New features of the LOGO! 0BA6 device series
●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.
●Additional optional analog inputs and fast digital inputs are available on some of the
LOGO! 0BA6 Base Modules.
●LOGO! 0BA6 configuration menus can be displayed in one of ten supported languages.
You have a configuration choice to specify the language for LOGO! menus.
●New instruction blocks are available: Pulse Width Modulator (PWM), Analog Math, and
Analog Math Error Detection.
●Message texts can tick on and off the display; can include bar graphs, can switch
between two character sets, and can be displayed on either the LOGO! onboard display,
the LOGO! TD, or both. Full editing capabilities are available from LOGO!Soft Comfort;
editing from the LOGO! Basic is limited to simple text. See topic "Compatibility (Page 31)"
for further details.
●A modem interface between a PC and LOGO! 0BA6 Base Module is supported, and is
configurable only from LOGO!Soft Comfort. LOGO! 0BA6 supports the following modems:
–INSYS Modem 336 4 1
–INSYS Modem 56K small INT 2.0
You can also use other modems with LOGO! 0BA6 provided that these modems meet the
requirements specified in the "Connecting modems (Page 51)" topic.
●USB PC cable between a PC and LOGO! Base Module is available as an option.
●Modem cable between a modem and LOGO! Base Module is available as an option.
●This series supports 0/4–20 mA for the AM2 AQ analog outputs.
●You can now have up to 200 program blocks in your circuit program.

Here's LOGO!
LOGO! is a universal logic module made by Siemens that integrates:
●Controls
●Operator and display panel with background lighting
●Power supply
●Interface for expansion modules
●Interface for a memory card, battery card, combined memory/battery card, LOGO! PC
cable or USB PC cable.
●Interface for an optional text display (TD) module
●Pre-configured standard functions, for example, on- and off-delays, pulse relay and
softkey
●Timers
●Digital and analog flags
●Inputs and outputs, according to the device type
What LOGO! can do for you
LOGO! offers solutions for domestic and installation engineering applications such as
stairway lighting, external lighting, sun blinds, shutters, shop window lighting and more;
switch cabinet engineering, as well as for mechanical and apparatus engineering such as
gate control systems, air-conditioning systems, and rainwater pumps.
LOGO! can also be implemented for special control systems in conservatories or
greenhouses, for control signal processing and, by connecting a communication module
such as an AS-i module, for distributed local controlling of machines and processes.
Special versions without operator panel and display unit are available for series production
applications in small machine, apparatus, switching cabinet and installation engineering.

12 Manual, 10/2017, A5E01248535-AA
Which devices are available?
LOGO! Base Modules are available in two voltage classes:
●Class 1 ≤ 24 V, i.e. 12 V DC, 24 V DC, 24 V AC
●Class 2 > 24 V, i.e. 115...240 V AC/DC
LOGO! Base Modules are available in two versions:
●
LOGO! Basic
(version with display): 8 inputs and 4 outputs
●
LOGO! Pure
(version without display): 8 inputs and 4 outputs
Each version is integrated into four subunits, is equipped with an expansion interface and
LOGO! TD interface and provides 39 pre-configured standard and special function blocks for
the creation of your circuit program.
Which expansion modules are available?
●LOGO! digital modules DM8... are available for operation with 12 V DC, 24 V AC/DC and
115...240 V AC/DC, and are equipped with four inputs and four outputs.
●LOGO! digital modules DM16... are available for operation with 24 V DC and 115...240 V
AC/DC, and are equipped with eight inputs and eight outputs.
●LOGO! analog modules are available for operation with 24 V DC and some with 12 V DC,
depending on the specific module. Each is equipped with two analog inputs, two PT100
inputs, two PT100/PT1000 inputs (either PT100 or PT1000 or one of each), or two analog
outputs.
The digital/analog modules are integrated in two or four subunits. Each one is equipped with
two expansion interfaces for connecting additional modules.
Which display modules are available?
●LOGO! Basic
●LOGO! TD

Manual, 10/2017, A5E01248535-AA 13
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.

14 Manual, 10/2017, A5E01248535-AA
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 29).
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 AM1 to AM6
•Shift register bits S1 to S8
•4 cursor keys
•16 blank outputs X1 to X16
