are programmed graphically or using
traditional control program coding. Both methods
are transparent, which means you can shift between
program modes at any time.
The programming tool is also very suitable for
documenting code in existing sub-stations. Upload
the code and switch to graphic mode for a fast, clear
presentation of your code.
Maintenance and programming are also straightforward.
As the sub-stations are integrated, you never need to
create cross reference files for communication. Add a
signal and the system is automatically updated both
centrally and locally. There is no need to create a separate
program code for high and low priority alarms and
hysteresis, for example.
Everything is integrated in the system.
13
CACTUS SUB-STATIONS.
PROTECTING YOUR INVESTMENTS FOR
10, 20, 30 YEARS.
Cactus sub-stations are specially developed
for the water and sanitation market.
They are integrated in Cactus’ system
solutions and offer outstandingly simple
maintenance and remote support.
All forms of communication link.
Cactus sub-stations can be programmed over all forms
of communication link, telephone, 3G, radio and
network. Sub-stations spread across large geographical
areas can therefore be maintained centrally from the
main system.
It is important for us to offer continuity in our
development of sub-stations. This protects your
investments for 10, 20 or 30 years into the future.
When older sub-stations betray the signs of ageing,
the existing control program coding can be re-used
intact in new Cactus sub-stations. Re-using tried and
tested control programs means minimal operational
disruption and low modernisation costs for you.
If you wish, we can also access your sub-stations to
make additions, help with commissioning or troubleshooting, for example.

Cactus INGO – for small to medium-sized plants.
Cactus INGO is ideal for small and mediumsized facilities, such as small water and
sanitation plants, pump stations and booster
stations. Cactus INGO is a very compact,
cost-effective sub-station.
Nevertheless, it is still a fully fledged Cactus
sub-station. Compact enclosure, low power
consumption and space-efficient installation
on a DIN rail are other valuable properties.
Approximately 200 I/O can be connected to
INGO.
Cactus CL70 – for large plants.
For supervising large process facilities we can offer the
CL70. Approximately 2,000 I/O can be connected to this
sub-station. I/O can be fitted either locally or distributed
out in the plant.
I/O is connected via Profibus DP and we support a host
of I/O modules. The most frequently occurring are Beckhoff
I/O modules.
Four separate Profibus loops can be connected to the
CL70, each with a maximum of 128 nodes.
The CL70 can also be equipped with a display for local
manoeuvring options.
For the smallest.
Our compact alarm transmitters are used for
small facilities where only supervision or basic
remote manoeuvring is required.
Alarm signals for overflows, burglary or tripped
motor protection, for example, are connected for
transfer to the operational computer system.
The unit is energy efficient and can be
used to supervise analogue signals such as
temperature, level and flow.

Over three million Swedes receive their water from a treatment plant controlled
by a Cactus system. At Cactus we know your process and your everyday reality.
Water and sanitation was where our business first began. Today we can be
found in water and sanitation plants from Trelleborg in southern Sweden to Piteå
in the north. In municipalities large and small.
We have been entrusted with installing up to the fourth generation of
Cactus system for some municipalities, and we regard this as testament that
our systems are among the most economical to install. Absolute operational
reliability is another hallmark of Cactus installations. All of this is included in
what we call investment protection.
A common factor in the sectors in which we operate is that they favour a
society that is sustainable in the long term. The cactus plant, which we named
our company after, lives and thrives in a demanding environment on few resources.
It also lives in a habitat that sets tough demands on adaptation and sustainability.
Feel free to ask our customers what they think about us. “Deliver on time”,
“Very knowledgeable”, “Easy to work with” and “Cost conscious” are some of
the comments repeated again and again in our evaluations. We have worked
with many of our customers ever since we were founded.
Feel free to contact us at Cactus.
We venture to claim that it’s time well invested.
