LOGO! is ideally suited for implementing simple automation tasks in industry and building management systems.
The intelligent logic module is characterized by maximum user-friendliness and it leaves little to be desired in
terms of functionality, thanks in no small part to the high
memory capacity and efficient use of memory. With the
use of expansion modules, LOGO! can control even the
most complex plants without any problems.

that allow the constantly increasing requirements
to be quickly and economically fulfilled: Intelligent
solutions that stand out due to maximum flexibility,
reliability, and user-friendliness. The best example of
innovative technology that completely fulfills these
high requirements is LOGO! – the world‘s leading logic
module for switching and controlling.
Maximum flexibility due to consistent modularity
A wide range of modules make it possible to individually
expand LOGO! to 24 digital inputs, 16 digital outputs,
8 analog inputs, and two analog outputs. Communication modules for AS-Interface and KNX are also available.
With the analog output module, for example, you can
solve simple control tasks. This is supported by the special

Tried and tested millions of times –
in numerous applications
New applications made possible
by new 0BA7 basic units
In combination with the LOGO! software Soft Comfort,
the handling of our logic module is child’s play: Creating programs, project simulating and documentation
are quite easy using drag & drop – for maximum userfriendliness. In addition, a display with the capability of
directly changing process parameters in the message text
always ensures professional handling and satisfied users.
All of this is the reason why LOGO! has proven itself over
the past 15 years in millions of machine and building
appli­cations around the world.
The performance of LOGO! can be expanded in terms of
the number of I/Os and program capacity by means of
simple networking. It is not always necessary to switch
to more complex PLC configurations for simple networking requirements. Instead, you can remain in the familiar, simple configuration world of our logic module and
continue networking easily and cost-effectively. Even in
a single family home, there are so many possible applications that the number of I/Os is exceeded by a single
LOGO!. The simple networking via Ethernet is useful here.
The new communication options via Ethernet now allow
small LOGO! networks to be set up – as well as communication with higher-level systems.

Outstanding performance and overview
Highlights of LOGO!
With LOGO! four of the eight digital inputs that are available on the hardware can be used as analog inputs and
four as high-speed counter inputs up to a frequency of
5 kHz. With a program memory for 200 function blocks,
the 12/24 V DC devices provide sufficient capacity for
many stand-alone applications. Up to 50 four-line message
texts with a maximum of 32 characters per line ensure
user-friendliness in practice and clearly display all of the
relevant machine parameters. Well-conceived options such
as ticker text, bar graph or status parameter also contribute to the user-friendliness. Function blocks for arithmetic and pulse width modulation open up further usage
options. Last but not least: the Teleservice option, which
often does away with costly on-site service calls and really
pays off if you sell your systems cross-regionally.
■■Can be modularly expanded up to 50 I/Os
Additional text display
LOGO! allows an additional text display, which is perfectly
tailored to the needs of a logic module, to be connected.
It is directly connected to the LOGO! without a communication module. The configuration is done using the same
function block as for the internal display. You decide
whether message texts are displayed on the internal or
­external display – or on both.
■■230 V units can be expanded with analog modules
■■All three phases can be combined in a configuration
■■Extremely simple software
■■Display of up to 50 messages, either by LC display on
the module, external TD, or both together

LOGO! – and now also with Ethernet
LOGO! 0BA7 impressively proves that we are con­
stantly further developing our pioneering logic
module. The two new basic devices supplement the
existing 0BA6 basic devices, which have already
been tried and tested worldwide.
Proven devices have been consistently further
The developmental leap forward can even be seen on the
outside of our new LOGO! 0BA7 basic devices: They are
wider by two modular widths and the previous interface
has been replaced by an Ethernet interface on the underside of the device.
In addition, there is a slot for SD cards on the right front
of the device. In spite of these exterior changes, the new
devices are compatible with all existing I/O modules. Even
programs from the previous LOGO! generations can be
used in the new devices.
The highlight of the 0BA7 basic devices is without a doubt
the standard Ethernet interface. It is used as a programming interface and for communicating with other LOGO!
0BA7 basic devices or SIMATIC automation components
such as SIMATIC S7 CPUs, HMI Panels, and PCs. Up to
nine LOGO! devices can be networked via the Ethernet

New communication options
The networking is mainly used for direct communication between
several LOGO! devices. The advantages that result from this:
■■Increasing the number of I/Os in a configuration. One logic
module executes the program and the others only serve as an
I/O expansion – without processing their own program. This
means that a multi-cell layout in the control cabinet is now also
■■Expansion of the program memory. All logic modules process
their own program and only exchange some of the data among
each other.

A real highlight of the LOGO! 0BA7 generation are the
­different communication modes:
■■Communication between LOGO! and LOGO! – the
second LOGO! functions as an I/O expansion without
its own program.

LOGO! impresses customers due to the wide variety of possible
­applications and it allows the easy implementation of compre­hensive
applications – last but not least due to the possibility of selecting
from among 38 integrated functions and linking them to up to
200 blocks. When operating and monitoring, the 4-line backlit
­display with a maximum of 32 characters per line ensures a high
­degree of user-friendliness. The message text allows the display of
text, setpoints and actual values, bar graphs and status parameters.
Of course, parameters can be adjusted in the message text. ­
Flexibility is always assured due to the diverse expansion options.
... and the new ones with Ethernet
You have grown with LOGO! and you want to always be able to solve
more tasks with a greater demand on industrial communication?
Then, the new LOGO! 0BA7 devices are the ideal solution for you.
With the new basic devices, you can easily expand old programs
by adding functions.
Also possible: the supplementing of additional I/Os or the integration
of a user-friendly operator guidance via touch panels. Previously
developed LOGO! programs can be used as a basis and the easy
­configuration continues.

LOGO! 0BA7– more options in detail
With an Ethernet interface and SD card slot, LOGO!
Communication like never before
0BA7 opens up completely new perspectives – not only
Devices with an “E” in their names can communicate with
each other via Ethernet. This can happen in various ways:
in terms of communication capabilities. The standard
SD cards can be used – e.g. to copy programs or save
data/projects with comments. In addition, the program
memory has been expanded to 400 function blocks
and, in place of the optional battery, the internal
buffering of the real-time clock has been extended to
20 days.
■■Master/slave connections
between LOGO! and LOGO!
In this case, only one of a maximum of 9 basic devices processes a user program. The others only serve
to ­expand the I/O capacity. They provide the input
information of the digital and analog inputs to the first
LOGO! and execute the switching commands on the
other side for the digital outputs of their hardware, or
they forward the analog output values to the I/O. This
does away with the limitation on the number of channels of the previous basic devices. Of course, the basic
devices that are being used as slaves can be equipped
with the proven expansion modules up to the maximum process image.
■■Master/master connections
between LOGO! and LOGO!
In this mode, up to 9 basic devices can also be connected to each other. However, each LOGO! processes
its own program and shares only the generally needed
information with the others. In this way, small, networked systems with easy program structures can be
created. Each unit can continue to solve its subtask
without the others, if necessary.
In both cases, up to 9 basic devices and a PC/PG for
programming can be interconnected. The theoretical
degree of expansion of a LOGO! configuration is thus
88 DI, 80 DQ, 40 AI, and 18 AQ.
■■Communication with SIMATIC S7
The new LOGO! basic modules can be coupled to higherlevel automation structures (e.g. SIMATIC S7 CPUs or
HMI Panels with Ethernet interface), because they can
work with the standard S7 protocol. This allows, for
example, the use of SIMATIC Touch Panels for operating
a machine controlled by LOGO!. Of course, you can also
combine these communication options as needed.
Twice the program memory and
five new function blocks
The five new function blocks pay off in practice. Thus, for
example, minimum and maximum temperature values can
be determined over the course of a day or mean values
can be formed over a defined period of time. The duration
of any process can be measured using a stopwatch. In
­addition, there is an astronomical clock, which can be
used for such things as controlling outside lighting or
feeding times in animal husbandry, and an analog filter,
which helps to smooth the influence of interference
­pulses on the signal profile. Last but not least, the number
of usable shift registers has been increased to four. Thus,
shift registers with up to 32 bits are now possible.
Completely new perspectives
for communication,
data handling and storage
Increased engineering efficiency: reusable sections
of a program
More complex applications can be programmed using
LOGO! Soft Comfort V7 even easier than before: Macros
can now be used and libraries can be created for recurring
program sequences (e.g. for roller blind controllers).
­Corresponding program sections can then be selected
and reused at any time. When opening a program that
contains macros from the library, you are notified if the
macro has been changed since its last use. Macros are
also helpful when creating step sequence controls.
New usage options thanks to data logging
Thanks to data logging, you can now save specific pro­
duction or process data in a data area in the LOGO! –
­either by using the internal memory or by using a standard SD card up to 8 GB. This is advantageous if LOGO! is
used for controlling temperatures or monitoring levels,
for example. Corresponding characteristics can be easily
documented and evaluated. In the program, the user can
define the time intervals in which or the event by which
the temperature data or levels are to be recorded.
Simply more –
many more
­options in
­every respect
New advantages, old strengths
The status of the inputs and outputs are transferred to the
PC via the Ethernet interface and are documented there
in an Excel table, for example. However, the new software
also facilitates programming for users of the previous
LOGO!: Function blocks can be exchanged without having
to create new connections. The simplified handling includes additional capabilities for aligning the blocks and
the additional linking of comments.
Of course, the new generation of devices are also
­characterized by the proven strengths of LOGO!: from the
flexible, modular design and easy creation of programs,
project simulation and documentation by means of
drag & drop to the built-in display with HMI functionality.
The new basic devices are fully compatible with the old
ones, apart from the increased width of the devices
(108 mm instead of 72 mm), which is due to the implemented innovations. They have the built-in display, cursor
keys, and the familiar signal ports. Therefore, with their
expanded functionality, they can completely replace the
old 0BA6 basic devices.
In addition, all of the old expansion modules can be used
on the new basic devices without restrictions. The only
thing that must be noted is that an Ethernet cable is required in order to directly transfer an existing program
from one PC to one of the new basic devices.
