LOGO! Modular Basic Variants

Logic module LOGO! Simply different – simply ingenious


LOGO! Modular Basic Variants

LOGO! – the proven basic (0BA6)

LOGO! impresses customers due to the wide variety of possible applications and it allows the easy implementation of comprehensive applications – last but not least due to the possibility of selecting from among 38 integrated functions and linking them to up to 200 blocks. When operating and monitoring, the 4-line backlit display with a maximum of 32 characters per line ensures a high degree of user-friendliness. The message text allows the display of text, set points and actual values, bar graphs and status parameters. Of course, parameters can be adjusted in the message text. Flexibility is always assured due to the diverse expansion options.

... and the new ones with Ethernet (0BA7)

You have grown with LOGO! and you want to always be able to solve more tasks with a greater demand on industrial communication? Then, the new LOGO! 0BA7 devices are the ideal solution for you. With the new basic devices, you can easily expand old programs by adding functions. In one application you can now use up to 400 function blocks.

Also possible: the supplementing of additional I/Os or the integration of a user-friendly operator guidance via touch panels. Previously developed LOGO! programs can be used as a basis and the easy configuration continues. Five new function blocks open additional applications.

Machine controls

  • Motor, pump and valve controls

  • Air compressors

  • Exhaust and filtering systems

  • Water-treatment plants

  • Woodworking machinery

  • Etching and purification plants

Transport facilities

  • Conveyor systems

  • Hoisting platforms

  • Elevators

  • Silo facilities

  • Livestock feed delivery

Operational monitoring systems

  • Access control

  • Vehicle control monitoring

  • Alarm systems

  • Level limit monitoring

  • Traffic light control systems

  • Baggage handling

Residential and commercial building services

  • Interior and exterior lighting control

  • Door/gate control

  • Shutter, sun blind and awning control

  • Irrigation system control

Unique applications

  • Solar-electric systems

  • Marine

  • Harsh environments

  • Display panels and traffic control signs


  • the ideal controller for simple automation tasks

  • reduces costs - replaces many conventional switching control devices,

  • reduces time requirements – simplified wiring and panel layout,

  • reduces space requirements in the switching cabinet - modules based on a 4 width industry standard dimension replace a wide variety of relays, timer switches and contactor relays

  • offers the widest range of capabilities and successful implementation of extensive applications with the option of selecting from 38/43 integrated functions and linking up to 200/400 of them in the user program

  • Operator control and monitoring are made extremely user-friendly by means of a 4 line, 32 characters per line, backlit display.

  • This allows for the display of text, action items and current values, bar graphs and I/O status. Parameter values can also be changed in the message text.

  • Additional external textdisplay extends the possibilities for operator control and monitoring

  • The LOGO! is suitable for almost any small industrial or non-manufacturing commercial application.

  • Together with the LOGO! Soft Comfort software, configuring of the logic module is simply intuitive: program generation, project simulation and documentation are accomplished using drag and drop functionality, allowing maximum ease of operation.

Design and functions

LOGO! Basic and LOGO! Pure (0BA6)

  • Different voltages, i. e. 12 V DC, 24 V AC / DC, 115 / 240 V AC / DC – Can be used for a wide range of applications

  • Automatic changeover for configured daylight saving time – Reduces maintenance overhead

  • Password protection – Protects your engineering IP

  • 38 integrated, pre-tested functions – No additional devices, such as elapsed time counter, are required

  • Linking of 200 functions is possible – Extensive applications can be implemented without restrictions

  • Eight digital inputs (incl. four AIs at 12 / 24 V DC) and four digital outputs on board

  • Display of message texts, action items and current values as well as direct modification of the values on the display (except for Pure versions)

  • Retentive data memory – Protects current values against loss in the event of a power failure

  • Flexibly expandable up to 24 DIs, 16 DOs, 8 AIs and 2 AOs– Protects original investment– Suitable for a wide variety of applications

  • Software LOGO! Soft Comfort V6 for user-friendly generation of control programs on PC; suitable for a variety of operating systems, such as Windows 95/98, NT 4.0, Me, 2000, XP, Vista, MAC OS X 10.4 with J2SE 1.5.0 and SUSE LINUX 10.0

  • Connection facility for remote text display on all 0BA6 basic devices

LOGO! Basic (0BA7)

The highlight of the 0BA7 basic devices is without a doubt the standard Ethernet interface, as a programming interface and for communicating with other LOGO! 0BA7 basic devices or SIMATIC automation components such as SIMATIC S7 CPUs, HMI Panels, and PCs.

  • A maximum of 9 LOGO!s can be networked

  • Data logging

  • Standard SD cards as the storage medium

  • Program and connection compatible with LOGO! 0BA6

  • 400 blocks program memory

  • New function blocks Astronomical clock, Average value, Analog filter, Stopwatch and Min/Max Function

  • Editing of „User defined Functions“ (macro function blocks)

  • Additional reference options and display features in the function blocks
