connections with other SIMATIC devices across Ethernet. Those SIMATIC devices
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
program from the card to a LOGO! 0BA7.
Note
LOGO! 0BA7 only supports SD cards with a maximum memory capacity of 8 GB and a
maximum data transfer speed of 48Mbits/s or 6MB/s (Class 6).

Preface
LOGO!
Manual, 04/2011, A5E03556174-01 5
● 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

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.

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 (if 0BA6) or six (if 0BA7) subunits, is equipped with an
expansion interface and LOGO! TD interface and provides 39 (if 0BA6) or 44 (if 0BA7) pre-
configured standard and special function blocks for the creation of your circuit program.
Note
The LOGO! 0BA7 Base Modules currently released are only the LOGO! Basic version.
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

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
LOGO! 0BA7 additionally supports display of the following network digital/analog inputs and
outputs if you have previously configured them in the circuit program in LOGO!Soft Comfort
V7.0 and downloaded the program to the 0BA7 device:
•64 network digital inputs: NI1 to NI64
•32 network analog inputs: NAI1 to NAI32
•64 network digital outputs: NQ1 to NQ64
•16 network analog outputs: NAQ1 to NAQ16
