LOGO! Basic Modules

LOGO! Basic Modules

The big heart of a small controller 

LOGO! is the perfect choice for the fast, uncomplicated and space-saving solution of simple control and regulation tasks. LOGO! has long since established itself as an intelligent logic module in small automation projects.


LOGO! 8 The new generation of logic modules

LOGO! simple, simply, flexible, 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 consistently flexible. A wide range of modules allows you to create configurations to meet your needs.


Despite the ongoing and consistent development of the functionality, ease of operation for programmers and users has always been paramount. 
For this reason we introduced "ready-to-use functions" such as ON/OFF delay, weekly timer, pulse generator, astro timer, annual timer, stop watch, etc. which usually have to be programmed first in a typical PLC. More than 40 functions are available and programs can include up to 400 blocks. Customers can use LOGO! to program their own macro functions and create libraries from tested subfunctions. The option to record data opens up new areas of application.
