include 0BA7 devices, SIMATIC S7 PLCs with Ethernet capability, and a SIMATIC HMI
that supports Ethernet communication with networked S7 PLCs. Additionally, a LOGO!
0BA7 can support a maximum of one Ethernet connection with a PC with LOGO!Soft
Comfort V7.0 installed.
● Use of Ethernet for LOGO! 0BA7 ↔ PC communication
Communication between a LOGO! 0BA7 and a PC takes place only on an Ethernet
network.
● SD card support
LOGO! 0BA7 supports standard SD (Secure Digital) cards that support FAT12, FAT16, or
FAT32 file system format. You can store and copy-protect a circuit program, with or
without the data log of process data, from a LOGO! 0BA7 to an SD card, or copy a circuit

Preface
● Support of configuration of elements connected to UDFs (User-Defined Functions)
LOGO!Soft Comfort V7.0 provides a new circuit program editor - the UDF editor. Circuit
programs created in the UDF editor can be saved as individual UDF blocks for use in an
existing or a new circuit program in LOGO!Soft Comfort. A UDF block is a preconfigured
circuit program that you create. If the circuit program in your LOGO! 0BA7 contains a
UDF block, you can edit the elements connected to this UDF block.
● Support of data logging
You can configure the Data Log function only from LOGO!Soft Comfort V7.0. The Data
Log is used to record actual values of digital and analog I/O, digital and analog flags, and
function blocks. If the circuit program in the LOGO! 0BA7 contains the Data Log block,
you can configure the elements connected to it from the LOGO! 0BA7. You can select to
store the data log either in the LOGO! 0BA7 or on an SD card. You can also save the
data log to a .CSV file on your PC and open it with Microsoft Excel or with a text editor.
● Extended real-time clock backup time
LOGO! 0BA7 has a built-in real-time clock that supports a typical backup time of 20 days.
● More connectors and memory space for the creation of the circuit program
Four new connectors that represent network digital inputs/outputs and network analog
inputs/outputs are available in a LOGO! 0BA7 if you have previously configured them
from LOGO!Soft Comfort V7.0. In addition, you can now have up to 16 analog flags, 64
open connectors, 32 shift register bits, and a maximum program memory of 8400 bytes
for up to 400 function blocks in you circuit program.
● New special function blocks
Five new special function blocks are available: Astronomical Clock, Stopwatch, Analog
Filter, Max/Min, and Average Value.
New features of the LOGO! 0BA6 device series
The following features were new for the LOGO! 0BA6 devices:
● A new expansion module named LOGO! AM2 RTD is commercially available. The
module is equipped with two analog inputs for connection to PT100 and/or PT1000
sensors with the default temperature coefficient of α = 0.003850 for both sensor types.
The LOGO! AM2 PT100 expansion module, however, only supports PT100 sensors.
● The LOGO! AM2 RTD module can automatically recognize the sensor type. It is thus
unnecessary for you to make any configuration or setting to achieve this.
● Two new LOGO! versions LOGO! 24C and LOGO! 24Co (each with a built-in real-time
clock) are commercially available.
● The LOGO! TD (Text Display) provides an additional display device for messages, and
contains four cursor keys and four functions keys that can be used in the circuit program.
● An additional password protection function is available in the LOGO! TD (version ES4 or
later) and can only be enabled when the LOGO! TD is used together with a LOGO! Base
Module (version ES4 or later).
● The new LOGO! Battery Card and the LOGO! Combined Memory/Battery Card provide
up to two years of backup time for the real–time clock. The new LOGO! Memory Card and
the Combined Memory/Battery Card provide 32 Kbytes memory space.

Features of the LOGO! TD
The LOGO! TD is available beginning with the 0BA6 series. It provides an additional display
that is wider than the LOGO! Basic. It has four function keys that you can program in your
circuit program as inputs. Like the LOGO! Basic, it has four cursor keys, an ESC key and an
OK key that you can also program in your circuit program and use for navigation on the
LOGO! TD.
You can create and download a power-up screen for the LOGO! TD from LOGO!Soft
Comfort. This screen displays briefly when you initially power on the LOGO! TD. You can
also upload the power-up screen from the LOGO! TD to LOGO!Soft Comfort.
The menus for the LOGO! TD are shown in Appendix section D.2. You configure the settings
for the LOGO! TD independently from the LOGO! Basic. The settings can be different.
Which communication modules are available?
● LOGO! communication module (CM) AS-Interface, which is described in more detail in a
separate documentation.
The communication module has four virtual inputs and outputs, and acts as an interface
between an AS-Interface system and a LOGO! system. The module enables four data
bits to be transferred from the LOGO! Base Module to the AS-Interface system and vice
versa.
● LOGO! communication module (CM) EIB/KNX, which is described in more detail in a
separate documentation.
CM EIB/KNX is a communication module (CM) for connecting the LOGO! to the EIB.
As an interface to EIB, CM EIB/KNX makes it possible to communicate with other EIB
devices. To do this, you store a configuration in the CM EIB/KNX that specifies the
inputs/outputs of the LOGO! to the EIB bus that are to be mapped. You can interconnect
the corresponding inputs/outputs using LOGO! functions.
It's your choice
The various LOGO! Base Modules, expansion modules, LOGO! TD and communication
modules offer you a highly flexible and adaptive system to suit your specific tasks.
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. communication module AS-Interface).

Note
The LOGO! Base Module 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 interface on the left side 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 (Page 36).
A LOGO! TD, if used, can be connected to only one LOGO! Base Module.
Each LOGO! Base Module supports 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 to AQ2
Digital flag blocks M1 to M27:
– M8: Startup flag
– M25: Backlight flag: LOGO! onboard display
– M26: Backlight flag: LOGO! TD
– M27: Message text character set flag
• Analog flag blocks: dependent upon the device series
– 0BA6: AM1 to AM6
– 0BA7: AM1 to AM16
• Shift register bits: dependent upon the device series
– 0BA6: S1 to S8
– 0BA7: S1.1 to S4.8 (32 shift register bits)
• 4 cursor keys
• Blank outputs: dependent upon the device series
– 0BA6: X1 to X16
– 0BA7: X1 to X64

General guidelines
Please note the following guidelines for installing and wiring 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 switch off power before you wire or install/remove a module.
● Always use cables with appropriate conductor cross-sections for the relevant current. You
can wire LOGO! with cable conductor cross-sections (Page 46) from 1.5 mm2 to 2.5 mm2.
● Do not exceed the screw torque of the terminals. The maximum torque is: 0.5 Nm.
● 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
– The EIB bus cable may also be laid in parallel to other signal lines
● Ensure that the wires are installed with appropriate strain relief.
● Provide a suitable lightning surge arrester for cables installed in hazardous areas.
● Do not connect an external power supply in parallel to the output load of a DC output.
This could develop a reverse current at the output if you have not installed a diode or
similar barrier device.
● Reliable functioning of the equipment is only ensured with certified components!
Note
LOGO! devices may only be installed and wired by skilled personnel who are familiar with
and follow general engineering rules and relevant regulations and standards.

LOGO! installation and wiring
What you must note when installing
LOGO! is designed for fixed and enclosed installation in the housing or the control cabinet.
WARNING
Attempts to install or wire LOGO! or related equipment with power applied could cause
electric shock or faulty operation of the equipment. Failure to disable all power to LOGO!
and related equipment during installation or removal procedures could result in death or
serious injury to personnel, and/or damage to equipment.
Always follow appropriate safety precautions and ensure that power to LOGO! is disabled
before attempting to install or remove LOGO! or related equipment.
Modules of a LOGO! are open facilities. This means that you must install LOGO! only in a
housing or cabinet.
Allow access to the housings or cabinets only with the use of a key or a tool and only by
authorized or approved personnel.
It is permissible to operate LOGO! from the front at any time.
Safety of electronic control equipment
Introduction
The notes below apply regardless of the type or manufacturer of the electronic control.
Reliability
Maximum reliability of LOGO! devices and components is achieved by implementing
extensive and cost-effective measures during development and manufacture.
This includes the following:
● Use of high-quality components
● Design of all circuits for worst-case scenarios
● Systematic and computer-aided testing of all components
● Burn-in of all large-scale integrated circuits (for example, processors, memory and so on)
● Prevention of static charge when handling MOS ICs
● Visual checks at different stages of manufacture
● Continuous heat-run test at elevated ambient temperature over a period of several days
● Careful computer-controlled final testing
● Statistical evaluation of all returned systems and components to enable the immediate
initiation of suitable corrective measures
● Monitoring of major control components, using online tests (cyclic interrupt for the CPU,
etc.)
These measures are referred to as basic measures.
LOGO!

Manual, 04/2011, A5E03556174-01
LOGO! installation and wiring
Carrying out tests
You must ensure safety in your plant.
Before finally commissioning a system, carry out complete functional testing as well as all
the necessary safety testing.
Also, test for any predictable faults that can occur. This means that you will avoid any danger
to the plant or to people during operation.
Risks
In all cases where the occurrence of failures can result in material damage or injury to
persons, take special measures to enhance the safety of the installation - and the
application. System-specific and special regulations exist for such applications. Follow these
regulations exactly when installing the control system (for example, VDE 0116 for burner
control systems).
For electronic control equipment with a safety function, the measures that you must take to
prevent or rectify faults are based on the risks involved in the installation. Beyond a certain
degree of hazard the basic measures mentioned above are not sufficient and you must take
additional safety measures for the controller.
Important information
Follow the instructions in the operating manual exactly. Incorrect handling can render
measures intended to prevent dangerous faults ineffective, or generate additional sources of
danger.

For LOGO! 12/24RCE, LOGO! 12/24 RC/RCo, LOGO! 24/24o, LOGO! 24C/24Co modules,
you can configure whether the module uses two or four of the four possible analog inputs. AI
inputs are numbered consecutively depending on how many you configure the LOGO! Base
Module to use. If you configure two inputs, they are numbered AI1 and AI2, and correspond
to the I7 and I8 input terminals. Subsequent AI expansions modules would begin numbering
at AI3. If you configure four inputs, they are numbered AI1, AI2, AI3, and AI4, and
correspond to I7, I8, I1, and I2 in that order. Subsequent AI expansions modules would begin
numbering at AI5. See topics "Constants and connectors - Co (Page 138)" and "Setting the
number of AIs in the LOGO! Basic (Page 299)".

2.1 Modular LOGO! setup
High-speed/optimal communication performance
For optimal and high-speed communication performance between the LOGO! Base Module
and the various modules, we recommend that you install the digital modules first, then the
analog modules (examples above). (The special function PI controller is an exception: the AI
used for the value PV should be on the LOGO! Base Module or an analog input module
adjacent to the LOGO! Base Module).
Siemens recommends that you position the CM AS Interface on the far right. (If the AS
Interface voltage fails, communication between the LOGO! system and expansion modules
that are arranged to the right of the LOGO! CM AS Interface expansion module is
interrupted).
The LOGO! TD module is installed separately. You connect it to the LOGO! Base Module
with the included LOGO! TD cable.
Note
CM EIB/KNX must always be installed as the last module on the right of LOGO!.
No further interface modules may be connected to the CM EIB/KNX.

Setup with different voltage classes
Rules
Digital modules can only be directly connected to devices of the same voltage class.
You can connect analog and communication modules to devices of any voltage class.
You can replace two similar DM8 expansion modules by one appropriate DM16 expansion
module (and vice versa) without having to change the circuit program.
Note
Two DM8 12/24R can be replaced by one DM16 24R only if operated with a power supply of
24 V DC.
Two DM8 24R can be replaced by one DM16 24R only if operated with DC and P action.

2.3.1
Connecting the power supply
The 230-V versions of LOGO! are suitable for operation with rated voltages of 115 V AC/DC
and 240 V AC/DC. The LOGO! 24-V and 12-V versions can be operated with a 24 VDC, 24
V AC or 12 V DC power supply. For information on permissible voltage tolerances, line
frequencies and power consumption, refer to the installation instructions in the Product
Information supplied with your device and to the technical data in Appendix A.
The CM EIB/KNX has been designed as a communication module for the LOGO! controller
and must be supplied with a mains voltage of 24 V AC/DC.
The AS Interface bus requires a special AS Interface power supply (30 V DC) that enables
simultaneous transmission of data and power for the encoders via a single line.
The LOGO! TD must be supplied with a voltage of 12 V DC or 24 V AC/DC.
CAUTION
Expansion modules DM8 230R and DM16 230R must be operated with the same type of
power supply (DC or AC) as for the connected 230-V version of the LOGO! Base Module.
The same supply output "+/- "on DC power supplies or "N/L" on AC power supplies must
connect to the same phase on both the expansion module DM8/16 230R and the
connected LOGO! 230 .... Failure to follow the instructions could result in personal injury.
Note
A power failure might cause an additional edge triggering signal at the special functions. The
stored data will be from the last uninterrupted cycle.

Connecting glow lamps and 2-wire proximity switches (Bero) to LOGO!
230RCE/230RC/230RCo or LOGO! DM8 230R (AC) and LOGO! DM16 230R (AC)
The figure below shows how you connect a switch with a glow lamp to LOGO! The current
that flows through the glow lamp allows LOGO! to detect a "1" signal even though the switch
contact is not closed. If, however, you use a switch the glow lamp of which is fitted with a
power supply, this response does not occur.

/

,
,
,
,
;FDSDFLWRUN9Q)
Take into account the quiescent current of any 2-wire proximity switches used. 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 (Page 319).
Remedy
To suppress this response, use an X capacitor rated at 100 nF and 2.5 kV. In a destructive
situation, this type of capacitor safely disconnects. You must choose the voltage level for
which the capacitor is rated such that it is not destroyed in the case of overvoltage!
At 230 V AC, the voltage between N and an input I(n) must not be greater than 40 V to
guarantee a "0" signal. You can connect approximately ten glow lamps to the capacitor.
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. The appendix
"Determining the cycle time (Page 349)" contains a benchmark test routine that you can use
to determine the current scan cycle time.

Special features of LOGO! 12/24RCE/RC/RCo, LOGO! 24/24o and LOGO! 24C/24Co
Fast digital inputs: I3, I4, I5 and I6:
These versions are also equipped with fast digital inputs (up/down counters, threshold
triggers). The restrictions mentioned earlier do not apply to these fast digital inputs.
Note
The fast digital inputs I3, I4, I5 and I6 are the same as in the previous versions 0BA0 to
0BA5; therefore, a circuit program that is written in these versions can be transferred to the
0BA6 or 0BA7 devices with the programming software LOGO!Soft Comfort, without any
changes to these features. In contrast to this, you need to modify circuit programs written for
a LOGO!...L version (fast digital inputs I11-I12). The fast digital inputs have increased from 2
kHz to 5 kHz with the 0BA6 series.
Expansion modules do not have fast digital inputs.
Analog inputs: I1 and I2, I7 and I8:
The inputs I1, I2, I7 and I8 of LOGO! versions 12/24RCE/RC/RCo, 24/24o and 24C/24Co
can be used as either digital inputs or analog inputs. The input mode is defined in the LOGO!
circuit program.
The inputs I1, I2, I7 and I8 provide digital inputs, and the inputs AI3, AI4, AI1 and AI2 provide
analog inputs, as described in the topic "Constants and connectors - Co (Page 138)". AI3
corresponds to the input terminal I1; AI4 corresponds to I2; AI1 corresponds to I7; AI2
corresponds to I8. The use of AI3 and AI4 is optional. You configure your LOGO! to use
either two or four analog inputs as described in topic "Setting the number of AIs in the
LOGO! Basic (Page 299)" in Section 5.2.4.
When using inputs I1, I2, I7 and I8 as analog inputs, only the range from 0 to 10 V DC is
available.
Connecting a potentiometer to inputs I1, I2, I7 and I8
To allow you to achieve 10 V as the maximum value when you completely turn the
potentiometer once, you must connect a series resistor on the potentiometer's input side
regardless of the input voltage (see figure below).
We suggest the following sizes of potentiometers and associated series resistors:
Voltage
Potentiometer
Series Resistor
12 V
5 kΩ
-
24 V
5kΩ
6.6 k Ω
When using a potentiometer and 10 V input voltage as the maximum value, you must ensure
that with a connected input voltage of 24 V, 14 V must release via the series resistor so that
a maximum of 10 V are supplied when you turn the potentiometer one full rotation. With a
voltage of 12 V, this can be neglected.
Note
The LOGO! AM2 expansion module provides additional analog inputs. The LOGO! AM2
PT100 expansion module provides PT100 inputs.
Always use twisted and shielded cables for analog signals, and keep these as short as
possible.

The illustration above shows an example of four-wire current measurement and two-wire
voltage measurement.
Connecting a two-wire sensor to the LOGO! AM2
Wire up the two-wire sensor's connecting wires as follows:
1. Connect the sensor's output to connection U (0 ... 10 V voltage measurement) or to
connection I (0/4 ... 20 mA current measurement) of the AM2 module.
2. Connect the plus connector on the sensor to the 24 V supply voltage (L+).
3. Connect the ground connection of the current output M (on the right side of the sensor, as
shown in the figure above) to the corresponding M input (M1 or M2) on the AM2 module.

You can connect a maximum of two 2-wire or 3-wire PT100 sensors or one 2-wire plus one
3-wire PT100 sensor to the module. Note that the sensor type supported by the module is
only PT100 with the default temperature coefficient of α= 0.003850.
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 for this
type of connection. A line resistance of 1 Ω is proportional to measuring error of +2.5 °C.
A 3-wire technique suppresses the influence of the cable length (ohmic resistance) on the
result of the measurement.

Note
Fluctuating analog values are due to screening on the connecting wire from the analog
valuator device to the analog AM2 / AM2 PT100 / AM2 RTD LOGO! expansion module
(encoder wire) that has either been mounted incorrectly or not at all.
To avoid fluctuating analog values when using these expansion modules, proceed as
follows:
• Use only shielded encoder wires.
• Shorten the encoder wire as much a possible. The encoder wire must not be more than
10 meters long.
• Clamp the encoder wire on one side only and clamp it only to the PE terminal on the AM2
/ AM2 PT100 / AM2 AQ / AM2 RTD expansion module.
• Connect ground on the encoder supply to the PE terminal on the expansion module.
• Avoid operating the LOGO! AM2 PT100 or LOGO! AM2 RTD expansion module with a
power supply that is not grounded (potential-free). If you cannot avoid this, connect the
negative output/ground output on the power supply to the shielding on the resistance
thermometer's measuring wires.

Connecting the AS interface bus
To set the address of the module on the AS interface bus, you need an addressing unit.
Valid addresses are in the range of 1 to 31. Use each address once only.
You can set the address on the AS interface bus before or after installation.
If the installed module is addressed via the address socket, the AS-Interface voltage must be
disconnected beforehand. This is necessary for safety reasons.

Networking on the AS interface bus
To make the connection to the AS interface bus, you need a communications-capable
LOGO! variant:
● LOGO! Base Module + CM AS-I.
To be able to send data across the AS interface bus to LOGO! and to receive data from it in
the same way, you also need:
● an AS interface power supply and
● an AS interface master (e.g. an S7-200 with a CP243-2 or a DP/AS-I Link 20 E).
LOGO! can only be accepted as a slave on the AS interface bus. This means that it is not
possible to directly exchange data between two LOGO! devices. Data is always exchanged
across the AS interface master.
WARNING
The AS-Interface and LOGO! systems must never be connected together electrically!
Use safe isolation according to IEC 61131-2, EN 50178, UL 508, CSA C22.2 No. 42.

Switching the LOGO!/Power On
LOGO! does not have a power switch. The reaction of LOGO! during startup depends on the
following:
● Whether a circuit program is stored in LOGO!
● Whether a card is inserted (The card can be a LOGO! memory card, combined
memory/battery card, or SD card for a LOGO! 0BA7.)
● Whether this is a LOGO! version without display unit (LOGO!...o)
● The status of LOGO! at the time of power failure.
To ensure that the expansion module on LOGO! changes to RUN mode, check the following:
● Has the sliding contact between LOGO! and the expansion module snapped into place
properly?
● Is the power supply connected to the expansion module?
● In addition, always ensure that you switch on the power supply to the expansion module
first before activating the power supply to the LOGO! Base Module (or activate both
power supplies at the same time); if you do not do this, the system does not detect the
expansion module when you start up the LOGO! Base Module.

2. A circuit program on the card is automatically copied to LOGO!. The circuit program in
LOGO! is overwritten.
3. If there is a circuit program in LOGO! or on the card, LOGO! adopts the operational state
it had prior to POWER-OFF. Versions without a display unit (LOGO!...o) automatically
change from STOP to RUN (LED changes from red to green).
4. If you have enabled retentivity for at least 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!
is deleted after power is returned.
Before you modify the circuit program, save a backup copy of your original to a card or to a
computer, using LOGO!Soft Comfort.

Getting started with LOGO!
Programming refers to creating a circuit program from the LOGO! Base Module.
In this chapter you will learn how to use LOGO! to create the LOGO! circuit programs for
your application.
LOGO!Soft Comfort is the LOGO! programming software that you can use on your PC to
quickly and easily create, test, modify, save and print the circuit programs. The topics in this
manual, however, relate only to the creation of circuit programs on the actual LOGO! Base
Module. The programming software LOGO! Soft Comfort contains extensive online help.
Note
LOGO! versions without a display unit, that is, the LOGO! 24o, LOGO! 24Co, LOGO!
12/24RCo, LOGO! 24RCo and LOGO! 230RCo versions, 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 on the device. Instead, the circuit program
is downloaded to the device from LOGO!Soft Comfort or from memory cards or combined
memory/battery cards from other LOGO! devices.
LOGO! versions without a display cannot write data to memory cards or combined
memory/battery cards.
See the chapters "Applicable cards (Page 303)", "LOGO! software (Page 313)" and the
appendix "LOGO! without display ("LOGO! Pure") (Page 351)" for more information.
A small example in the first part of this chapter introduces the operating principles of LOGO!:
● You will learn the meaning of two basic terms, namely the connector and the block.
● As the next step, you will create a circuit program based on a simple conventional circuit.
● Lastly, you will enter this program directly in LOGO!
It will take you only a few pages of this manual to store your first executable circuit program
in the LOGO! unit. With suitable hardware (switches etc.), you will then be able to carry out
initial tests.

3.1 Connectors
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.
Dependent upon specific LOGO! device series, the following I/O and flag blocks are
available for creating your circuit program from LOGO!:
• LOGO! 0BA6
I1 to I24, AI1 to AI8, Q1 to Q16, AQ1 and AQ2, M1 to M27, and AM1 to AM6. Also available
are the shift register bits S1 to S8, 4 cursor keys C , C , C and C , four function keys
on the LOGO! TD: F1, F2, F3, and F4 as well as 16 blank outputs X1 to X16.
• LOGO! 0BA7
I1 to I24, AI1 to AI8, Q1 to Q16, AQ1 and AQ2, M1 to M27, and AM1 to AM16. Also available
are 32 shift register bits S1.1 to S4.8, 4 cursor keys C , C , C and C , four function
keys on the LOGO! TD: F1, F2, F3, and F4, as well as 64 blank outputs X1 to X64. If you
have previously configured any of the network digital or analog inputs/outputs NI1 to NI64,
NAI1 to NAI32, NQ1 to NQ64, and NAQ1 to NAQ16 in your circuit program from LOGO!Soft
Comfort, after downloading the circuit program to LOGO!, these network digital or analog
inputs/outputs are available in the LOGO!; however, you can not edit the rest of the program
from the LOGO!, except for the Par parameter.
See the "Constants and connectors (Page 138)" topic for more details.
The following applies to inputs I1, I2, I7 and I8 of LOGO! 12/24..., LOGO! 24/24o and LOGO!
24C/24Co versions: If you use I1, I2, I7 or I8 in the circuit program, this input signal is digital.
If you use AI3, AI4, AI1, or AI2, the input signal is analog. The numbering of the analog
inputs is significant: AI1 and AI2 corresponded to I7 and I8 on the 0BA5 module. With the
addition of two new analog inputs for the device series 0BA6 and 0BA7, these modules
optionally use I1 for AI3 and I2 for AI4. See the graphical representation in the topic on
"Maximum setup with expansion and communication modules (Page 34)". Also note that you
can also use I3, I4, I5, and I6 as fast digital inputs.
The illustration above with numbered AI inputs shows the conceptual usage of the inputs, not
the actual physical markings on the module.
LOGO!'s connectors
The term connector refers to all connections and states in LOGO! .
The digital I/O status can be '0' or '1'. Status '0' means that the input does not carry a specific
voltage. Status '1' means that the input does carry a specific voltage.
The 'hi', 'lo' and 'x' connectors have been introduced 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 of the 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 the topic on "Blocks and block
numbers (Page 74)".

3.2 EIB inputs/outputs
3.2
EIB inputs/outputs
The application program "20 CO LOGO! 900E02" controls the communication between the
LOGO! and the EIB/KNX bus via the communication module CM EIB/KNX.
By configuring the application program in ETS (EIB Tool Software), the division of the input
and output area of the LOGO! can be defined as a "hardware channel" and as a "virtual
channel" on the EIB/KNX bus.
This characteristic also applies for analog processing.
A communication object is assigned to each "hardware channel" and each "virtual channel"
of LOGO! module.
The real-time clock of LOGO! can be used as a master or slave via the EIB/KNX bus.
The behavior of the communication objects of the communication module CM EIB/KNX,
when the status of the EIB/KNX bus changes, can also be parameterised.
A "virtual input channel" can be used as a bus state; that is, a bus voltage failure can be
reported.
The settings for analog values in LOGO! (Offset, Gain) do not affect the analog values for
the CM EIB/KNX communication module (the output values of the CM EIB/KNX are always
the raw values between 0 and 1000). In this case, you must parameterize customizing in the
ETS.
Functions of the application program
● Specification of the hardware configuration (number of local digital inputs and outputs,
analog inputs)
● Selection of time master or slave
● Use of I24 as a bus status signal
● Behavior on bus voltage failure/recovery
● Input type as monoflop/normal for digital inputs via the EIB/KNX
● Output type as normal/dimmer/edge evaluation for digital outputs via the EIB/KNX
● Data type, adaptation, cyclical sending and sending on change in value for analog
outputs via the EIB/KNX and analog inputs on LOGO!
Any further details about configuring the application program in ETS can be found in the
current application program description.

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 the topic "From circuit diagram to LOGO! Program (Page 76)" you will learn how to
transform a conventional circuit into 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

Advantages of 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
An organizational program chart can be a valuable aid when you create the circuit program
because you can enter in this chart all the block numbers that LOGO! assigns.
By using the LOGO!Soft Comfort software to program LOGO!, you can directly create a
function chart of your circuit program. LOGO!Soft Comfort also allows you to assign eightcharacter names to up to 100 blocks, and to view these on the LOGO! onboard display in
parameter assignment mode. See the topic "The four golden rules for operating LOGO!

3.4 From circuit diagram to LOGO! program
Note
Although you have four inputs available for logic operations (Page 142), 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 circuit 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:
,
4
[
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/O to LOGO! .
Wiring
Connect the switches S1 to S3 to the screw terminals of your LOGO! :
● S1 to connector I1 of LOGO!
● S2 to connector I2 of LOGO!
● S3 to connector I3 of LOGO!
The output of the AND block controls the relay at output Q1. The load E1 is connected to
output Q1.

3.5 The four golden rules for operating LOGO!
3.5
The four golden rules for operating 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
LOGO! is in RUN mode; that is, it continues executing the circuit program (see the topic
"Configuring LOGO! (Page 287)"). 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 the Appendix topic "LOGO! Menu structure
(Page 353)".
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.
Rule 2: Outputs and inputs
● Always create your circuit program by working from the output to the input.
● You can connect an input to several outputs, but not the same output to several inputs.
● 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.

3.5 The four golden rules for operating LOGO!
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 ESC to exit programming mode.
● You select a connector/block - when the cursor appears as a 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 a design on
paper or program LOGO! directly using LOGO!Soft Comfort.
● LOGO! can only save complete and faultless circuit programs.

Your circuit program is now named "ABC", and you are returned to the programming menu.
To change the name of your circuit program, proceed in the same way.
Note
You can change the name of the circuit program only in programming mode. You can read
the name both in programming and in parameter assignment mode.
3.7.5
Password for circuit program protection
You can protect a circuit program from unauthorized access by assigning it a password.
You can only assign or deactivate a program password from a LOGO! Basic or from
LOGO!Soft Comfort. You can only change a program password from a LOGO! Basic. If you
have assigned a program password, and are using a LOGO! TD (version ES4 or later)
together with a LOGO! Base Module (version ES4 or later), you must enter this password if
you want to change LOGO! from RUN mode to STOP mode from the LOGO! TD. You can
not stop the execution of the circuit program in LOGO! from the LOGO! TD without entering
the password.
Note
This password protection function is only available in the LOGO! TD with version number
ES4 or later. This function is only available under the following conditions:
• The version number of both the LOGO! Base Module and the LOGO! TD installed is at
least ES4
• LOGO! is currently in RUN mode and you want to switch to STOP mode
There is only one circuit program protection password that you can assign for LOGO!. You
can only assign it from the LOGO! Basic or from LOGO!Soft Comfort. To change LOGO!
from RUN to STOP from the LOGO! TD, you must enter the password from the LOGO! TD
as described below in the section "Changing LOGO! from RUN to STOP mode from the
LOGO! TD".
LOGO! 0BA7 provides an additional password menu command for your changing LOGO!'s
communication mode from normal (client/server) mode to slave mode or vice versa.

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 circuit program, and
switches these on or off according to your settings.
This is how LOGO! indicates the I/O status:

The B1 block previously connected to Q1 is automatically connected to the uppermost input
of the new block. Note that you can only interconnect digital inputs with digital outputs or
analog inputs with analog outputs. The 'old' block will otherwise be lost.
The off-delay block has three inputs. At the top is the trigger input (Trg) you use to start the
off-delay time. In our example, the OR block B1 triggers the off-delay. You reset the time and
the output with a signal at the reset input. Set the off-delay time at parameter T of the input

Changing LOGO! to normal/slave mode
LOGO! 0BA7 provides a menu command for network communication settings. The section
Configuring network settings (Page 119) showed you how to configure the network IP
address, subnet mask and gateway for your LOGO!. This section shows you how to change
LOGO!'s network communication mode.
A LOGO! 0BA7 device works in either normal or slave communication mode.
Normal mode versus slave mode
A LOGO! 0BA7 in normal mode supports client-server communication with SIMATIC S7
PLCs, a SIMATIC HMI or other 0BA7 devices across Ethernet. This LOGO! can additionally
act as a master to communicate with one or more 0BA7 devices in slave mode.
A LOGO! in slave mode functions as a LOGO! expansion module. No circuit program is
required for slave LOGO! devices. A master LOGO! can read one or more slave LOGO!'s
digital/ analog input values and write its own digital/analog output values to these slaves.
This helps LOGO! achieve network I/O expansion.
Note
A LOGO! in slave mode can also have its own expansion modules. It also supports a
maximum of 24 digital inputs, 8 analog inputs, 16 digital outputs and 2 analog outputs.

Memory space and circuit program size
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 values which need to be retentive; for example, the hours
counter value. Blocks with optional retentivity use this memory area only if this function is
actually enabled.
Note
LOGO! supports a maximum of one million write cycles. LOGO! counts every power-off,
program downloading from LOGO!Soft Comfort to LOGO!, program creation from LOGO!,
or menu setting as one cycle.
Resources available in LOGO!
A circuit program in LOGO! can occupy the following maximum resources:

Note
Since a UDF block is a preconfigured circuit program that you create from LOGO!Soft
Comfort V7.0 for your LOGO! 0BA7 device, the memory size (program memory and Rem
memory) of a UDF block depends upon the size of the function blocks contained in the UDF.
Utilization of memory areas
The system indicates that there is insufficient memory space by not allowing you to add a
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 additional
blocks, the system will deny access to the block list.
If memory space is fully occupied, optimize your circuit program or install another LOGO!.

4.1 Constants and connectors - Co
4.1
Constants and connectors - Co
Constants and connectors (Co) represent inputs, outputs, flags, constant voltage levels
(constants), and network digital and analog inputs/outputs (if 0BA7).
Inputs:
1) Digital inputs
Digital inputs are identified with an I. The number of the digital inputs (I1, I2, ...) corresponds
to the number of the input connectors of the LOGO! Base Module and of the connected
digital modules, in the order of their installation. The fast digital inputs I3, I4, I5, and I6 of the
LOGO! versions LOGO! 24/24o, LOGO! 24C/24Co, LOGO! 12/24RC, LOGO! 12/24RCo and
LOGO! 12/24RCE can be used as fast counters.
2) Analog inputs
The LOGO! versions LOGO! 24, LOGO! 24o, LOGO! 24C, LOGO! 24Co, LOGO! 12/24RC,
LOGO! 12/24RCo and LOGO! 12/24RCE are equipped with the inputs I1, I2, I7 and I8, which
can also be programmed for use as AI3, AI4, AI1 and AI2 inputs. As described in topic
"Setting the number of AIs in the LOGO! Basic (Page 299)", you can configure these
modules to use either two analog inputs (AI1 and AI2), or all four. Signals at the I1, I2, I7 and
I8 inputs are interpreted as digital values, and those at the AI3, AI4, AI1 and AI2 inputs are
interpreted as analog values. Note that AI3 corresponds to I1 and AI4 corresponds to I2.
This numbering preserves the previous correspondence of AI1 to I7 and AI2 to I8 that was
available with the 0BA5 series. The inputs of a connected analog module are numbered
according to the already existing analog inputs. See topic "Maximum setup with expansion
and communication modules (Page 34)" for example setups. In programming mode, when
you select the input signal of a special function that takes an analog input, LOGO! offers the
analog inputs AI1 to AI8, analog flags AM1 to AM6 (0BA6) or AM1 to AM16 (0BA7), analog
outputs AQ1 and AQ2, and the block numbers of functions with analog outputs.
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! Base Module and with
those of the expansion modules, in their order of installation. See the following figure.
There are also 16 blank outputs available in LOGO! 0BA6 or 64 blank outputs available in
LOGO! 0BA7. These are identified with an x and cannot 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" (Page 231) , if only the message text is of significance to a circuit
program.

Flag blocks
Flag blocks are identified by the letters M or AM . These are virtual outputs, which output the
value of their inputs. LOGO! 0BA6 provides 27 digital flags M1 to M27 and 6 analog flags
AM1 to AM6. LOGO! 0BA7 provides 27 digital flags M1 to M27 and 16 analog flags AM1 to
AM16.
Startup flag
Flag M8 is set in the first cycle of the circuit program and can thus be used in your circuit
program as a 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.
Backlight flags M25 and M26
The M25 flag controls the backlight of the LOGO! onboard display. The M26 flag controls the
backlight of the LOGO! TD.
Note: The backlight lifetime of the LOGO! TD is 20,000 hours.

LOGO! functions
4.1 Constants and connectors - Co
Message text character set flag M27
The M27 flag selects between the two character sets that LOGO! uses to display message
texts. State 0 corresponds to Character Set 1, and state 1 corresponds to Character Set 2. If
M27=0 (low), only message texts configured for Character Set 1 will display; If M27=1 (high),
only message texts configured for Character Set 2 will display. If you do not include M27 in
the circuit program, message texts display in the character set that you selected from either
the Msg Config menu or from LOGO!Soft Comfort.
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 (if 0BA6) or S1.1 to S4.8 (if 0BA7), 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" (Page 245) special function.
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 way as other inputs. You
can set the cursor keys in the corresponding display while the system is in RUN (Page 97) ,
and in an active message text (ESC + Key). Cursor keys can save switches and inputs, and
allow operator control of the circuit program. Cursor key inputs from the LOGO! TD are
identical to cursor key inputs from the LOGO! Base Module.
LOGO! TD function keys
The LOGO! TD has four function keys that you can use in your circuit program. You program
these keys in the same way as other inputs. Like the cursor keys, you can press these keys
when LOGO! is in RUN mode to affect the behavior of the circuit program, and to save
switches and inputs. They are identified as F1, F2, F3, and F4.
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.

Basic functions list - GF
Basic functions represent simple logical elements of Boolean algebra.
You can invert the inputs of individual basic functions, that is, 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". See the programming example at Circuit program input (Page 86).
The GF list contains the basic function blocks you can use for your circuit program. The

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. Special 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 (Page 156).
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, + or -.
● En (Enable):
This input enables a block function. When this input is "0", other signals to 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.
The following connector is available only in the device series 0BA7:
● Lap (for the stopwatch function)
A signal at this input pauses the stopwatch.
Note
Unused logical inputs of special functions default to logical "0".

LOGO! functions
4.3 Special Functions
Connector X at SF inputs
SF inputs connected to connector x are set low. That is, the inputs carry a 'lo' signal.
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 specify whether a message is to be
acknowledged in RUN.
4.3.2
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:
Timebase
__:__
s (seconds)
seconds : 1/100 seconds
m (minutes)
minutes : seconds
h (hours)
hours : minutes

Exception:
The LOGO! 0BA7-specific stopwatch function provides an additional timebase - 10 ms. For a
detailed description, see the topic Stopwatch (0BA7 only) (Page 198).

LOGO! functions
4.3 Special Functions
Accuracy of T
Because of slight tolerances in the characteristics of electronic components, the set time T
can deviate. You can find a detailed description of such deviations in the "On-delay" topic
(Page 160).
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 ±2 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 of a LOGO! 0BA6 is 80 hours and the typical
backup time of a LOGO! 0BA7 is 20 days.
If there is a power outage of a LOGO! for more than 80 hours (if 0BA6) or 20 days (if 0BA7),
the internal clock responds, dependent on the equipment series, as shown below:
● Equipment series 0BA0:
On restarting, the clock is set to "Sunday 00:00 1 January". The time starts to run. Due to
this, the system processes the time switches, which trigger actions if necessary.
● Equipment series 0BA1 to 0BA6:
On restarting, the clock is set to "Sunday 00:00 1 January". The time is stopped and
flashes. LOGO! is back in the status that it was in before the power outage. In RUN
mode, the system processes the counters that were parameterized with the time above.
The clock is, however, still stopped.
● Equipment series 0BA6:
If you are using the optional LOGO! Battery card, or combined LOGO! Memory/Battery
card, LOGO! can retain the clock time for up to two years. These cards are available for
equipment series 0BA6.
● Equipment series 0BA7
On restarting, the clock is set to "Sa 00 00 2011-01-01". The time is stopped and flashes.
LOGO! is back in the status that it was in before the power outage. In RUN mode, the
system processes the counters that were parameterized with the time above. The clock
is, however, still stopped.

4.3 Special Functions
4.3.4
Retentivity
The switching states, counter and time values of many SFs (see the "Special functions list SF (Page 156)" topic) can be set retentive. This means that current data values 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 is retained.
/: Current data is not retained (default). See the section in topic "Second circuit program
(Page 100)" on enabling and disabling retentivity.
The hours counter, weekly timer, yearly timer and PI controller are always retentive.
4.3.5
Parameter protection
In the parameter protection settings, you can determine whether or not the parameters can
be displayed and edited in LOGO! parameter assignment mode. 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 programming mode. See the parameter protection mode example in the
Second circuit program (Page 100).
Note
Parameter protection covers only the "Set Param" window. If you embed variables of
protected special functions in a message text, the variables are still editable from the
message text. To protect these variables, you must also activate the protection of the
message text.

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 a range of values from 0 to
1000. An input voltage exceeding 10 V is shown as internal value 1000.
Because you cannot 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! onboard
display, which is proportional to the actual process variable.

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 +70 °C, 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

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, that is, the circuit program converts a logical "1"
at the input into a logical "0"; a logical "0" it converts into a logical "1". See the programming
example in topic "Circuit program input (Page 86)".
The table also specifies whether the relevant function can be set retentive (Rem). The

Functional description
The time Ta is triggered with a 0 to 1 transition at input Trg (Ta is the current LOGO! time).
If the status of input Trg is 1 at least for the duration of the configured time T, the output is
set to 1 on expiration of this time (the output follows the input with on-delay).
The time is reset when the status at input Trg returns to 0 before the time T has expired.
The output is reset to 0 when the signal at input Trg is 0.
If retentivity is not set, output Q and the expired time are reset after a power failure.

least for the duration of this time.
The time is reset if input En is reset before the on-delay time has expired.
A 1 to 0 transition at input EN triggers a random off-delay time between 0 s and TL.
The output is reset after the off-delay time has expired, provided input En remains lo at least
for the duration of this time.
The time is reset if the signal at input En changes to 1 again before the off-delay time has
expired.
The time expired is reset after a power failure.

A 0 to 1 transition at input Trg sets output Q.
If output Q = 0, and input Trg is set hi at least for the duration of TL, the permanent lighting
function is enabled and output Q is set accordingly.
The off-delay T is triggered when input Trg returns to 0 before TL has expired.
Output Q is reset when Ta = T.
You can output an off-warning signal prior to the expiration of the off-delay time (T - T!) that
resets Q for the duration of the prewarning time period T!L. A subsequent signal at Trg

Functional description
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 you configured an off-time, or at the
end of the cycle if you specified a pulse output. You will cause a conflict if the on- and offtimes 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.
The switching state of the weekly timer is determined by the status of all three cams.

Functional description
The yearly timer sets and resets the output at specific on and off dates. Sets and resets are
executed at 00:00. If your application requires a different time, use a weekly timer together
with a yearly timer in your circuit program.
The on time specifies when the timer is activated. The off time specifies when the output is
reset again. For the on and off times, note the order of the fields: The first field defines the
year, the second the month and the third the day.
If you set the Monthly mode on, the timer output switches on each month at the specified day
of the on time and remains on until the specified day of the off time. The on time specifies
the initial year in which the timer is activated. The off time defines the last year in which the
timer turns off. The maximum year is 2099.
If you set the Yearly mode on, the timer output switches on each year at the specified month
and day of the on time and remains on until the specified month and day of the off time. The
on time specifies the initial year in which the timer is activated. The off time defines the last
year in which the timer turns off. The maximum year is 2099.
If you set Pulse output, the timer output switches on at the specified on time for one cycle
and then the timer output is reset. You can choose to pulse a timer on a monthly or yearly
basis, or just a single time.
If you set none of the Monthly, Yearly, or Pulse modes on, you can define a specific time
period with the on time and off time. It can span any time period that you choose.
For a process action that is to be switched on and off at multiple but irregular times during
the year, you can define multiple yearly timers with the outputs connected by an OR function
block.

Functional description
The internal counter increments (Dir = 0) or decrements (Dir = 1) by one count with every
positive edge at input Cnt.
You can use input R to reset the internal count value to the start value. As long as R = 1, the
output is also 0 and the pulses at input Cnt are not counted.
If retentivity is not set, output Q and the expired time are reset after a power failure.
Q is set or reset depending on the current value at Cnt and the set thresholds. See the
calculation rule below.
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.
Note
The system scans the counter limit value cyclically.
Thus, if the pulse frequency at the fast digital inputs I3, I4, I5 or 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).

Functional description
The hours counter monitors input En. When En = 1, LOGO! computes the time expired and
the time-to-go MN. LOGO! shows these times in parameter assignment mode. Output Q is
set when the time-to-go MN = 0.
A signal at reset input R resets output Q and sets the preset value of MI at the counter for
the duration of MN. The hours counter OT is not affected.
With a signal at the reset input Ral, you reset output Q and set the preset value of MI at the
counter for the duration of MN. The hours counter OT is reset to zero.
Depending on your configuration of parameter Q, the output is either reset with a signal at
input R or Ral ("Q→0:R"), or when a reset signal is set hi, or the En signal is set lo
("Q→0:R+En").
Viewing the MI, MN and OT values
● LOGO! Basic: You can open the parameter assignment mode when the system is in RUN
to view the actual values of MI, MN and OT.
● LOGO! Pure: In LOGO!Soft Comfort, you can use the Online Test to read these values.
For further information, see chapter "LOGO! software (Page 313)".
● In LOGO!Soft Comfort you can get the hours counter via the "Tools -> Transfer: Hours
counter" menu command.

Limit value of OT
The value of the operating hours in OT is retained when you reset the hours counter with a
signal at input R. The hours counter OT will be reset to zero with a transition from 0 to 1 at
Ral. The hours counter OT continues the count as long as En = 1, irrespective of the status
at the reset input R. The counter limit of OT is 99999 h. The hours counter stops when it
reaches this value.
In programming mode, you can set the initial value of OT. MN is calculated according to the
following formula when reset input R is never enabled: MN = MI - (OT % MI). The % operator
provides an integer division remainder.
Example:
MI = 30h, OT = 100h
MN = 30 - (100 % 30)
MN = 30 -10
MN = 20h

In a heating control system, the supply Tv and return line temperatures Tr are to be
compared, for example with a sensor at AI2.
A control signal is to be triggered (for example "heater On") when the difference between the
supply and return line temperatures is greater than 15 °C. The control signal is reset when
the difference is less than 5 °C.
The process variable of the temperature is to be shown in parameter assignment mode.
The thermocouples available have the following technical data: -30 to +70 °C, 0 to 10 VDC.

$[ $\ 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.
Using this method, you will obtain a virtual hysteresis and reduce the input response to short
signals.

Functional description
A 0 to 1 transition at input En saves the value of the signal at the analog input Ax. This saved
process variable is referred to as "Aen".
Both the analog actual values Ax and Aen are multiplied by the value at parameter A (gain),
and parameter B (offset) is then added to the product:
(Ax • gain) + offset = Actual value Aen, when input En changes from 0 to 1, or
(Ax • gain) + offset = Actual value Ax.
Output Q is set when the signal at input En = 1 and if the actual value at input Ax is out of
range of Aen - Δ 2 to Aen + Δ 1 .
Output Q is reset, when the actual value at input Ax lies within the range of Aen - Δ 2 to Aen+
Δ 1, or when the signal at input En changes to lo.

Gain and offset parameters
Please note the information on gain and offset parameters in topic Calculating the gain and

Parameter p (number of decimals)
Applies only to the AQ value in a message text.
Functional description
The function fetches the analog signal of input Ax.
This value is multiplied by the value of the A (gain) parameter, and parameter B (offset) is
then added to the product: (Ax • gain) + offset = actual value Ax.
The actual value Ax is output at AQ.
Analog output
If you interconnect this special function with a real analog output, note that the analog output
can only process values between 0 and 1000. To do this, you may need to connect an
additional amplifier between the analog output of the special function and the real analog
output. Using this amplifier, you standardize the output range of the special function to a
value range of 0 to 1000.
Scaling an analog input value
You can influence the analog input value of a potentiometer by interconnecting an analog
input with an analog amplifier and an analog flag.
● Scale the analog value at the analog amplifier for further use.
● Connect, for example, the time base for parameter T of a time function (e.g. On-/Off-delay
(Page 166)) or the on and/or off limit specification of an up/down counter (Page 201) to
the scaled analog value.

Message texts
Short description
With the message text function block, you can configure a message that includes text and
other parameters for LOGO! to display in RUN mode.
You can configure simple message texts from the LOGO! onboard display. LOGO!Soft
Comfort provides an extended set of features for message texts: bar graph representation of
data, names for digital I/O states and more. Refer to the LOGO!Soft Comfort documentation
for information on these features.
Global Message Text Settings
You configure global parameters that apply to all message texts from the Msg Config
selections on the Programming menu:
● Analog Time: refresh rate in milliseconds that specifies how frequently analog inputs in
message texts are updated
● Tick time: frequency at which message texts scroll on and off the display
There are two ways that a message text can tick on and off the screen: line by line, or
character by character, which are described in more detail below. A line of a text
message, or each character of a text message in turn will tick on and off the
LOGO! onboard display based on the tick time. For a message that ticks line by line, the
actual tick time is ten times the configured tick time. For messages that tick character by
character, the actual tick time is the configured tick time.
● CharSets: The primary and secondary character sets from which you can configure
message texts. CharSet1 and CharSet2 can be any of the supported character sets for
LOGO!:

● Current Character Set: which character set is selected for the display of message texts
Note
Message texts supported by LOGO! 0BA5 will display on the LOGO! TD only when the
following conditions are met:
- CharSet1 is selected and set to ISO8859-1
- Current Character Set "CurrCharSet" is set to CharSet1
Of the fifty possible message texts that you can configure, you can select any number of
them to be from the first language and any number from the second language. For example,
you could configure fifty message text function blocks that have a single message text for
Character Set 1. Alternatively, you could configure twenty-five message text function blocks,
each of which has two message texts: one for Character Set 1 and one for Character Set 2.
Any combination is valid such that the total does not exceed fifty.
Within a single message text, the text must be from one character set. You can edit
message texts in any of the supported character sets from LOGO!Soft Comfort. From the
LOGO! Basic, you can only edit text using characters from the ISO8859-1 character set.
The language and therefore character set of a message text is independent of the language
setting for menus on the LOGO! onboard display. They can be different.
Chinese Character Set
The LOGO! Basic and LOGO! TD support the Chinese character set (GB-2312) for the
People's Republic of China. The devices use Microsoft Windows encoding for this character
set. The Windows encoding allows the devices to display the same characters as shown in
the LOGO!Soft Comfort message text editor when you are using a Chinese emulator or a
Chinese version of Microsoft Windows.
The Chinese character set requires a Chinese version of Windows or a Chinese emulator to
properly display Chinese characters in the LOGO!Soft Comfort message text editor. You
must start the Chinese emulator before you open the the message text function block in
LOGO!Soft Comfort.

Functional description
When LOGO! is in RUN mode, LOGO! displays the message text that you have configured
along with its parameter values upon a 0 to 1 transition of the signal at input En.
Based on your setting for the message destination, the message text displays on the
LOGO! onboard display, the LOGO! TD, or both.
If you use flag M27 in your circuit program, then if M27=0 (low) then LOGO! displays the
message text only if it is from the primary character set (Character Set 1). If M27=1 (high),
then LOGO! displays the message text only if is from the secondary character set (Character
Set 2). (See the M27 flag description in topic Constants and connectors - Co (Page 138)).
If you have configured message ticking, the message will tick on and off the display
according to your specifications, either a character at a time, or a line at a time.
If acknowledgment is disabled (Ack = Off), the message text is hidden when the status of the
signal at input En changes from 1 to 0.
If acknowledgment is enabled (Ack = On) and the status of the signal at input En changes
from 1 to 0, the message text is output until it is acknowledged with OK. When En = 1, you
cannot acknowledge the message text.
When multiple message text functions are triggered with En=1, LOGO! displays the message
text with the highest priority (0 = lowest, 127 = highest). This also means that LOGO!
displays a newly activated message text only if its priority is higher than that of previously
activated message texts.
After a message text is disabled or acknowledged, the function automatically shows the
previously active message text that takes the highest priority.
You can press the
and
keys to step through multiple active message texts.

Message Ticking
You can configure message text lines to tick or not tick. Two types of message ticking exist:
● Character by character
● Line by line
Messages that tick character by character scroll off the characters of the message line one
character at a time to the left with the additional characters scrolling in one at a time from the
right. The time interval for the tick is specified by the TickTime message text setting.
Messages that tick line by line by line scroll one half of the message off the display to the left
with the second half of the message scrolling in from the right. The time interval for the tick is
ten times the TickTime parameter. The two halves of the message simply alternate on the
LOGO! onboard display or LOGO! TD.

4.4 Special functions list - SF
Functional description
The function reads the value at input In with a positive edge (0 to 1 transition) at input Trg
(Trigger).
If your LOGO! is a LOGO! 0BA6, 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.
If your LOGO! is a LOGO! 0BA7, this value is applied to shift register bit Sx.1 or Sx.8
depending on the shifting direction, where "x" refers to the index number of the shift register
and the number after the decimal point refers to the bit number:
● Shift up: The value at input In is set at Sx.1; the previous value at Sx.1 is shifted to Sx.2;
the previous value at Sx.2 is shifted to Sx.3 etc.
● Shift down: The value at input In is set at Sx.8; the previous value at Sx.8 is shifted to
Sx.7; the previous value at Sx.7 is shifted to Sx.6 etc.
Output Q returns the value of the configured shift register bit.
If retentivity is disabled, the shift function restarts at Sx.1 or Sx.8 after a power failure. When
enabled, retentivity always applies to all shift register bits.
Note
There is only one shift register function block available for use in the circuit program in
LOGO! 0BA6.
There are a maximum of four shift register function blocks available for use in the circuit
program in LOGO! 0BA7.

Functional description
If input En is set, then the function issues one of four possible analog values V1 to V4 at the
output AQ, depending on the value of S1 and S2.
If the input En is not set, then the function issues the analog value 0 at output AQ.
Analog output
If you interconnect this special function with a real analog output, note that the analog output
can only process values between 0 and 1000. To do this, you may need to connect an
additional amplifier between the analog output of the special function and the real analog
output. Using this amplifier, you standardize the output range of the special function to a
value range of 0 to 1000.

Functional description
If the input En is set, then the function sets the current level to StSp + Offset "B" for 100 ms.
Then, depending on the connection of Sel, the function runs from the level StSp + Offset "B"
to either level 1 or level 2 at the acceleration set in Rate.
If the input St is set, the function runs to a level of StSp + Offset "B" at the acceleration set in
Rate. Then the function holds the level at StSp + Offset "B" for 100 ms. After 100 ms, the
level is set to Offset "B". The scaled value (output AQ) is 0.
If the input St is set, the function can only be restarted after the inputs St and En have been
reset.
If input Sel has been changed, depending on the connection of Sel, the function runs from
the current target level to the new target level at the rate that is specified.
If the input En is reset, the function immediately sets the current level to Offset "B".
The current level is updated every 100 ms. Note the relationship between output AQ and the
current level:
Output AQ = (current level - Offset "B" ) / Gain "A"

1. A disturbance causes the PV to drop, as Dir is positioned upwards, AQ increases until PV
corresponds again to SP.
2. A disturbance causes the PV to drop, as Dir is positioned downwards, AQ decreases until
PV corresponds again to SP.
It is not possible to change the direction (Dir) at runtime of the function. The change is
shown here for illustrative purposes only.
3. As AQ is set to 0 by means of the input R, PV changes. This is based on the fact that PV
increases, which on account of Dir = upwards causes AQ to drop.

Functional description
If the input A/M is set to 0, then the special function issues output AQ with the value that you
set with parameter Mq.
If the input A/M is set to 1, then automatic mode commences. As an integral sum the value
Mq is adopted, the controller function begins the calculations.
Note
For further information on the controller basics, please refer to the online help for LOGO!Soft
Comfort.
The updated value PV is used to calculate in the formulas:
Updated value PV = (PV • gain) + offset
● If the updated value PV = SP, then the special function does not change the value of AQ.
● Dir = upwards (+) (timing diagram numbers 1. and 3.)
– If the updated value PV > SP, then the special function reduces the value of AQ.
– If the updated value PV < SP, then the special function increases the value of AQ.
● Dir = downwards (-) (timing diagram number 2.)
– If the updated value PV > SP, then the special function increases the value of AQ.
– If the updated value PV < SP, then the special function reduces the value of AQ.
With a disturbance, AQ continues to increase / decrease until the updated value PV again
corresponds to SP. The speed with which AQ changes depends on the parameters KC and
TI.
If the input PV exceeds the parameter Max, then the updated value PV is set to the value of
Max. If the PV falls short of the parameter Min, then the updated value PV is set to the value
of Min.
If the input R is set to 1, then the AQ output is reset. As long as R is set, the input A/M is
disabled.
Sampling time
The sampling time is fixed at 500 ms.
Parameter sets

Functional Description
The mathematic instruction function combines the four operands and three operators to form
an equation. The operator can be any one of the four standard operators: +, -, *, or /. For
each operator, you must set a unique priority of High (H), Medium (M), or Low (L). The high
operation will be performed first, followed by the medium operation, and then by the low
operation. You must have exactly one operation of each priority. The operand values can
reference another previously-defined function to provide the value. The mathematic
instruction function rounds the result to the nearest integer value.
The number of operand values is fixed at four and the number of operators is fixed at 3. If
you need to use fewer operands, use constructions such as + 0 or * 1 to fill the remaining
parameters.
You can also configure the behavior of the function when the Enable parameter En=0. The
function block can either retain its last value, or be set to 0. If the parameter Qen → 0 = 0,
then the function sets AQ to 0 when En=0. If the parameter Qen → 0 = 1, then the function
leaves AQ at its last value when En=0.
Possible errors: Zero division and overflow
If the mathematic instruction function block execution results in zero division or overflow, it
sets internal bits that indicate the type of error that occurred. You can program a mathematic
instruction error detection function block in your circuit program to detect these errors, and to
control the program behavior as needed. You program one mathematic instruction error
detection function block to reference one specific mathematic instruction function block.

Parameter MathBN
The value for the MathBN parameter references the block number of an alreadyprogrammed mathematic instruction function block.
Functional description
The mathematic instruction error detection block sets the output when the referenced
mathematic instruction function block has an error. You can program the function to set the
output on a zero division error, an overflow error, or when either type of error occurs.
If AutoRst is set, the output is reset prior to the next execution of the function block. If
AutoRst is not set, then whenever the output is set it remains set until the mathematic
instruction error detection block is reset with the R parameter. This way, even if the error
subsequently clears, the circuit program still has knowledge that an error did occur at some
point.
In any scan cycle, if the referenced mathematic instruction function block executes before
the mathematic instruction error detection function block, the error is detected in the same
scan cycle. if the referenced mathematic instruction function block executes after the
mathematic instruction error detection function block, the error is detected in the next scan
cycle
Mathematic instruction error detection logic table
In the table below, Err represents the parameter of the mathematic instruction error detection
instruction that selects which type of error to detect. ZD represents the zero division bit set
by the mathematic instruction at the end of its execution: 1 if the error occurred, 0 if not. OF
represents the overflow bit set by the mathematic instruction: 1 if the error occurred, 0 if not.
The ZD/OF Err parameter represents the logical OR of the zero division bit and overflow bit
of the referenced mathematic instruction. Q represents the output of the mathematic
instruction error detection function. An "x" indicates that the bit can be either 0 or 1 with no
influence on the output.

Data Log (0BA7 only)
You can configure a maximum of one Data Log for your circuit program using LOGO!Soft
Comfort. The Data Log is used to record process measurement variables of the selected
function blocks. You can add the Data Log instruction to your circuit program as you do with
a function block.
If you configured the Data Log for your circuit program, after transferring the program from
LOGO!Soft Comfort to LOGO!, you can edit the elements connected to the Data Log block.
For a detailed description of configuration of the Data Log function in LOGO!Soft Comfort,
refer to the online help for LOGO!Soft Comfort V7.0. From LOGO! 0BA7, you can only
configure elements connected to the Data Log block.

Note
LOGO! 0BA7 provides a 1024-byte buffer for data logging. If the data in this buffer
reaches 512 bytes, LOGO! automatically writes data to the SD card inserted in the SD
card slot. If the speed of data generation in LOGO! 0BA7 is faster than that of data write
to the SD card, data loss may occur. To avoid the occurrence of data loss, apply an
enable signal to the data log function block at a minimum time interval of 500 ms.
A data log file on the SD card can store a maximum of 2,000 records.
Only the most recent data log file on the SD card can be uploaded from LOGO! to
LOGO!Soft Comfort.
Under the following three circumstances, LOGO! creates a new data log file:
• When LOGO! has downloaded a circuit program configured with the data log function
from LOGO!Soft Comfort
• When the data log file in LOGO! is not properly closed at the time LOGO! in RUN
mode is powered off
• When your edits to the circuit program in LOGO! influence the data log configuration
made in LOGO!Soft Comfort

Parameter assignment refers to the configuration of the block parameters. You can set delay
times for time functions, the switching times of timers, counter threshold values, the
monitoring interval of an hours counter, the on and off thresholds of the trigger, and more.
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
Parameter assignment mode allows the editing of parameters without having to modify the
circuit program. This feature is available so that you can edit parameters without having to
change to programming mode. The advantage: The circuit program remains protected, but
can be adapted by the user to meet specific requirements.
Note
In parameter assignment mode, LOGO! continues execution of the circuit program.

LOGO! 0BA6 provides the following cards for program storage and real-time clock backup:
● LOGO! Memory Card
● LOGO! Battery Card
● LOGO! Memory/Battery Card
Each of the three cards is color-coded to make them easily distinguishable from one another.
They also vary in size. The LOGO! Memory Card (purple) provides storage for the circuit
program. The LOGO! Battery Card (green) provides battery backup of the real-time clock for
up to two years. The LOGO! Memory/Battery card (brown) provides both circuit program
storage and battery backup of the real-time clock.
LOGO! 0BA7 does not support the above-mentioned three cards. LOGO! 0BA7 only
supports standard SD cards for program storage.
WARNING
Risk of death, personal injury or property damage can occur if you use the battery card or
combined memory/battery card in a hazardous location.
Do not insert/remove the memory card, battery card, or combined memory/battery card in
hazardous locations.
The LOGO! 0BA6 Memory Card and the LOGO! 0BA6 Memory/Battery Card provide 32
Kbytes memory space: four times the memory space of the LOGO! 0BA5 Memory Card.
LOGO! allows you to store only one circuit program in its memory. If you want to modify the
circuit program or create an additional one without deleting the first, you must archive it
somewhere.
You can copy the LOGO! circuit program to a LOGO! Memory Card, a LOGO!
Memory/Battery card, or a standard SD card (0BA7 only). You can then insert this card in
another LOGO! of the same device series in order to copy the circuit program. This enables
you to manage your programs in the following ways:
● Archive circuit programs
● Reproduce 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 LOGO! Memory Card, LOGO! Battery Card and LOGO!
Memory/Battery Card are supplied separately.

Note
You do not need a memory card or combined memory/battery card to backup the circuit
program in your LOGO!
The LOGO! circuit program is automatically stored in nonvolatile memory when you exit the
programming mode.
You can backup the LOGO! circuit program on a memory card, a combined memory/battery
card, or a standard SD card. The order numbers are found in the Appendix section entitled
"Order numbers (Page 363)".
Compatability (Old memory cards in newer LOGO! modules)
... to earlier versions (0BA4 and 0BA5 devices):
Data written to the memory card in an 0BA5 version can be read in all 0BA6 versions. 0BA4
memory cards cannot be read by 0BA6 versions.
... to earlier versions (0BA0 to 0BA3 devices):
A memory card that contains data written in earlier versions (0BA0...0BA3 devices) cannot
be used in LOGO! devices of the 0BA4 and later generations. When the LOGO! system
detects such an 'old' memory card, the message "Unknown Card / Press ESC" is output to
the display.
Vice versa, a 0BA4 or later memory card cannot be used in LOGO! devices of the
0BA0...0BA3 family.
Compatibility (New memory, battery, or combined memory/battery cards in older LOGO! modules)
The LOGO! 0BA6 memory card can be used in 0BA4 or 0BA5 devices to store a circuit
program but cannot be used in 0BA0 ... 0BA3 devices.
A LOGO! 0BA6 Memory Card or LOGO! 0BA6 Memory/Battery Card that already has a
LOGO! 0BA6 circuit program stored on it cannot be used in any device other than a LOGO!
0BA6 device.
A LOGO! 0BA6 Battery Card or LOGO! 0BA6 Memory/Battery Card can only be used in
0BA6 devices.
A standard SD card can only be used in device series 0BA7.

Security function (CopyProtect)
The security function provides copy protection for circuit programs on memory cards,
combined memory/battery cards or SD cards.
Unprotected cards
You can edit circuit programs without restrictions and exchange data between the card and
the device.
Protected cards
A circuit program is protected when it is transferred from a protected program card to
LOGO!.
To execute this circuit program in LOGO!, the protected card must remain inserted during
RUN; that is, the circuit program stored on the card cannot be copied to other LOGO!
devices.
In addition, a protected circuit program is write-protected.
A circuit program with password protection is no longer protected after the correct password
has been entered; that is, you can then edit the program and remove the card.
Note
When you create the circuit program for a card, you need to assign a password (Page 91) to

Inserting and removing the card from LOGO!
When you remove a LOGO! memory card, a combined memory/battery card, or an SD card
that contains a circuit program with copy protection attributes, note the following: The circuit
program stored on the card can only be executed if the card remains inserted during system
runtime.
After you have removed the card, LOGO! outputs the message 'No Program'. A removal of
the card during RUN will lead to impermissible operating states.
Always heed the following warning:
WARNING
Do not touch the open slot of the memory card or SD card with your fingers or with a
metallic or conductive object. Death or personal injury may result.
The memory card/SD card socket might be under voltage if the polarity is accidentally
reversed at L1 and N.
The memory card, battery card, or combined memory/battery card must only be removed
by qualified personnel using the directions below.
Removing the memory card, battery card or combined memory/battery card
To remove the memory card, carefully insert a screwdriver with a 3-mm blade into the
groove on the upper end of the card, and lever the module partially out of the slot. You can
now remove the memory card.

8.3 Copying data from LOGO! to the card
Copying data from LOGO! 0BA7 to the SD card automatically
LOGO!Soft Comfort V7.0 provides an option for automatically copying the circuit program to
the SD card when transferring the circuit program to LOGO! 0BA7. This option is available in
the dialog for PC->LOGO! transfer. If you select this option, the circuit program is transferred
to LOGO! 0BA7 and then automatically copied from LOGO! 0BA7 to the SD card.
Note
To successfully copy the circuit program from LOGO! 0BA7 to the SD card, make sure that
the free memory space available on the SD card is at least 65 Kbytes.
Generating the data log on the SD card
If your circuit program in LOGO! 0BA7 includes a Data Log function block configured from
LOGO!Soft Comfort, the data log can be saved in your LOGO! or on the SD card. If there is
an SD card inserted into the slot of your LOGO! 0BA7, when LOGO! changes from STOP to
RUN, it attempts to copy the data log to the SD card; otherwise, the data log is saved in
LOGO!. At every STOP to RUN transition, LOGO! determines the destination of the data log
storage.
If the data log is copied to the SD card, it is saved by default as .CSV file format, which you
can then open from a PC. Each line in the .CSV file includes a time stamp, the function block
number and the actual values recorded.
Note
When LOGO! with an inserted SD card is in STOP mode, you can upload the most recent
data log file on the SD card to LOGO!Soft Comfort using a transfer menu command in
LOGO!Soft Comfort. For more information about the data log uploading command, refer to
the online help for LOGO!Soft Comfort.

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 but 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.

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.

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.

Determining the cycle time
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.

Because some specific applications do not require operator control and monitoring units
such as buttons or a display, we provide the LOGO! 12/24RCo, LOGO! 24o, LOGO! 24Co,
LOGO! 24RCo and LOGO! 230RCo versions without display.

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 Comfort
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 LOGO!.
● You download the circuit program from a LOGO! memory card or combined
memory/battery card (Page 303) to your LOGO! without display.

LOGO! without display ("LOGO! Pure")
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 cannot 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 LOGO! or on the inserted memory card or combined
memory/battery 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 memory card or combined memory/battery card is
automatically copied to 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 LOGO! (Page 315), you can download the circuit
program to LOGO! and start it by means of LOGO!Soft Comfort PC software.
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 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 memory card or combined memory/battery
card, you cannot read the current data unless you enter the correct password (Page 305) for
the circuit program. The circuit program is otherwise deleted from LOGO! memory when you
remove the memory card or combined memory/battery card to connect the PC cable.
Deleting the circuit program
Use LOGO!Soft Comfort to delete the circuit program and password if a password exists.
