LOGO! Modular Pure-Variants

Logic module LOGO!


With LOGO!, Siemens offers you the ideal controller for simple automation tasks in industry and building services. The modular design of LOGO! makes it consistently flexible.
A wide range of modules allows you to create a configuration to meet your needs.
A wide range of modules allows individual expansion of LOGO!

LOGO! pure versions are available for generation LOGO! 6 and LOGO! 8.
They are cost optimized devices mainly for serial machinery where the end user doesn’t need to have access to any parameters or status information of the I/O signals.
This modules have the same features like the modules with display.
Please note: All features that need the display or function keys are not available.

You may connect an external text display to operate the units. With LOGO! 8, you can use the integrated web server without any display attached. The web server is based on the message text function block.
LOGO! pure modules are programmed mainly via LOGO! SoftComfort and set to “RUN” mode.
If you insert a memory medium with a valid, executable program, the program will be copied to the internal LOGO! memory after “power ON” and the LOGO! will be automatically set to “RUN” mode.

LOGO!8 The new generation

Programming is done either with LOGO! SoftComfort or via a standard Micro SD card. The integrated WEB server can be used without any Display connected.

The external display LOGO! TDE offers 6 lines, 20 characters per line and 3 background colors and is connected via Ethernet. 
Four function keys allow a very cost efficient monitoring and operation.
For higher requirements a SIMATIC HMI panel can be used.

LOGO! – the proven basic (0BA6)

Programming is done either with LOGO! SoftComfort or via a LOGO! memory card.

Flexibility is always assured due to the diverse expansion options including KNX and AS-I connections.
The LOGO! TD text display (4 lines each max 32 characters and 4 additional function keys) allows a very cost efficient monitoring and operation. It can be up to 10 m away from the LOGO!.

Design and functions

LOGO! 8 The new generation of logic modules

  • 4 basic units for all voltages

  • All units come with an Ethernet interface, narrow like LOGO! 6 (4TE);
    and connections are compatible with previous versions

  • Several version for different supply power DC 12V/24V RCE, AC/DC 24V RCE, DC 24V CE,
    AC/DC 115/240V RCE

  • 400 blocks program memory

  • Integrated web server in all basic units

  • Display with a new look and feel (6-lines with 16 characters each, 3 background colors)

  • Connectivity for remote LOGO! 8 text display via Ethernet for all LOGO! 8 basic modules

  • Message texts, actual values, set points can be shown on the external display, parameters
    can be changed. You can also watch the status of digital and analog Inputs and outputs.

  • Seven digital modules and three analog modules for additional I/Os

  • Digital outputs increased to 20 and analog outputs to 8

  • A maximum of 9 LOGO!s can be networked

  • Communication to SIMATIC S7 CPUs and HMI possible

  • Data logging

  • Standard SD cards as the storage medium

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

  • Reference of parameters now as graphic view

  • Program and connection compatible with earlier LOGO! versions

  • Please note: LOGO! 8 basic modules only accept the new expansion modules and LOGO! TDE

LOGO! Basic (0BA6)

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