LOGO! Modular Basic Variants

Logic module LOGO! Simply different – simply ingenious


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

LOGO!8 The new generation

This new model accommodates virtually every application demand with simplified handling, a new display, and full communication options via Ethernet. The web server application makes everything very simple.

A New 6 line display with 16 characters per line. Means twice the number of characters per message and allows you to create clearessages. Three backlight colors are selectable.
Remote communication via  mobile network (GSM), time synchronisation and position detection (GPS) provided by a communication module CMR completes the spectrum of new opportunities for LOGO!.

LOGO! (0BA7) --- with Ethernet

Have you grown with LOGO! and do you want to always be able to solve more tasks with a greater use of industrial communication?
Then, LOGO! 0BA7 devices are a good solution for you.
With the basic devices LOGO! 7, you can easily expand old programs by adding functions. 
The supplementing of additional I/Os or the integration of user-friendly operator guidance via touch panels is also possible.
LOGO! 7 can be integrated into KNX and AS-I networks.
Five additional function blocks and 400 block program capacity open new applications for the LOGO!.
Data logging on SD cards and creating of your own macro function block libraries is possible.

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 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, status parameters. Parameters can be adjusted in the message text.
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) allow a very cost efficient monitoring and operation. It can be up to 10 m away from the LOGO!.
