Automation technology for buildings
Hand in hand
for smart solutions
“Home automation,” “smart home,” and similar terms are commonly
heard buzzwords in the modern world, which is one of the reasons
why smart system solutions are the focus of this year’s Light + Building
show, under the slogan “digital – individual – connected.”
installation in terms of comfort, aesthetic
appeal, and expandability are met without
going over budget. The expert tip on pages
13–16 describes how to get started connecting LOGO! to KNX. The articles on pages
4–7 provide more detail on applications of
the KNX module in public and commercial
buildings.
The application range of the S7-1200 Basic
controller is also being expanded with a
number of new features. The new Energy
Meter module, for example, provides energy
management in the lower power range.
And a new failsafe CPU will also expand the
range of applications. A few of these appli­
cations are presented on pages 19–25.
Siemens offers
flexible auto­mation solutions
for residential

buildings
Publicis Pixelpark
Siemens is providing the necessary solu­
tions and technologies to make buildings
more efficient and enhance user comfort –
because today’s developers are of course
looking for energy-saving installation solutions offering maximum comfort and the
widest range of safety and security functions. In the private residential building
sector, however, the new-build phase especially entails a great deal of additional investment, and so there is rarely any spare cash
for complete building automation. In combination with the new CMK 2000 communi­
cation module, selected KNX devices, and
a well-planned infrastructure, LOGO! 8 can
be deployed to handle building automation
tasks. In this way, the demands of a modern

become one
A global leader in the manufacture of compressed air systems based in Coburg in
the Upper Franconia region of Germany deploys LOGO! in conjunction with the
KNX fieldbus in many areas of the building control and utility supply systems for its
factories. Thanks to the easy migration of an energy-saving lighting control to the
high-performance latest-generation LOGO!, in one of the production facilities the
number of base units has now been halved from two to just one using a KNX module.
Founded in 1919, Kaeser Kompressoren SE today employs more than
5,000 people worldwide – with just
under 2,000 of them in Germany.
The company’s product portfolio
covers the full spectrum of compressed air generation, conditioning,
and distribution. The growing familyowned business successfully markets
its highly reliable, economical, and
energy-efficient products and related
services through branch offices and
exclusive partners in more than 100
4
countries. Production facilities are in
Germany, at sites in Coburg and Gera.
Two new production buildings and
an additional administration building
are currently under construction at
the company’s headquarters location
in Coburg.
The company has a long-standing
sys­­tem partnership with Siemens.
“We particularly like the standardization, compatibility, and almost unlimited combinability of the solutions.
We use a wide variety of Siemens products in our utility supply and building
control systems, from transformers to
KNX modules,” explains Stefan Gruber,
head of Kaeser’s electrical infrastructure and systems technology department. He cites further benefits: “We
can obtain all the electrical components we need from a single source;
we can rely on expert advice and sup­
port in all areas; and long-term worldwide availability of replacement parts
for the products is assured.”
GO! 1/2016
Lighting as and when needed
Gruber operates about 100 LOGO!
units in his department alone, mostly
in combination with KNX, as a flexible
and convenient bridge, as it were,
be­t ween the KNX world and the conventional world. “It is something that
has developed over many years,”
reports KNX Manager, Christian Pohley,
who programmed his first LOGO! way
back in 1999, in the second year of his
apprenticeship at Kaeser. “Back then
it was used to switch the lights on and
off in different factory areas, as well
as providing a central switch-off function, controlled by buttons on a panel.
Today, our lighting control with LOGO!
is more diversified, and we use it in
multiple buildings.”
In the distribution center, for example,
until recently two Logo! 0BA7 units
connected to a KNX module switched
the fluorescent ceiling lighting –
grouped by area – in three separate
phases: “Brightness sensors detect
how much light is falling from the
outside onto specific points in the
logistics center precalculated by us,”
says Gruber. “The light strips beneath
the ceiling are divided into thirds, and
if more light comes in from outside
LOGO! switches off one-third of the

overhead lights in the area concerned,
then a second third in the next phase.
With this solution we save around 25%
on our electricity bill for lighting. With
KNX alone, that could only have been
done at much greater expense and
effort.” The final third of the light strips
provide the basic lighting that always
stays on.
Migration in two hours
The migration to the new LOGO! 8
with the new LOGO! CMK 2000 KNX
module took Pohley just two hours.
“Of course, my many years of experience helped,” he says. “Drag-and-drop
programming is very easy and has not
changed essentially since the early
days. But the best thing is that I now
need only one unit instead of two.
The reduction was possible because
with the new KNX module I am able
to configure the 50 communication
objects via KNX, freely and indepen-
dent of the analog and digital inputs
and outputs – even with a maximum
number of LOGO! hardware modules.”
Another benefit: “The LOGO! and KNX
module no longer have to be installed
in the same place, because the new
module has network capability and
is a stand-alone unit. And that adds
flexibility too: I can deploy the module
where it’s most useful at any given
time.”
Based on this positive experience,
Pohley will also be controlling the
light­ing in the two new production
buildings in Coburg with the LOGO! 8.
And he is also looking to install the
likewise energy-saving ventilation
and shading control that is already
in use at the Gera plant. “There the
LOGO! operates as a timer – again at
an un­b eatably low cost,” he says. “It
receives the DCF [German longwave
time signal] from the weather station
on the roof via KNX, and I have programmed it so that, depending on
the season, it opens and closes the
blinds and the windows at specific
times of day.”

numerous models, such as one for a turnstile gate (see

Applications include signaling for nonsafety and systemrelated faults, such as in heating and ventilation. They are
logged by LOGO! for maintenance purposes and sent via
KNX to the home server, which then in turn sends e-mail
or SMS text messages to the appropriate personnel.
Kaeser also uses LOGO! for intelligent c­ ontrol of the two

On the
safe side
The vacuum unit in the power substation of
a retail and business park must meet stringent
requirements, including trouble-free operation,
easy operator control, and a secure KNX
connection between the distributed controls
and the central master control system. LOGO! 8
and the new CMK 2000 KNX module meet
every requirement.
The Stücki Shopping Center in Basel, Switzerland, which
also incorporates a hotel and business park, is located on
the site of a former dye works. At the heart of the complex
is the power center, featuring an absorption refrigeration
unit that generates both heat and cold utilizing the heat
discharged from a special waste incinerator and a sewage
treatment plant. This recovery of waste heat allows the
buildings to be heated without using fossil fuel.
The liquid separator separates the
air/water mixture and removes the air
from the plant water

Publicis Pixelpark/J. Koch
As the water is routed from the heat exchanger to the
refrigeration unit, the design results in air collecting in the
pipes. A vacuum system from Busch AG has been installed
to continuously suction off the air. If the refrigeration unit
were to draw in air, it would malfunction. The machine
would be blocked and would come to a stop. The two
pumps in the vacuum unit are connected to a Busch liquid
separator, which separates the air/water mixture and
removes the air from the plant’s water. As the water collects in the bottom section of the separator, the air rises
into the top section. Once the bottom chamber is full, the
float switch sends a signal to the LOGO! 8–based vacuum
unit controller. The logic module opens the valve, and the
tank is emptied.
LOGO! 8 as an intelligent controller in the KNX system
Electronics company Schroer Elektronik, located in Steinen
in the southern German state of Baden-Württemberg, has
been manufacturing control cabinets and systems since
1991. Its services include the creation of automation solutions for pump systems, and it was the pump manufacturer
GO! 1/2016
The second component of the project for Schroer was to
connect the vacuum unit control to the central control
system of IWB, the regional utility company in the Swiss
canton of Basel-Stadt and energy supplier for heating and
cooling operations of the Stücki power center. The new
LOGO! CMK 2000 communication module provided the
automation expert with the ideal solution for deploying
the logic module with the KNX module as an intelligent
controller within the KNX system as the foundation
for the retail and business park’s building management
systems. LOGO! 8 connects the KNX module via Ethernet.
This means all the input/output addresses are left free
for digital and analog signals. The operating states of the
vacuum unit are transmitted directly over the KNX bus to
the central control system and enable the plant operator’s
building services to monitor operations from the technical
services center.
Professional backup from Siemens support
Schroer has been using products from the LOGO! system
line to execute a wide variety of automation tasks for
years. “Reliability is one of the key benefits,” he says. “We
have never had a faulty LOGO! back from a customer.” And
when the new KNX module was launched, the automation
and PLC expert quickly recognized its benefits too. “Thanks
to the KNX interface, IWB’s service department is able to
access the LOGO! directly from the control center and
retrieve information on the operating states of the vacuum
unit. The customer controls the systems in the power
center but at the same time can monitor states centrally
and intervene as necessary,” Schroer explains. The plant
states are indicated on the LOGO! display as well as on a
remote HMI. And the same information can be viewed on
a monitor in the control center.

that contracted company owner Bernd Schroer to design
and implement the controls for the vacuum system in
the power center of the Stücki Shopping Center. The PLC
specialist chose to automate the plant with a LOGO! 8
12/24 RCE logic module.
Experts who appreciate the LOGO! solution:

and IWB systems engineer Roger Hafner
Configuration made simple
Schroer and his staff configured the control set-up for
the vacuum system using the LOGO! Soft Comfort V8 software, which enables programs to be written and implemented quickly and easily. Communication functions are
programmed by drag and drop. Individual program segments can be simulated, optimized, and merged into the
overall functionality. “The functionality is rounded off
by tools for compiling the documentation, with a switch­
­ing program, comments, and parameter settings,” says
Schroer. The operator control software offers different
user interface languages and can be programmed accord­
­ing to specific requirements. Processes and errors are
­visualized on the HMI. When LOGO! reports an error to
the system, the service engineer can click on a button
to view the details of the operating state.
Publicis Pixelpark/J. Koch
Schroer is full of praise for the professional backup provided by the Siemens support staff: “Service backup is
always accessible, and they always respond without
delay. Our questions regarding the KNX interface were
answered expertly.” The success of the shopping mall
project has given Schroer plenty of optimism for the
future. “We have high demands in terms of the functionality and u
­ ser-­friendliness of our solutions. In Siemens
we have a reli­able, expert partner for all aspects of automation.”

Five-star automation
for guests and staff
In the Princess Andriana Hotel & Spa in the
former fishing village of Kiotari on Rhodes,
electrical, instrumentation, and control
design specialist Pantelis Katsidonis & SIA EE
developed and implemented a cost-effective
solution for the monitoring and control of
building functions. The state-of-the-art room
electronics concealed from the guests’ view
feature LOGO! microcontrollers.

At the five-star Princess Andriana resort, state-of-the-art
management systems implement the buildings’ comfort
and safety functions, all controlled in an energy-efficient
manner by LOGO! in conjunction with a Siemens building
automation system. The resort offers a total of 481 guest
rooms spread over a main building and several bungalow
complexes. There are single, double, and family rooms,
with balcony, terrace, or access to a private pool. The main
building houses a lobby, a reception desk, an Internet
lounge, restaurants, and coffee bars, as well as a spa area
and fitness room. Illuminated, music-activated water fountains provide breathtaking visual effects in the evening
hours.
The ­contracting team from Pantelis Katsidonis & SIA EE
has ­specialized in electrical installations and energy management system design since 1992. Timed for the start
of the 2015 season, the electrical, instrumentation, and
control design experts upgraded the Princess Andriana’s
power switchboard, which now incorporates KNX building
­automation modules. Six LOGO! 8 units with expansion
modules and analog outputs were installed in the remodeled switch­board.

tion. The rooms’ air-conditioning and lighting are controlled
according to whether there are guests present. A master
button centrally switches all assigned functions on and off.
Remote support via VPN
To ensure smooth operation of the systems, the hotel’s
building services manager presets the set-point values,
which are then automatically executed by the program
written using LOGO! Soft Comfort. One logic module serves
as the master, transmitting the control commands to all the
subordinate modules. One benefit of the new version of
LOGO! is remote technical support via a closed communi­
cations network known as a virtual private network (VPN).
From the LOGO! master unit, the engineer controls devices
including the inverters through a web browser and is able
to intervene in processes via the browser in the event of
any errors.
LOGO! also activates a welcome message and the room
lighting when guests insert their room card in the slot on
the door. When the guests enter their room, the TV turns
on, showing a message such as “Welcome Mr./Ms. Smith,”
followed by a promotional film about the hotel. Guests
are able to operate all the in-room electrical systems with
switches from the Siemens Delta switch range, as well as
controlling the lighting, the blinds, and the air-conditioning
system. When the card is removed when the guests leave
the room, all electrical devices are automatically turned off.
This saves energy
The Greek electrical, instrumentation, and control design
specialist has also implemented another hotel project
based on LOGO! 8. In an expansion project at the five-star
Atlantica Imperial Resort & Spa on Rhodes, the logic module
was deployed for functional control covering 28 luxury
apartments. The intelligent control system implemented by
LOGO! 8 significantly reduces the hotel’s energy consump-

Optimally coordinated systems
To ensure that all technical processes run smoothly, safely,
and energy efficiently, the building automation and the
heating, ventilation, and air-conditioning (HVAC) solutions
were implemented using the KNX communications standard.
The Gamma building control has proved to be extremely efficient, offering high levels of comfort for guests, including
optimal coordination of the lighting, sun protection, and
in-room air-conditioning functions. These functions adapt
to changing requirements in the course of the day, providing
a highly energy-efficient solution. Each lighting and HVAC
function can be centrally monitored and controlled, including
monitoring for any malfunctions.
The building automation solution comprising LOGO! and
a KNX bus system was chosen because of its flexibility and
expandability. The electrical, instrumentation, and control
design team also established the technical preconditions
to control every room’s functions – whether lighting, air-­
conditioning, or blinds – from reception. The programming
of the room controls worked very well, and the team met
the deadline for implementing the project by the start of the
season. There will be more automation projects featuring
LOGO! – everyone involved is sure of that. siemens.com/logo

Elektro Richter KG, Naila-Lippertsgrün, Germany
In the church of the small Lutheran parish of Töpen in
the Upper Franconia region of Germany, state-of-the-art
control technology keeps everyone warm during services.
Last December, the church’s heating and lighting systems
were upgraded with two LOGO! 8 units with a Comfort
Panel and remote communication capability.

More
comfort in
church
St. Martin’s church in the 1,000-person
parish of Töpen has a welcomingly bright,
friendly interior enhanced by decorative
floral paintwork on the gallery walls, ceiling,
and pews. Concealed among the images
are infrared heat emitters, which ensure
comfortable temperatures during church
services, funerals, and other events, even
on the coldest winter days.
Richter, son of the company owner and head
of the technical department, says: “The firsttime use of a Siemens Comfort Panel made
the solution in Töpen very u
­ ser-friendly. We
chose Siemens and LOGO! 8 mainly because
the two LOGO! basic modules are so easy
to connect in the maximum configuration
and are also easy to connect to the panel
via a switch module.“
As part of restoration work on the church
building, electrical contractor Elektro Richter
KG from nearby Naila-Lippertsgrün was
engaged to update and simplify the instal­
­led systems. Established 75 years ago and
now operating throughout Europe, Richter
employs 50 people and runs a lighting shop
in Köditz. The company had in fact already
performed similar work in other churches, in
some cases using LOGO! Electrician Daniel
More compact, easier to use
Previously, the lights and heating were
­controlled by a console with many buttons
soldered together by a member of the
church community in his spare time. “By
dismantling it and replacing it with the
Comfort Panel, we made space in the equipment room,“ says Richter. “We were able
to reduce the energy consumption of the
heating system, but above all we made the

GO! 1/2016
system easier to control. The CMR 2020
module supplied as a free extra synchronizes the time, meaning services always
begin punctually, and also enables ope­
rators to switch the heating on or off as
required by sending a text message from
a cell phone.” The modification, programming, and testing were completed in about
two weeks, just in time for Christmas. A
LOGO! 8 logic module with two DM16 24R
digital expansion modules controls the
lighting. Lamps, spotlights, and chandeliers
can be turned on and off zonally as before.
New features in this application are the
status indicator on the Comfort Panel and
the centralized on/off function.
Energy-saving fine adjustment
The heating posed much greater challenges.
For the regular Sunday services, Richter pro-
grammed a three-hour preheating mode,
which now no longer needs to be started
manually but runs automatically at an individually specifiable time. Depending on the
temperature measured by the temperature
sensor inside the church, the heating starts
up three hours or – after appropriate pauses
– two hours or one hour before the service.
Since 1789, St. Martin’s
Based on predetermined heat-up times, the
LOGO! calculates the required preheating
time to reach the target temperature. If a
freely programmable maximum temperature
is reached or exceeded inside the church,
the heating remains completely off. “This
graduated operation saves energy, because
previously the heating was running continuously every three hours, even when we set
the system for shorter heating cycle times,”
says Richter. He further improved the cycle

special feature in the Töpen church remains,
in that the cycle itself can also be indivi­d ­

always lasts 30 seconds, but it can be split
into two manually as required, such as
15 seconds heating and 15 seconds pause,
10 seconds heating and 20 seconds pause,
and so on. A further comfort bonus: the
cycle can be set separately for each heating
circuit, comprising three pew heaters, by
means of touch sliders on the Comfort
Panel.
A second timer in the LOGO! handles services or other events outside the normal
service schedule based on the same heating
principle, with heating start times freely
selectable by day and minute.
There are also two external timers: one programmed by Richter each December with
a calendar function to provide automatic
heating for “one-off” services during the
year (such as at Easter or on Whit Sunday),
and one with which the pastor can switch
the heating on and off manually at any
time, such as to protect against freezing.

Color-coded graphical views of the church’s

­indicate to the operator which pews and/or
galleries are currently being heated.
Along with the easy connectivity by drag
and drop, Richter likes the flexible modular
expandability of LOGO!: “Including the
Comfort Panel, I get practically all the elements of the solution from a single source,
from one point of contact, and they all
work perfectly together. And when I did
have a question – specifically about the
Comfort Panel, which I was using for the
first time – I got help immediately.”
The high maintenance required by the
­previous control console was cut virtually
to zero by the state-of-the-art technology:
“LOGO! is a standard product that I can
reorder at any time. If I needed to replace
something, all I would need to do is reload
the existing program,” Richter concludes,
looking ahead. “Also, if the requirements
for any of our future church upgrade
­projects are similar, I can reuse this pro­
gram, and I will just have to adjust minor
details.”

Expert tips: Connecting LOGO! 8 to KNX
LOGO! 8 to KNX:
Just try it
Together with the new CMK 2000 module for connection to KNX
and selected KNX devices, LOGO! 8 offers a highly flexible automation
solution that provides customers with a wide range of benefits and ease
of operation at an affordable cost and can be updated to accommodate
changing room usage at any time in the future.
The following briefly describes how LOGO! 8 can exchange data
with other KNX devices. There are many vendors of KNX devices,
so only the basic configuration of LOGO! 8 on the KNX is outlined
here.
13
GO! 1/2016
What do you need to get started?
– LOGO! Soft Comfort demo version +
– ETS5 demo version
• 50 freely configurable communi­
cation objects
Both are available to download free from
the Internet (see link listing at end).
• Maximum usable LOGO! capacity
Screenshots property of Siemens AG
To check out the programming requirements, all you need initially are two things:
The LOGO! 8 base unit and the
CMK 2000 KNX module communicate
via Ethernet. This delivers significant
advantages over previous versions:
Figure 1
• Ability to use logic operations and
time and analog functions within the
LOGO! program as well
We assume you are already familiar
with LOGO! programming, and so we
will focus on connecting to KNX:
1. Transmitting a binary signal from
LOGO! 8 to a KNX device
2. Transmitting a binary signal from a
KNX device to LOGO! 8 and integrating
into the LOGO! program
For example, a fan is controlled by an
on/off delay (Figure 1).
In LOGO! Soft Comfort there is
­initially no indication as to whether
a KNX module is connected or not.
Figure 2
Depending on the application, a telegram can be sent to KNX either directly
from the input (without even needing
to use the input in the LOGO! program)
or from the output (if there are multiple links, also by way of a flag in the
program).
The best view for beginners after
opening the ETS software to create
a new project is “Devices.” Insert
the LOGO! device into the initially
empty project with the CMK 2000
(Figure 2).
Figure 3
To be able to use the CMK 2000 in
ETS, first import the matching
product ­database. You will find this
knxprod file ready to download at
siemens.de/gamma-td?te2=CMK2000
Figure 4

Take care: there are various previous
­versions. It is the file displayed here
that must be imported.
GO! 1/2016
After the database has been imported, the
CMK 2000 module is displayed in the product
catalog and is available for further use in the
project.
Now add the CMK 2000 module to the
project by choosing “Add device.” It is then
displayed in the device list (Figure 3).
Figure 5
When you select the module from the list
and then open the “Parameter” tab at the
bottom of the screen, you first see the
basic settings for the CMK 2000 module
(Figure 4).
It is important to enter the IP addresses of
the LOGO! base unit and the CMK 2000.
In the example, the default addresses have
been retained. The other settings are irrelevant for the time being.
Figure 6
Now specify a communication object for
data exchange, such as for channel 1. When
you select channel 1 and specify the direction of transfer from LOGO! to KNX, you
see a list of data types to choose from. In
our example, digital input I1 is to be used
(Figure 5).
As in the LOGO! program, input I1 is selected.
The default data type matches the signal
(Figure 6).
Figure 8
Figure 7
Next, assign the communication object now
shown for channel 1 to a group address.
To do this, click on the row of the communication object in the “Group address” box,
choose “Link with,” and assign a new group
address with an appropriate name (Figures 7
and 8).
Later, the signal in the group address will
be linked to the communication object of an
actuator on KNX.
Figure 9
To process a switching signal from a KNX
device in the LOGO! base unit, select the
opposite direction for the communication
(Figure 9).
Here, flag 10 in the LOGO! device is controlled over channel 2. The program in the
LOGO! device is then as shown in Figure 10.

Analog signals are handled similarly. This
topic is not discussed in detail in this article,
which just presents the most basic scenario
where the analog input does not need to be
used in the LOGO! program. Only the transfer
of the value at the terminal of the analog
input to KNX is enabled (Figure 11).
The transfer from KNX to LOGO! 8 is shown
in Figure 12.

Here, the value must be included via an
analog flag for further processing in the

In the example, the heating is switched on
at low temperatures, and off above 200

analog values from 0 to 1,000).

Asbestos is a natural mineral fiber that does not burn, decay,
or rust and that acts as an insulator against cold and noise.
Thanks to its durability, asbestos was widely used in the
past to make corrugated roofing boards and as insulating
material. It has in modern times been declared a harmful
­pollutant, and its use is banned by law. Even the minutest
quantities of fibers entering a person’s airways can cause
incurable bronchial and lung disease. However, asbestos
­residues are often still found in industrial plants and residential buildings, so major efforts must be made to clear the
properties affected. These clearing operations can be quite
complex, depending on the type of asbestos-contaminated
material installed, because no fibers can be allowed to be
released; they must be captured in their entirety and disposed of in such a way as to eliminate any risk to human
health or the environment.
deconta, based in Isselburg in the Lower Rhine region of
Germany, specializes in helping companies clear asbestos
residues. One of the technologies the company develops and
manufactures is mobile air locks through which personnel
enter and exit contaminated zones. The air locks comprise
multiple chambers, depending on the standard to which the
clearance work is being carried out, divided into so-called
black and white zones. Exiting from the contaminated environment, a worker enters the first air lock chamber in the
black zone. After a precleaning stage, the worker showers
in a special room.

deconta develops and manufactures high-­
end decontamination systems based on both
existing and new technologies to prevent
asbestos residues such as those found in
industrial plants and residential buildings from
being transported into the environment,
either by way of uncontrolled air exchange
or by adhering to work clothing. The systems
are automated with LOGO! 8.

Interface to remote monitor
As part of a comprehensive upgrade to deconta’s tried and
proven “deco mobil” mobile air lock, the existing manualswitch-based control system was replaced by the LOGO! 8
12/24 RCE logic module, installed in the air lock system’s
control cabinet together with the DM8 12/24R and AM2
digital and analog expansion modules. This solution enables
even complex standards to be met, and sensors can be
installed to make operations even safer. To visualize the air
lock functions, LOGO! is connected to the KTP 400 Basic
color touchscreen display via the Profinet interface. The
interface is also used to program the micro-PLC with LOGO!
Soft Comfort. Another benefit of using the KTP 400 is the
ability to customize the input screens via an intuitive menu
structure, as well as multilingual user guidance on the HMI.
This means deconta’s customers are able to easily configure
the deco mobil to meet specific on-site requirements and
can monitor the system to ensure safe, trouble-free operation. Operating states are continuously displayed, enabling
timely intervention – such as filter replacement, for example
– to maintain safe operation.
deconta engineer Martin Hemming (right)
explains his app to Siemens sales executive
Björn Muthmann
To make controlling the mobile air locks as user-friendly as
possible, deconta engineer Martin Hemming has developed
a smartphone app. He explains: “LOGO! sends an SMS text
message to a smartphone, which translates the commands
into understandable graphics. Users can see at a glance
which air lock functions are active. Data displays include
the water and diesel tank fill levels, the water and heating
temperatures, the pump mode, and the lighting status.”
The smartphone app can also be used to control all LOGO!
­functions remotely. At the click of a button in the user’s
smartphone app, a text message is automatically sent to
the ­communication module, which immediately returns a
confirmation.
“Our plan to make tried and proven systems even safer and
more efficient with LOGO! has been an unqualified success,”
reports deconta CEO Christian Krolle. “We can now put
together complex sequences that were not previously feasible. Functions that we previously had to set manually are
now controlled by the logic module. It activates the complete system on a timer basis, for instance, and ensures that
the air locks are preset to the right temperature and ready
for operation at the start of each shift. That provides enormous improvements in energy efficiency.” In some cases,
for example, the law requires that the vacuum unit be kept
running for a certain time after a decontamination cycle,
a job that Krolle believes LOGO! handles very well. Once a
week the LOGO! timer activates the water heating in the
airlock tank to prevent the growth of legionella bacteria.
Krolle concludes: “The automation makes the decontami­
nation work much safer and minimizes the health risks of
workers in the decontamination area.”
deconta
deconta’s engineers enhanced the LOGO! solution to work
with mobile communications using the CMR 2020 commu­
nication module. It is designed to work with the LTE (Long
Term Evolution), UMTS (Universal Mobile Telecommunications System), and GSM (Global System for Mobile Communications) standards. deconta uses the communication module
for remote monitoring, alarm signaling, and control of the
mobile air lock systems. It also allows users to track a mobile
air lock by GPS and view its current location on Google Maps.

This process ensures that workers do not come into con­
tact with the hazardous asbestos fibers, and the worker
can then safely get dressed in the white zone. Negative
­pres­sure prevails throughout the system, and there is also
a guided airflow. Asbestos fibers must be prevented from
escaping from the work area into other rooms or the out­
side environment, either through openings or by adhering
to clothing.

Since the installation of
229 solar modules that auto­
matically track the movement
of the sun, the Bindlacher Berg
solar power plant has been
producing almost a third more
yield. The tracker units are
con­trolled by an integrated
solution based on Simatic
S7-1200 controllers and the
Solar Tracking Toolbox.
Bindlacher Berg solar power plant:
229 dual-axis sun trackers deliver
approximately 2.4 MWp of power
The investors in the Bindlacher Berg
solar power plant near Bayreuth,
Germany, have good reason to be
pleased. The 229 solar modules on
the 7.3-ha former military barracks
site can now – either individually or
col­lectively – be automatically aligned
exactly to the sun on two axes, and
this yields over 30% more power
­com­pared to fixed installations. Each
tracker has a power output of 11 kWp;
the total of approximately 2.4 MWp
can power as many as 1,000 house­holds.
Automation tried and proven
in industry
The solution was implemented by
Gerlitz elektro-gmbh based in Bayreuth.
The project team, headed by engineer
Matthias Pellert, implemented an
­auto­­­mation solution based on modular,
ex­­pandable Simatic S7-1200 Basic
­control­lers and the modular Solar
Tracking Toolbox, in which Siemens
has bundled various largely preas­

from Siemens appreciate the fact that
the system can be controlled and
moni­­­tored both locally and remotely
sembled and tested functions, applications, and concepts for special tracking
tasks as well as viable, modifiable
sample projects.
The control system, tried and proven
in industrial applications, is rated for
operating temperatures from -20°C
to +60°C, which means it can be operated in the on-site switchboxes on the
trackers all year round. The selected
CPU 1212C is also powerful enough
to handle online tracking computation
based on the high-precision Solar
Position Algorithm created by the US
National Renewable Energy Laboratory (NREL), which Siemens has implemented in a licensed base module for
its control system. The algorithm is
able to determine the position of the
sun depending on the time of day to
an accuracy of 0.0003° for the next
6,000 years.
Distributed control system
The CPU computation offers the
advantage that the trackers operate
with no higher-level control and can
work autonomously. The control
systems also have enough resources
for all other tasks, including commu­
nications (also via web server) and
sensor and actuator monitoring. With
robust absolute value encoders, which
are connected in a simple and failsafe
manner to the S7-1200 by a CM 1241
communication module via an RS485
interface and using the Modbus protocol, every controller knows the position of “its” tracker even after a power
20
failure, and on resuming is able to
move it rapidly to the correct position.
To avoid unnecessarily high network
loads, not all 229 trackers are moved
simultaneously. Instead, they are
moved in groups at offset times. This
function, too, is parameterizable from
the free Toolbox.
Integrated to create a modular
solution
The Simatic S7-1200 can be easily
­configured and programmed via
TIA Portal, as can the Simatic HMI
Comfort Panel for monitoring and
con­trol of the solar power plant in
the central control station. For monitoring and control, systems inte­
gra­tor Gerlitz adapted the precompiled sample appli­c ation for the
Simatic WinCC ­visualization system
and generated its own user interface
by which all 458 tracker axes are
­monitored and controlled. Another
basic function of the Solar Tracking
Toolbox, so-called back tracking, has
also been implemented. This prevents
solar modules from overshadowing
each other when the sun is low in the
sky. At high wind speeds the modules
are likewise moved automatically to
a safe storm position. Snow can also
be tipped off the modu­les in winter
by setting them at a greater tilt angle.
Remote access via VPN, tablet,
or smartphone
A Simatic IPC 427C industrial PC
(Microbox PC) acts as the master computer for the entire solar park. The
Microbox runs a standardized communication algorithm; detects the tracker
controllers in turn over multiple channels via an Ethernet connection; and
visualizes their operating state, current
positions, error messages, and other
operational data. A specially developed
data concentrator optimizes commu­
nications. Error messages can be sent
by e-mail and text message (SMS) to
freely definable recipients.
Operators can also log in to the
sys­­tem from home via a VPN (virtual
private network) using the Sm@rt­­
Server WinCC option. Remote access
is even possible with a tablet or
­smart­phone, using Siemens’ specially
­developed Sm@rtClient app. Generally,
authorized users are able to access
the plant re­m­o­t­ely to control and
monitor it without any engineering
system. This is most easily done using
the web server built in to every tracker
controller, which provides precompiled customer-­specific HTML pages
containing relevant data for down­
loading.

The technology
dictates the yield
Thanks to its relatively high peak power output, the
­Bindlacher Berg solar power plant is ranked third among
all tracking photovoltaic plants in Germany. We asked
Michael Krokauer, chief executive and technical manager
and member of the plant’s investor group, about his
experience.
Mr. Krokauer, the Bindlacher Berg solar power plant
has been running the tracking system since mid-2014.
How is the system meeting your expectations under
what are, after all, the often gray skies of the Upper
Franconia region?
The plant has been much more stable and reliable since
the system was commissioned. Above all, however,
we are well on our way to achieving the theoretically
possible yields in practice, both when the sun is shining
and on cloudy days. Our yield is currently at least 30%
higher than that of fixed installations, with still more
potential to improve. We are thoroughly satisfied with
every sunbeam that we are able to optimally convert
into electrical power, which is then fed into the public
grid in accordance with Germany’s Renewable Energy
Act (EEG).
What were the key factors in that success?
The special functions of the Siemens control systems,
including the back tracking function and optimized
tracking control, enable us to achieve more than ever
before, even when confronted with unfavorable situations. The technology dictates the yield.
»Our yield is currently
at least
30
percent
higher than the yield
of fixed installations.«
Our replacement parts supplies are now also assured
for many years, and the breadth of the Siemens product
portfolio offers alternatives if new weaknesses are
revealed in the original equipment. So our investment
is secure for the future.
That’s right. That is also what I meant by reliability.
And the industrial automation technology provides a
guarantee in that respect. With regard to malfunctions
or failures, we and our partner Gerlitz have a range of
options for secure remote access to the plant via the
central master computer. The tracker controllers automatically report errors via SMS and e-mail, and we are
able to see what is wrong and what needs to be done
to remedy the situation, wherever we may be. That
reduces downtime, eliminates unnecessary travel, and
thus cuts costs.

Other essential factors in achieving sufficiently
high margins are keeping maintenance costs within
manageable limits and quickly detecting and elimi­n­­a­ting failures, correct?

The K&K weighfeeder features
two weighing lines and has a
resolution of 0.002 g
K&K Wiege- und Dosiertechnik GmbH, Fernwald, and Rohrbach Elektrotechnik GmbH, Butzbach, Germany
Fully automated weighing
and feeding
Automatic weighfeeders must operate precisely, quickly, absolutely reliably, and
(as far as possible) around the clock – also without operating personnel. This is
what wholesale, retail, and industrial customers expect. A solution comprising
the Simatic S7-1200 controller and the ET 200AL distributed I/O system optimally
meets these requirements.
K&K Wiege- und Dosiertechnik, based in Fernwald in the
German state of Hesse, has been designing and manufacturing automatic weighers, counters, and feeders as well as
complete packing lines for more than 25 years. CEO Egbert
Ruß is focused on top product quality and reliability and
always employs state-of-the-art technology. That was also
the case when he developed and successfully commissioned
a fully automated weighfeeder for an electrical engineering
company in partnership with contractor Rohrbach Elektrotechnik from Butzbach, Germany.
22
Maximum precision for the smallest items
Siemens Solution Partner Holger Rohrbach is a specialist
in applications of the Simatic S7-1200 Basic controller,
which was the microcontroller he used to automate the
weighfeeder. The weighfeeder collates tiny items with single
weights of 0.07 g to create packaging units of an exact
­quantity. The quantity is determined by weight. The weighfeeder has a resolution of 0.002 g, with a tolerance of one
item above the specified quantity. The controller rules out
the possibility of one item being omitted.
GO! 1/2016
»Customers are often surprised at what can be done
with the Simatic S7-1200, especially on smaller plant
units. And if it is not quite adequate, we can easily
transfer a project to the Simatic S7-1500.«
Siemens AG/HL Studios
Holger Rohrbach, K&K Wiegetechnik
If two or more items above the specified quantity fall on
the scale, the batch is rejected and the items are fed back
in. The packaging process also runs fully automatically
overnight, outside shift operations; all the personnel need
to do is fill up the container in the evening.
The weighfeeder operates with two weighing lines of differing widths. The items are fed in by vibrating conveyor
channels. The wider channel delivers 90% to 95% of the
target weight. Single items are then fed in via the narrow
channel until the desired total weight is reached. The
weights are measured by two Siwarex weighing modules.
Wiring minimized
To enhance reliability, K&K and Rohrbach eliminated vir­
tually all wiring, because “80% of all malfunctions in such
systems result from wire breaks,” Ruß asserts. So all the
inputs and outputs – the digital ones for the valves and
limit switches and the analog inputs for the ultrasonic fill
level sensors on the vibrator – are connected by way of
the new compact ET 200AL distributed I/O system with
IP65/67 protection. Ruß adds: “Having the distributed I/O
directly in the plant on Profinet is in our view a major
improvement in terms of the quality of our systems. The
possibility to use much smaller switchboxes thanks to the
relocated peripherals will also pay off in the future.” He
agrees with Rohrbach that they have found a standard
solution with which additional markets can also be opened
up. “We believe a system of this kind will be highly attractive wherever goods are currently still weighed manually,
because a rapid amortization period of two years is
realis­tic.”
TIA Portal. As a result, different target weights can be
achieved with high accuracy even at the bulk feed stage.
Then only a small quantity must be fed in to provide fine
adjustment in the final stage. All this takes place with
extremely high levels of user-friendliness. The operator
just needs to enter the target weight, and the control
­optimizes itself.

connectivity and communicates with the controller

Siemens AG/HL Studios
Self-optimizing control
A major highlight of the solution is the volume flow control
accuracy on the vibrating conveyor channels. Because the
bulk product can be distributed differently when fed in,
the speed and frequency of the vibrator must be adapted
depending on the fill level. The more effectively that is
done, the faster the plant can run.

The balloon
in the bottle
The filling machines from
Leibinger GmbH in southern
Germany might soon see the
climate killer CO2 disappearing
from the beverage industry.
The company’s revolutionary
“Balloon-Style” technology is not
only environmentally friendly
and resource efficient; it is also
the fastest filling method in
the world. The machines are
controlled and monitored by
Simatic S7-1200 Basic controllers.

Making beverage bottling machines without CO2:
CEO Benedikt Leibinger (right) and his automation
specialist, Christoph Mutschler
To preserve the taste, appearance, and
shelf life of beer, wine, sparkling wine,
and soft drinks, the beverages must not
come into contact with oxygen during
the bottling process. This is why the
beverage industry has always flushed
oxygen out of bottles beforehand with
carbon dioxide (CO2) – a complex,
costly, and environmentally unfriendly
method. “Especially for smaller producers, who are our customer base and
who often look to gain a competitive
edge through ecologically sustainable
production, that is uneconomical and
bad for their image,” explains Benedikt
Leibinger, whose Leibinger GmbH
company specializes in bottle-filling
machines. To address these issues, he
got together with his designers to devise
a method that eliminates the need for
CO2 altogether.
Award-winning method
Leibinger’s now patented solution,
­Balloon-Style, removes the oxygen with
the aid of a vacuum. A tube made of
the recyclable plastic TPE, which needs
to be changed only once a day, is fed
into the empty bottle and inflated to
create a balloon. Due to the internal
pressure, it presses completely against
the inside wall of the bottle, pushing
the oxygen out. The beverage deflates
the balloon again as it is poured in, and
the balloon is removed from the bottle.
As well as eliminating the need for CO2,
GO! 1/2016
the main benefit of the method is that
it prevents swirling and foaming. As
a result, it now takes just one second
to fill a half-liter bottle, compared to
five seconds previously. That saves
customers time and money. ­Leibinger’s
method so impressed the indus­try
as a whole that the company was
awarded the German Innovation Prize
for Climate and Environment, sponsored by the German Federal Environment Ministry.
Tailored automation
The Balloon-Style plants are automated
by Simatic controllers and Comfort
Panels, configured and programmed
using the TIA Portal engineering framework. “The Basic controller, with its six
integrated high-speed counters, fits
optimally into our modular machine
set-up,” reports Christoph Mutschler,
Leibinger’s head of control and auto­
mation technology. Each S7-1200 CPU
controls six fill valves on the Leibinger
machines. Six magneto-inductive
­flowmeters measure the fill quantities.
They are connected to the six count
inputs of the PLC.
To fill the exact quantity, the fill valve’s
switching must be continually adapted
to the postflow quantity. Mutschler
explains: “Even minimal variations in
the fill valve settings would be imme-
diately noticeable by differing fill
levels in the bottles. That is why we
log the characteristic curves of every
bottling operation and continually
adapt the compensation.” The ser­
vice engineers are able to monitor
the enormous volumes of data this
creates on a PC via the integrated
web server of the Simatic S7-1200
controllers.
The S7-1200 controllers are connected
as I-Devices to the filling machine’s
central controller, a Simatic S7-1500,
via a slip ring. At this point, a CPU 1511
is sufficient for integration of the
drives and coordination of the sub­
ordinate Basic controllers. The central
controller also communicates with a
Simatic Comfort Panel for plant control
and monitoring.
High-efficiency engineering
Mutschler greatly appreciates the
­controllers’ new trace function for fine
adjustment of the fillers. “The flow
rate and pressure must be kept absolutely constant. The trace enables us
to remedy errors more quickly and
drive improvements more efficiently.”
For the Balloon-Style filler, Mutschler
for the first time made productive use
of the TIA Portal engineering platform.
His appraisal: being able to program
with Structured Control Language
(SCL) throughout has greatly improved
efficiency. “It allows programming
independently of the filling points.
The programs can be quickly and easily
upgraded to include the required
numbers of filling points. Changes
are made just once and automatically
applied to all filling points. The con­
sistently implemented symbolic access
makes doing all that much more
user-­friendly.”
High levels of user-friendliness
Leibinger places great value on the
high levels of user-friendliness of his
filling machines: “Our customers expect
that new technology can be applied by
the master brewer without need for
significant instruction. On the Simatic
Comfort Panels, we are able to implement clearly structured, easily understood operator interfaces, as well as
including additional guides – even in
video form. If required, we can also
log in to the customer’s plant remotely
from here via Sm@rtServer to assist
with diagnostics and maintenance after
the sale has been completed.”

Transparent energy flows for increased efficiency
Exact measurement of energy flows
is fundamental to any energy management system. The SM1238 AI Energy
Meter module for Simatic S7-1200 is
an ideal entry-level tool for machine-­
oriented energy management. It
records the electrical parameters in the
plant, such as overload, overvoltage or
undervoltage, and load voltage. The
measured values are processed directly
in the CPU. The module is just 45 mm
wide, making it extremely compact
and space saving in the control cabinet.
It also impresses with its low acquisition cost and large number of available
measurements.
The Energy Meter module enables
energy management based on more
than 40 energy measurement values.
The module records electrical mea­
surements in single- and three-phase
systems, and it can directly measure
voltages up to 480 V AC without a
transformer.
