1 Getting started with LOGO!
Here’s LOGO!
LOGO! is a universal logic module made by Siemens.
LOGO! integrates
Controls
Operator and display panel with background lighting
Power supply
Interface for expansion modules
Interface for the program module (card) and a PC cable
Pre-configured standard functions, e.g. on- and
off-delays, pulse relay and softkey
Timer
Digital and analog flags
Inputs and outputs, according to the device type.
What LOGO! can do for you
LOGO! offers solutions for domestic and installation engineering (e.g. for stairway lighting, external lighting, sun
blinds, shutters, shop window lighting etc.), switch cabinet
engineering, as well as for mechanical and apparatus engineering (e.g. for gate control systems, air-conditioning systems, or rainwater pumps etc.).
LOGO! can also be implemented for special control systems in conservatories or greenhouses, for control signal
processing and, by connecting a communication module
(e.g. ASi) for distributed local controlling of machines and
processes.
Special versions without operator panel and display unit
are available for series production applications in small machine, apparatus, switching cabinet and installation engineering.

Getting started with LOGO!
The LOGO! system offers you many solutions such as for
small domestic installations, simple automation tasks, and
even complex engineering tasks involving its integration
into a bus system (e.g. communications module AS interface).
Note
LOGO! Basic may only be equipped with expansion modules of the same voltage class. Mechanical encoding pins
in the housing prevent you from connecting devices of a
different voltage class.
Exception: The left-hand interface of an analog module or
communication module is galvanically isolated.
This type of expansion module can therefore be connected
to devices of a different voltage class.
See also Chapter 2.1.
Each LOGO! Basic provides the following connections for
the creation of the circuit program, regardless of the number of connected modules:
Digital inputs I1 to I24
Analog inputs AI1 to AI8
Digital outputs Q1 to Q16
Analog outputs AQ1 and AQ2
Digital flag blocks M1 to M24, M8: Startup flag
Analog flag blocks AM1 to AM6
Shift register bits S1 to S8
4 cursor keys
16 blank outputs X1 to X16.

2 LOGO! installation and wiring
General guidelines
Please note the following guidelines for the installation and
wiring of your LOGO! :
Always ensure that the wiring of your LOGO! is compliant with current rules and standards. Also, conform
with all national and regional regulations when you
install and operate the devices. For information on standards and regulations that apply to your specific case,
contact your local authorities.
Always use cables with an appropriate conductor crosssections for the relevant current. You can wire the
LOGO! with cable conductor cross-sections from
1.5 mm2 to 2.5 mm2; see Chapter 2.3.
Do not exceed the screw torque of the terminals. The
maximum torque is: 0.5 N/m, see Chapter 2.3.
Keep the cabling as short as possible. If longer cables
are necessary, you should use shielded versions. You
should always route your cables in pairs: i.e. one neutral
conductor plus one phase conductor or signal line.
Always keep separate:
– The AC wiring
– High-voltage DC circuits with high-frequency switching cycles
– Low-voltage signal wiring.
Ensure that the wires are installed with an appropriate
strain relief.
Provide a suitable lightning surge arrester for cables
installed in relevant areas of hazard.

Take the quiescent current of any 2-wire proximity switches
used into account. The level of the quiescent current of
some 2-wire proximity switches is high enough to trigger a
logical ”1” signal at the LOGO! input. You should therefore
compare the quiescent current of the proximity switches
with the technical data of inputs Appendix A.

Restrictions
Signal status transitions 0 1 / 1 0
After a 0 to 1 or 1 to 0 transition, the signal must remain
constant at the input at least for the duration of one program cycle, so that LOGO! can detect the new signal status.
The program execution time is determined by the size of
the circuit program. Appendix B contains a benchmark test

Special features of LOGO! 12/24 RC/RCo and LOGO! 24/24o
High-speed inputs: I5 and I6
These versions are also equipped with high-speed counting
inputs (Up/down counters, Threshold triggers). The restrictions mentioned earlier do not apply to these high-speed
inputs.
Note
The high-speed inputs I5 and I6 are the same as in the
previous versions 0BA0 to 0BA3, i.e. a circuit program
that is written in these versions can be transferred to the
new 0BA4 units by means of the programming software
LOGO! SoftComfort, without any changes to these features. In contrast to this, you need to modify circuit programs written for a LOGO!...L version (high-speed inputs
I11/I12).
Expansion modules do not have high-speed inputs.
Analog inputs: I7 and I8
The inputs I7 and I8 of LOGO! versions 12/24RC/RCo and
24/24o can be used both as standard digital inputs and as
analog inputs. The input mode is defined in the LOGO! circuit program.
The inputs I7 / I8 provide digital functions, and the inputs
AI1 and AI2 provide analog functions.

You can connect either a 2- or 3-wire Pt100 resistive thermocouple to the module.
For a 2-wire connection, you need to short-circuit terminals
M1+ and IC1 or M2+ and IC2. Errors caused by the ohmic
resistance of the measuring line are not compensated with
this type of connection. A line resistance of 1 is proportional to a measuring error of +2.5°C.
A 3-wire technique suppresses the influence of the cable

You can also memorize four simple rules for starting
LOGO! :
1. If neither the LOGO! nor the inserted program module
(Card) contains a circuit program, the LOGO! (with display unit ) reports: ’No Program / Press ESC’.
2. A circuit program on the program module (Card) is automatically copied to LOGO!. The circuit program in the
LOGO! is overwritten.
3. If there is a circuit program in LOGO! or on the program
module (Card), LOGO! adopts the operational state it
had prior to POWER-OFF. Versions without display unit
(LOGO!...o) automatically change from STOP to RUN
(LED changes from red to green).
4. If you have enabled retentivity at least for one function,
or a function is permanently retentive, the current values
are retained at POWER-OFF.
Note
When a power failure occurs while you are entering a circuit program, the program in LOGO! will be deleted after
power is returned.
Before you modify the circuit program, you should therefore save a backup copy of your original to a program
module (Card) or to a computer (LOGO!Soft Comfort).

3 Programming LOGO!
Getting started with LOGO!
Programming in our context refers to the creation of a circuit program. A LOGO! circuit program program is actually
no more than a circuit diagram presented in a slightly different form!
We have adapted this presentation to the LOGO! display
field. In this chapter we are going to show you how to use
LOGO! to create the LOGO! circuit programs for your application.
At this point, we once again refer to LOGO!Soft Comfort,
which is the LOGO! programming software you can use to
quickly and easily create, test, modify save and print the
circuit programs. The topics in this manual relate only to
the creation of circuit programs on the actual LOGO!, because the programming software LOGO!Soft Comfort already contains an extensive Online Help.
See also Chapter 7.
Note
LOGO! versions without display unit, i.e. the LOGO! 24o,
LOGO! 12/24RCo, LOGO! 24RCo and LOGO! 230RCo
units, do not have an operator panel and display unit. They
are primarily designed for use in small machine and process equipment engineering systems for series production.
LOGO!...o versions are not programmed directly at the
unit. Instead, the circuit program is downloaded to this device by means of LOGO!Soft Comfort or program modules
(Cards) of other LOGO! 0BA4 units.
LOGO! versions without display can not write data to program modules (Cards).
See Chapter 6, 7 and Appendix C.

Programming LOGO!
A small example in the first part of this chapter introduces
the operating principle of LOGO!.
We shall first show you the meaning of two basic terms,
namely the connector and the block.
In the next step, we shall create a circuit program based
on a simple conventional circuit, which you ...
can enter directly in LOGO! in the third step.
It will take you only a few pages of this manual store your
first executable circuit program in the LOGO! unit. With a
suitable hardware (switches etc.), you will then be able to
carry out first tests.

Each output is identified by the letter Q plus a number. In
the figure, you can see the output terminals at the bottom.
LOGO! Manual
A5E00228550-01
39
Programming LOGO!
Note
LOGO! can recognize, read and switch the I/O of all expansion modules, regardless of their type. The I/O are presented in the installation order of the modules.
The following I/Os and flag blocks are available for the creation of your circuit program: : I1 to I24, AI1 to AI8, Q1 to
Q16, AQ1 and AQ2, M1 to M24 and AM1 to AM6. Also
available are the shift register bits S1 to S8, 4 cursor keys
C , C , C and C , as well as 16 blank outputs X1 to
X16. More details are found in Chapter 4.1.
The following applies to the inputs I7 and I8 of LOGO!
12/24... and LOGO! 24/24o versions: If Ix is used in the
circuit program, this input signal is digital; signals at AIx
are analog. Input AIx can only represent the connector that
is actually capable of handling analog signals.
LOGO!’s connectors
The term connector refers to all connections and states in
LOGO! .
The I/O status can be ’0’ or ’1’. Status ’0’ means that the
input does not carry a voltage. Status ’1’ means that the
input carries voltage.
We have introduced ’hi’, ’lo’ and ’x’ connectors to make it
easier for you to create the circuit program:
’hi’ (high) is assigned the status ’1’,
’lo’ (low) is assigned the status ’0’.
You do not have to use all the of connectors of a block. The
circuit program automatically assigns the unused connectors a status that ensures proper functioning of the relevant
block. If you prefer to do so, you can identify unused connectors with an ’x’.
For information on the meaning of the term “block”, refer to
Chapter 3.2.

3.2 Blocks and block numbers
This chapter shows you how to use LOGO! elements to
create complex circuits and how blocks and I/O are interconnected.
In Chapter 3.3 we are going to show you how to transform
a conventional circuit to obtain a LOGO! circuit program.
Blocks
A block in LOGO! represents a function that is used to convert input information into output information. Previously
you had to wire the individual elements in a control cabinet
or terminal box.
When you create the circuit program, you interconnect the
blocks. To do so, simply select the connection you require
from the Co menu The menu name Co is an abbreviation
of the term “Connector”.
Logic operations
The most elementary blocks are the logic operations:
AND
OR
...
I1
I2
x
x
1
Q
Inputs I1 and I2 are here connected
to the OR block. The last two inputs
of the block remain unused and are
identified be the creator of the circuit
program with an ’x’.
These special functions offer you a significantly higher performance:
Pulse relay
Up/down counter
On-delay
Softkey
....
In Chapter 4 you will find a full list of the LOGO! functions.

Programming LOGO!
The figure above shows you three views of the LOGO! display, which represent the circuit program. As you can see,
LOGO! interconnects the blocks using their numbers.
Advantages of the block numbers
You can connect almost any block to an input of the current
block by means of its block number. In this way, you can
reuse the interim results of logical or other operations, reduce programming effort, save memory space and clean
up your circuit layout. To do so, however, you need to know
how LOGO! has named the blocks.
Note
We advise you to create an organizational program chart.
You will find this a valuable help when you create the circuit program, because you can enter all block numbers
assigned by LOGO! in this chart.
By using the LOGO!Soft Comfort software to program the
LOGO!, you can directly create a function chart of your
circuit program. LOGO!Soft Comfort also allows you to assign 8-character names to up to 64 blocks, and to view
these on the LOGO! display in parameter assignment and
programming mode (see Chapter 3.4).

Note
Although you have four inputs available for logic operations (Basic functions, see Chapter 4.2), most of the views
will only show three inputs for reasons of clarity. You program this fourth input and assign parameters just like you
do with the other three inputs.
To create a circuit logic in LOGO!, start at the output.
The output is the load or relay that is to be switched.
Convert the circuit logic into blocks by working through the
circuit, starting at the output and ending at the input:
Step 1: The make contact S3 is interconnected in series to
output Q1 and to a further circuit element. A series connection corresponds with the AND block:

Step 2: S1 and S2 are connected in parallel. A parallel circuit corresponds with the OR block:

Unused inputs
The circuit program automatically assigns the unused connectors a status that ensures proper functioning of the relevant block. If you like, you can label unused connectors
with an ’x’ identifier.
In our example we shall use only two inputs of the OR
block and two inputs of the AND block; the relevant unused
third and fourth inputs are identified at the connector with
an ’x’.
Now connect the I/Os to the LOGO! .

3.4 The 4 Golden rules for the operation of
LOGO!
Rule 1
Changing the operating mode
You create the circuit program in programming mode.
After power is on, and when the display shows “No Program / Press ESC”, press the ESC key to select programming mode.
Timer and parameter values of an existing circuit program can be edited both in parameter assignment
mode and in programming mode. During parameter
assignment the LOGO! is in RUN mode, i.e. it continues execution of the circuit program (see Chapter 5). To
work in programming mode, you need to terminate the
circuit program by calling the “Stop” command.
Select the ’Start’ command on the main menu to set
RUN mode.
When the system is in RUN, you can return to parameter assignment mode by pressing the ESC key.
When parameter assignment mode is open and you
want to return to programming mode, select the
“Stop” command from the parameter assignment
menu, and confirm “Stop Prg” prompt with “Yes”. To
do so, move the cursor to “Yes” and confirm with OK.
For more details on operating modes, refer to Appendix D.
Note
The following applies to 0BA2 device versions and earlier:
You can open programming mode by pressing ++OK.
You set parameter assignment mode by pressing ESC+OK.
48
LOGO! Manual
A5E00228550-01
Programming LOGO!
Rule 2
Outputs and inputs
Always create your circuit program by working from the
output to the input.
You can connect an output to several inputs, but not the
same input to several outputs.
Within the same program path you may not connect an
output to an upstream input. For such internal recursions you should interconnect flags or outputs.
Rule 3
Cursor and cursor movement
The following applies when you edit a circuit program:
You can move the cursor when it appears in the form
of an underscore:
– Press , , or to move the cursor in the circuit
program.
– Press OK to change to ”Select connector/block”
– Press ESCto exit programming mode.
You select a connector/block
when the cursor appears as solid square
– Press or to select a connector or a block.
– Confirm with OK.
– Press ESC to return to the previous step.
Rule 4
Planning
Before you start to create a circuit program, you should
either first create design on paper or program LOGO!
directly using LOGO!Soft Comfort.
LOGO! can only save complete and faultless circuit programs.

What is meant by: ”LOGO! is in RUN”?
In RUN mode, LOGO! executes the circuit program. To do
so, LOGO! first reads the status at the inputs, determines
the status of the outputs by means of the user program,
and switches these on or off according to your settings.
This is how LOGO! indicates the I/O status:
Input/output status is ’1’:
inverted
Input/output status is ’0’:
not inverted

0.. 123456789
1..0123456789
2..01234
Q:
0.. 123456789

In this example, only the inputs I1, I15, Q8 and Q12 are set
“high“.

When switch S1 is closed,
the status at input I1 is hi.
LOGO! computes the output
states by means of the circuit program.
Output Q1 = ’1’, in this
case.
When Q1 = ’1’, LOGO! sets
relay Q1, and the load connected to Q1 is supplied
with voltage.

3.7 Memory space and circuit dimensions
The size of a circuit program in LOGO! is limited by the
memory space (memory used by the blocks).
Memory areas
Program memory:
LOGO! allows only a limited number of blocks in your
circuit program.
The second limitation is based on the maximum number
of bytes a circuit program may contain. The total number of bytes used can be determined by adding up the
number of bytes used for the relevant function blocks.
Retentive memory (Rem):
In this area, LOGO! stores process variables which
need to be retentive, e.g. the hours counter value.
Blocks with optional retentivity use this memory area
only if this function is actually enabled.
Resources available in LOGO!
A circuit program in LOGO! can occupy the following maximum resources:
Bytes
Blocks
REM
2000
130
60
LOGO! monitors memory utilization, and offers only those
functions from the lists for which it can actually provide sufficient memory space.

Utilization of memory areas
An indication of insufficient memory space is given, when
the system does not allow you to add a further block to
your circuit program. LOGO! offers you only the blocks for
which it can provide sufficient memory space. If LOGO! memory space is insufficient to hold any further blocks you
select from a block list, the system will deny access to this
list.
If memory space is fully occupied, optimize your circuit program, or install a second LOGO!.

Organization
LOGO! provides you with various elements in programming
mode. In order to maintain the overview, we have organized the elements in ’Lists’. These lists are:
Co: Connector list (Connector)
(see Chapter 4.1)
GF: List of the basic functions AND, OR, ...
(refer to Chapter 4.2)
SF: List of the special functions
(refer to Chapter 4.4)
BN: List of reusable blocks configured in the circuit
program
List contents
All lists show the elements available in LOGO!. Usually, this
includes all connectors, basic functions and special functions the LOGO! knows. This includes all the blocks you
have created in LOGO! by the time you call the BN list.
If not all is shown
LOGO! does not show all elements if:
No further blocks may be added.
This is either an indication of insufficient memory space
or that the maximum number of blocks has been
reached.
A specific block’s memory space requirement would exceed the space available in LOGO!.
See Chapter 3.7.
LOGO! Manual

LOGO! functions
4.1 Constants and connectors – Co
Constants and connectors (= Co) represent inputs, outputs,
flags and constant voltage levels (constants).
Inputs:
1) Digital inputs
Digital inputs are identified with an I. The number of the
digital inputs (I1, I2, ...) corresponds with the number of the
input connectors of the LOGO! Basic and of the connected
digital modules, in the order of their installation. See the
following figure.
2) Analog inputs
The LOGO! versions LOGO! 24, LOGO! 24o,
LOGO! 12/24RC and LOGO! 12/24RCo are equipped with
the inputs I7 and I8, which can also be programmed for use
as AI1 and AI2 inputs. Signals at the I7 and I8 inputs are
interpreted as digital values, and those at the AI1 and AI2
inputs are interpreted as analog values. The inputs of a
connected analog module are numbered according to the
already existing analog inputs. Special functions whose
inputs should only be connected to analog inputs are offered in programming mode when you select the input signal, i.e. the analog inputs AI1...AI8, analog flags
AM1...AM6, the block numbers of a function with analog
output or the analog outputs AQ1 and AQ2.
Outputs:
1) Digital outputs
Digital outputs are identified by the character Q. The output
numbers (Q1, Q2, ... Q16) correspond with the numbers of
the output connectors at the LOGO! Basic and with those
of the expansion modules, in their order of installation. See
the following figure.

LOGO! Manual
A5E00228550-01
LOGO! functions
There are also 16 blank outputs available. These are identified with an x and can not be reused in a circuit program (in
contrast to flags, for example). The list shows all programmed blank outputs, and one blank output which is not
yet configured. A blank output, for example, is useful for the
special function “Message texts” (see Chapter 4.4.23), if
only the message text is of significance to a circuit program.
2) Analog outputs
Analog outputs are identified by the letters AQ. Two analog
outputs are available, namely AQ1 and AQ2. You can only
set an analog value at the analog output, i.e. a function with
an analog output or analog flag AM.

Flag blocks
Flag blocks are identified by the letters M or AM . These
are virtual outputs, which output the value of their inputs.
LOGO! provides 24 digital flags M1 ... M24 and 6 analog
flags AM1 ... AM6.
LOGO! Manual
A5E00228550-01
91
LOGO! functions
Startup flag
Flag M8 is set in the first cycle of the user program and can
thus be used in your circuit program as startup flag. This
signal is automatically reset after the circuit program has
completed its first cycle.
The M8 flag can be used in all further cycles for setting,
deletion and evaluation procedures in the same way as
other flags.
Note
The output of the flag always carries the signal of the previous program cycle. This value does not change within
the same program cycle.
Shift register bits
LOGO! provides the shift register bits S1 to S8, which are
assigned the read-only attribute in the circuit program. The
content of shift register bits can only be modified by means
of the “Shift register” special function (see Chapter 4.4.25).
Cursor keys
Up to four cursor keys are available to you, namely C ,
C , C and C (”C” = “Cursor”). Cursor keys are programmed for the circuit program in the same ways as other
inputs. You can set the cursor keys in the corresponding
display while the system is in RUN (see Chapter 3.6.6),
and in an active message text (ESC + Key). Cursor keys
can save switches and inputs, and allow operator control of
the circuit program.
Levels
Voltage levels are designated hi and lo. A constant “1” = hi
or “0” = lo status at the block can be set by means of a permanent voltage level or constant value hi or lo.
Open connectors
Unused block connectors can be identified with an x.

4.2 Basic functions list – GF
Basic functions represent simple logical elements of Boolean algebra.
You can invert the inputs of individual basic functions , i.e.
the circuit program inverts a logical “1” at a relevant input to
a logical “0”; if “0” is set at the input, the program sets a
logical “1”. A programming example is found in
Chapter 3.6.3.
The GF list contains the basic function blocks you can use
for your circuit program. The following basic functions are

4.3 Basics on special functions
Because of their different input designation, you can see
right away that there is a difference between the special
functions and basic functions. SFs contain timer functions,
retentive functions and various parameter assignment options, which allow you to adapt the circuit program to suit
your own requirements.
This section provides you with a brief overview of input
designations and with some particular background information on SFs. The SFs in particular are described in
Chapter 4.4.

4.3.1 Designation of the inputs
Logical inputs
Here, you will find the description of the connectors you
can use to create a logical link to other blocks or to the inputs of the LOGO! unit.
S (Set):
A signal at input S sets the output to logical “1”.
R (Reset):
The reset input R takes priority over all other inputs and
resets the outputs.
Trg (Trigger):
This input is used to trigger the start of a function.
Cnt (Count):
This input is used for counting pulses.
Fre (Frequency):
Frequency signals to be evaluated are applied to this
input.
Dir (Direction):
This input determines the direction of count,
for example.
En (Enable):
This input enables a block function. When this input is
“0”, other signal from the block will be ignored.
Inv (Invert):
A signal at this input inverts the output signal of the
block.
Ral (Reset all):
All internal values are reset.
Connector X at SF inputs
SF inputs connected to connector x are set low. That is, the
inputs carry a ’lo’ signal.
LOGO! Manual
A5E00228550-01

LOGO! functions
Parameter inputs
At some of the inputs you do not apply any signals. You
configure the relevant block values instead. Examples:
Par (Parameter):
This input will not be connected. Here, you set the relevant block parameters (times, on/off thresholds etc.).
No (Cam):
This input will not be connected. Here, you configure the
time patterns.
P (Priority):
This is an open input. Here, you define priorities and

Time response
Parameter T
At some of the SFs it is possible to configure a time value
T. When you preset this time, note that your input values
are based on the timebase set:

Note
Always specify a time T in 0.02 s. The time T is not defined for T 0.02 s.

LOGO! Manual
A5E00228550-01
LOGO! functions
Accuracy of T
Because of slight tolerances in the characteristics of electronic components, the set time T may deviate. The LOGO!
has a maximum tolerance of 0.02 %.
When 0.02 % of the time T is smaller than 0.02 seconds,
the maximum deviation is 0.02 seconds.
Example:
The maximum tolerance per hour (3600 seconds) is
0.02 %, which is proportional to 0.72 seconds.
The maximum toloerance per minute (60 seconds) is
0.02 seconds.
Accuracy of the timer (weekly/yearly timer)
To prevent timing inaccuracy of the real-time clock in C versions caused by this deviation, the timer value is continuously compared with a high-precision timebase and corrected. The resultant maximum timing inaccuracy is 5
s/day.
4.3.3 Backup of the real-time clock
Because the internal real-time clock of a LOGO! is backed
up, it continues operation after a power failure. The ambient temperature influences the backup time. At an ambient
temperature of 25°C , the typical backup time is 80 hours.
4.3.4 Retentivity
The switching states and counter values of SFs can be set
retentive. This means that current data are retained after a
power failure, and that the block resumes operation at the
break point. The timer is not reset, but resumes operation
until the time-to-go has expired, for example.
To enable this response, however, the relevant functions
must be set retentive. Two options are available:
R: The data are retained.
/: Current data are not retained (default). See the example
on Page 72.
The hours counter forms an exception, because this function is always retentive.

4.3.5 Parameter protection
In the parameter protection settings, you can determine
whether the parameters can be displayed and edited in
LOGO! parameter assignment mode or not. Two options
are available:
+: The parameter attribute permits read/write access in parameter assignment mode (default).
–: The parameter settings are read/write protected in parameter assignment mode, and can be edited only in the
programming mode. See the example on Page 72.
4.3.6 Calculating the gain and offset of analog values
A sensor is connected to the analog input and converts a
process variable into an electrical signal. This value of signal lies within the typical range of this sensor.
LOGO! always converts the electrical signals at the analog
input into digital values from 0 to 1000.
A voltage of 0 to 10 V at input AI is transformed internally
into range of values from 0 to 1000. An input voltage exceeding 10 V is shown as internal value 1000.
Because you can not always process the range of values
from 0 to 1000 as predetermined by LOGO!, you can multiply the digital values by a gain factor and then shift the zero
of the range of values (offset). This allows you to output an
analog value to the LOGO! display, which is proportional to
the actual process variable.

LOGO! Manual

LOGO! functions
Mathematical rule
Actual value Ax =
(internal value at input Ax gain) + offset
Gain and offset calculation
The gain and offset is calculated based on the relevant high
and low values of the function.
Example 1:
The available thermocouples have the following technical
data: –30 to +70C, 0 to 10 V DC (i.e. 0 to 1000 in LOGO!).
Actual value = (internal value gain) + offset, thus
–30
= (0 A) + B, i.e. offset B = –30
+70
= (1000 A) –30, i.e. gain A = 0.1
Example 2:
A pressure sensor converts a pressure of 1000 mbar into a
voltage of 0 V, and a pressure of 5000 mbar into a voltage
of 10 V.
Actual value = (internal value gain) + offset, thus
1000
= (0 A) + B, i.e. offset B = 1000
5000
= (1000 A) +1000, i.e. gain A = 4

4.4 Special functions list – SF
When you create your circuit program in LOGO!, you find
the special function blocks in the SF list.
You can invert the inputs of SFs individually, i.e. the circuit
program converts a logical “1” at the input into a logical “0”;
a logical “0” it converts into a logical “1”. An example of the
program code found in Chapter 3.6.3.
The table also specifies whether the relevant function can

Each weekly timer has three cams you can use to configure a time hysteresis. You specify the on- and off-times at
the Cam parameters. The weekly timer sets the output at a
certain on-time, if this is not already set.
The weekly timer resets the output at a certain off-time, if it
is not switched off already. You will cause a conflict if the
on- and off-times you set for the weekly timer are identical,
though set on different cams. In this case, cam3 takes
priority over cam2, whereas cam2 takes priority over cam1.

Calculation rule
If the On threshold Off threshold, then:
Q = 1, if Cnt On
Q = 0, if Cnt < Off.
If the On threshold < Off threshold, then Q = 1,
if On Cnt < Off.
Default on/off parameters
The default limits for the on and/or off parameters can be
derived from another, already programmed function. You
can use the actual values of the following functions:
Analog comparator (actual value Ax – Ay,
see Chapter 4.4.18)
Analog threshold trigger (actual value Ax, see Chapter
4.4.16)
Analog amplifier (actual value Ax, see Chapter 4.4.20)
and
Up/down counter (actual value Cnt).
Select the required function by means of the block number.
For information on parameter defaults,
refer to Chapter 4.4.1.
Note
The system scans the counter limit value cyclically.
Thus, if the pulse frequency at the fast inputs I5/I6 is faster
than the cycle time, the special function might not switch
until after the specified limit value is exceeded.
Example: Up to 100 pulses per cycle can be counted; 900
pulses have been counted so far. On = 950; Off = 10000.
The output is set in the next cycle, after the value has
reached 1000. (The output would not be set at all if the
value Off = 980.)

Reducing the input response of the analog comparator
You can selectively delay the output of an analog comparator by means of the “On-delay” and “Off-delay” special
functions. With on-delay, output Q is only set if the pulse
width of the triggering signal at input Trg ( =analog
comparator output) is longer than the on-delay time. With
off-delay, output Q is only reset if the pulse width of the triggering signal at input Trg is longer than the off-delay time.
Using this method, you will obtain a virtual hysteresis and
reduce the input response to short signals.

Functional description
In parameter assignment mode, the output is set with a signal at input En, if the ’’Switch’ parameter is set to ’On’ and
confirmed with OK. Whether the function was configured
for pushbutton or switching action is here of no concern.
The output is reset to ’0’ in the following three cases:
After a 0 to 1 transition at input En.
When the function was configured for momentary pushbutton action, and one cycle has expired since it was
switched on.
When the position ’Off’ was selected at the ’Switch’ parameter and confirmed with OK in parameter assignment mode.
If retentivity is not set, output Q is initialized after a power
failure according to your configuration at the “Start” parameter.

Dir = 0: Shift up (S1 >> S8)
Dir = 1: Shift down (S8 >>
S1)
Parameter
Shift register bit that determines the value at output Q.
Possible settings:
S1 ... S8
Retentivity:
/ = No retentivity
R = The status is retentive.
Output Q

The output value corresponds with the configured
shift register bit.
LOGO! Manual
A5E00228550-01
LOGO! functions
Functional description
The function reads the value at input In with a positive edge
(0 to 1 transition) at input Trg (Trigger).
This value is applied to shift register bit S1 or S8, depending on the shifting direction:
Shift up: The value at input In is set at S1; the previous
value at S1 is shifted to S2; the previous value at S2 is
shifted to S3 etc.
Shift down: The value at input In is set at S8; the previous value at S8 is shifted to S7; the previous value at
S7 is shifted to S6 etc.
Output Q returns the value of the configured shift register
bit.
If retentivity is disabled, the shift function restarts at S1 or
S8 after a power failure. When enabled, retentivity always
applies to all shift register bits.
Note
The special function shift register can be used only once in
the circuit program.

5 Configuring LOGO!
When speaking of ’parameter assignment’, we refer to the
configuration of the block parameters. You can set delay
times for time functions, the switching times of the timers,
the counter threshold value, the monitoring interval of an
hours counter and the on and off thresholds of the trigger.
You can configure the parameters
In programming mode
In parameter assignment mode
In programming mode, the author of the circuit program
also sets the parameters.
We have added the parameter assignment mode to allow
the editing of parameters without having to modify the circuit program. This feature is available for the user to edit
parameters, without having to change to programming
mode, for example. The advantage: The circuit program
remains protected, but can be adapted by the user to meet
specific requirements.
Note
In parameter assignment mode, the LOGO! continues execution of the circuit program.

6 LOGO! program module (card)
LOGO! allows you to store only one circuit program in its
memory. If you want to modify the circuit program or create
a further one without deleting the first, you must archive it
somewhere. One of the options is to use a program module/card.
The circuit program stored in LOGO! can be copied to a
program module (card). You can then insert the program
module/card in another LOGO! to copy the circuit program.
using the program module (card), you can:
Archiving circuit programs
Reproducing circuit programs
Send circuit programs by mail
Write and test your circuit program at the office, and
then transfer it to a LOGO! in the switching cabinet.
LOGO! is supplied with a hood. The program module (card)
is supplied separately.
Note
You do not need a module to backup the circuit program in
your LOGO!.
The LOGO! circuit program is automatically stored in nonvolatile memory when you exit the programming mode.
We shall now introduce the program module (Card) you
can order for LOGO! The card can backup all data in the
LOGO! circuit program memory.
The order number is found in the appendix.

Compatibility
... to current versions (0BA4 devices):
Data written to the program module (card) in a 0BA4 version can be read in all other 0BA4 versions.
... to earlier versions (0BA0 to 0BA3 devices):
A program module (card) that contains data written in earlier versions (0BA0...0BA3 devices) can not be used in
LOGO! devices of the 0BA4 generation. When the LOGO!
system detects such an ’old’ program module (card), the
message “Unknown Card / Press ESC” is output to the display.
Vice versa, an 0BA4 program module (card) can not be
used in LOGO! devices of the 0BA0...0BA3 family.

6.1 Security function (CopyProtect)
We principally distinguish between program modules (card)
with and without circuit program/copy protection.
Unprotected program module (card)
You can edit circuit programs without restrictions, and exchange data between the program module (Card) and the
device.
Protected program module (card)
A circuit program is protected when it is transferred from a
protected program module (card) to the LOGO!.
To execute this circuit program in LOGO!, the protected
program module (card) must remain inserted during RUN,
i.e. the circuit program stored on the program module
(card) can not be copied to other LOGO! devices.
Over and above that, a protected circuit program is write–
protected.
A circuit program with password protection is no longer
protected after the correct password has been entered, i.e.
you can then edit the program and remove the module.
Note
You need to assign a password when you create the circuit
program for a protected module (card) to be able to edit it
at a later time (see Chapter 3.6.5).

Note
LOGO! applications are available to all our customers free
of charge. The examples provided are noncommittal, serve
as general information about the fields of application for
LOGO!, and may be different to user-specific solutions.
The user operates the system at his own responsibility. We
refer to the relevant national standards and system-related
installation regulations.
Although you have four inputs available for logic operations (basic functions, see Chapter 4.2), the following figures will only show a maximum of three inputs for reasons
of clarity. You program this fourth input and assign parameters just like the other three inputs.
Errors can not be ruled out, and the right to make changes
is reserved.

8.1 Stairway or corridor lighting
8.1.1 Requirements for a stairway lighting system
The basic requirements for a stairway lighting system are
as follows:
When someone is using the stairway, the lighting should
be switched on.
If no-one is in the stairway, the lights should be switched
off in order to save energy.
8.1.2 Previous solution
The two conventional options for switching the lights:
With a pulse relay
With an automatic stairway lighting switch
The wiring of both these lighting systems is identical.

Applications
Lighting system with pulse relay
Function of a lighting system with pulse relay:
Press any pushbutton: The lighting is switched on
Press any of the pushbuttons once again: The lighting is
switched off.
Disadvantage: People often forget to switch off the lights.
Lighting system with an automatic stairway lighting switch
Function of a lighting system with automatic stairway lighting switch:
Press any pushbutton: The lighting is switched on
The lights are switched off automatically when the preset time has expired.
Disadvantage: The lights can not be switched on for a longer period of time (e.g. when cleaning the stairway). The
switch for permanent lighting is usually located on the automatic stairway lighting switch and may be difficult or impossible to access.
8.1.3 Lighting system with LOGO!
A LOGO! system allows you to replace the automatic
stairway lighting switch or the pulse relay. You can also implement both functions (timed off-delay and pulse relay) in
a single unit. What is more, you can incorporate extra functions without making any alterations to the wiring. Here are
some examples:
Pulse relay with LOGO!
Automatic stairway lighting switch with LOGO!
Multiple function switch with LOGO!
– Switch light on
– Switch on permanent lighting
– Switch light off

be switched off automatically.
You can integrate various central functions:
– Central off
– Central on (panic button)
– Control of all lamps or individual circuits by means of
a daylight control switch
– Controlling by means of an integrated timer
(e.g. permanent lighting only until 24.00 h; disabled
at specific times)
– Automatically switching off the permanent lighting on
expiration of a preset time (e.g. after 3 hours)

8.3.2 Advantages of using LOGO!
The LOGO! solution requires less switchgear. That saves
you installation time and space in the control cabinet. You
might even be able to use a smaller switching cabinet.
Additional LOGO! options
The free output (Q4) can be used as isolated signal contact for reporting faults or power failure.
It is possible to switch off of the fans by means of a sequential circuit.
These functions can be implemented without additional
switchgear.

The entrance to a company’s premises is often closed with
a gate. The gate is only opened to let vehicles in and out.
The gate is controlled by the porter.
8.4.1 Requirements for a gate control system
The gate is opened and closed by means of pushbuttons in the gatehouse. The porter can monitor the operation of the gate at the same time.
The gate is normally fully opened or fully closed. The
gate motion can be interrupted at any time.
An indicator lamp is switched on five seconds before the
gate starts moving and when the gate is in motion.
A safety pressure bar prevents harm to persons and
objects from getting trapped or damaged when the gate
is closing.

Often, a company’s premises can be entered at several
locations. Not all of the gates can always be monitored locally by personnel. They must therefore be able to be monitored and operated by the porter who sits in a central gatehouse.
It must also be possible for a member of staff to open and
close the gate locally.
For each gate we are going to use one LOGO! 230RC and
one communication module AS interface. The modules and
the master are interconnected by means of a bus system.
This chapter describes a gate control system. The structures of the other gate control systems are identical.

When planning lighting systems for commercial locations,
the type and number of lamps used is determined by the
luminance required. For reasons of cost efficiency, the
installation often consists of fluorescent tubes arranged in
luminous rows, and are divided into separate switching circuits, according to the way the room is used.
8.6.1 Requirements for a lighting system
The various luminous rows are switched on and off locally.
If there is sufficient daylight, the rows on the window
side of the room are automatically switched off by
means of a daylight control switch.
The lights are switched off automatically at 20.00 h.
Local manual operation of the lighting must be possible
at all times.

The lamps are switched on and off with pulse relays, by
means of pushbutton control at the door. Regardless of
this, they are reset with a timer or daylight control switch
signal at the central off input. The pulse width of the off
commands must be reduced by means of wiping relays to
allow operation of the lights after they are switched off.
Components required:
Pushbuttons S1 to S4
Daylight control switch B1
Timer E1
Wiping relays K1 and K2
Pulse switches K3 to K6 with central OFF function
Disadvantages of the previous solution
A substantial amount of switchgear needs to be installed
to implement the necessary functions.
Due to the large number of mechanical components,
high wear and tear and maintenance expenditure is to
be expected.
The modification of functions involves considerable effort.

Advantages of the LOGO! solution
You can connect the lamps directly to the LOGO!, provided the power consumption does not exceed the
switching capacity of the various outputs. Higher loads
should be switched with a contactor relay.
Connect the daylight control switch directly to an input of
the LOGO! .
You do not need an external timer, because this function
is integrated in the LOGO! .
Due to the reduced amount of switchgear, you can
install a smaller and space-saving distribution cabinet.
Fewer devices are required
The lighting system can be easily modified.
Additional switching times can be set as required (sequential circuit for the off pulses at the end of the day).
The function of the daylight control switch can be easily
applied to all lamps or to a modified group of lamps.

8.7 Service water pump
The use of rainwater as an addition to the drinking water
supply is gaining importance in the domestic housing area.
This saves money and helps to protect the environment.
For example, rainwater can be used for:
Washing clothes
Irrigation system for gardens
Watering indoor plants
Car wash
Toilet flushing installations
The sketch below illustrates how such a rainwater utilization system is operated:

The rainwater is collected in a reservoir. From the reservoir,
a pumping station supplies a respective line system. From
there it can be tapped in the same way as normal drinking
water. If the reservoir should run dry it can be topped up
with drinking water.

8.7.1 Requirements for a control system of a service
water pump
Service water must be available at all times. In case of
emergency, the control system must automatically
switch over to drinking water supply.
When switching over to the drinking water supply, the
ingress of rainwater into the drinking water system must
be prevented.
The service water pump may not be switched on if the
reservoir has run low of rainwater (dry-run protection).

The pump and a solenoid valve are controlled by means of
a pressure switch and 3 float switches, which are installed
in the rainwater reservoir. The pump must be switched on
when the pressure level in the boiler drops below minimum.
After the operating pressure is reached, the pump is
switched off again after a tracking time of a few seconds
has expired. The tracking time prevents oscillation of the
water pump if water is drawn off over a longer period of
time.

Apart from the LOGO!, all you need is a pressure switch
and the float switches to control the pump. If you are using
a 3-phase AC motor, you must use a contactor relay to
switch the pump. For single-phase AC pump systems you
must provide a contactor relay if the power consumption of
the AC motor exceeds the capacity of the output relay Q1.
The power consumption of a solenoid valve is usually low
enough to allow direct controlling.

these *.pdf files with the Adobe AcrobatReader. If you have
installed LOGO!Soft Comfort on your computer, you can
simply click the disk icon to download the relevant circuit
programs, which you can then adapt to suit your application
and download to the LOGO! directly via the PC cable.
Benefits of LOGO!
LOGO! is a particularly useful feature
For replacing auxiliary switchgear with the integrated
LOGO! functions
For saving wiring and installation work - because
LOGO! keeps the wiring ”in its head”.
For reducing space requirements for components in the
control cabinet/distribution box. A smaller control cabinet/distribution box may provide sufficient space.
For adding or changing functions, without having to
install additional switchgear or change the wiring.
For offering your customers new, additional functions for
domestic and commercial housing installations. Examples:
– Domestic security systems: LOGO! switches on a
lamp at regular intervals or opens and closes the
shutters while you are on holiday.
– Central heating: LOGO! runs the circulation pump
only when water or heating is actually required.
– Refrigerating systems: LOGO! can defrost refrigerating systems at regular intervals to save energy costs.
– You can illuminate aquaria and terraria on a time-dependent basis.
Last not least you can:
Use commonly available switches and pushbuttons,
which makes it easy to install a domestic system.
Connect LOGO! directly to your domestic installation;
the integrated power supply makes it possible.

B Determining the cycle time
The program cycle is the complete execution of the circuit
program, that is, primarily the reading in of the inputs, the
processing of the circuit program and the subsequent reading out of the outputs. The cycle time is the time required to
execute a circuit program once in full.
The time required for a program cycle can be determined
using a short test program. This test program is created in
LOGO! and returns a value during its execution in parameter assignment mode from which the current cycle time is
derived.
Test program
1. Create the test program by linking an output to a threshold trigger and connecting the trigger input with an inverted flag.

Output Qx or
other flag Mx

2. Configure the threshold trigger as shown below. A pulse
is generated in each program cycle due to the inverted
flag. The trigger interval is set to 2 seconds.

3. Now start the circuit program and switch LOGO! to parameter assignment mode. In this mode, view the trigger
parameters.

On =1000
Off =0000
fa =0086
fa= total of measured pulses per timeba
4. The reciprocal value of fa is equivalent to the LOGO!
execution time of the current circuit program in its memory.
1/fa = cycle time in s
Explanation
The inverted flag block changes its output signal at each
program execution. Thus, one logic level (high or low) width
is exactly equivalent to the length of one cycle. Hence, a
period lasts 2 cycles.
The threshold trigger indicates the ratio of periods per 2
seconds, which results in the ratio of cycles per second.

each circuit program execution

Less is definitely more!
The versions without display offer you the following benefits:
Even more cost-effective without the operating element.
Requires less switch cabinet space than conventional
hardware.
Substantial benefits with regard to flexibility and prime
costs compared to stand-alone electronic switchgear.
Of advantage even for applications in which merely two
or three conventional switching devices can be replaced.
Very easy to use.
Access protected.
Compatible to LOGO! versions with display.
Offers the option to read data by means of LOGO!Soft

LOGO! without display
Creating a circuit program without operator panel
There are two ways to create a circuit program for a LOGO!
without display:
You create the circuit program with LOGO!Soft Comfort
on your PC and then download it to the LOGO!
(see Chapter 7).
You download the circuit program from a LOGO! program module (card) to your LOGO! without display
(see Chapter 6).
Operating characteristics
LOGO! is ready for operation when power is switched on.
Switching off a LOGO! without display is equivalent to disconnecting the power supply, e.g. as if you were removing
the plug.
The circuit program of LOGO!...o versions can not be started or stopped by means of buttons. This is why the
LOGO!...o versions have other startup characteristics:
Startup characteristics
If there is no circuit program in the LOGO! or on the inserted program module (card), LOGO! remains in STOP.
If there is a valid circuit program in LOGO! memory, the
LOGO! automatically switches from STOP to RUN when
power is switched on.
The circuit program on an inserted program module (card)
is automatically copied to the LOGO!, immediately after
power is switched on. The existing circuit program in
LOGO! memory is overwritten. The system automatically
changes from STOP to RUN.
Provided the PC cable is connected to the LOGO!, you can
download the circuit program to LOGO! and start it by
means of the LOGO!Soft Comfort PC software
(see Chapter 7.1).
286
LOGO! Manual
A5E00228550-01
LOGO! without display
Operating status indication
Operating states, e.g. Power On, RUN and STOP are indicated by an LED on the front hood.
Red LED:
Power On/STOP
Green LED:
Power On/RUN
The red LED is lit after Power On and in all LOGO! states
other than RUN. The green LED is lit when LOGO! is in
RUN mode.
Reading current data
LOGO!Soft Comfort (see Chapter 7) provides an online test
for reading the current data of all functions while the system is in RUN.
If your LOGO! without display holds a protected program
module (card), you can not read the current data unless
you enter the correct password for your the circuit program.
The circuit program is otherwise deleted from LOGO! memory when you remove the program module (card) to connect the PC cable, for example (see Chapter 6.1).
