Description

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.
 

Functionality

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.

Highlights of the new LOGO! 8

  • 8 basic units for all voltages, four of them with a new display
  • All units come with an Ethernet interface, footprint like LOGO! 6 (4TE); and connections are compatible with previous versions
  • Several versions 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
  • Connectivity for remote LOGO! 8 text display via Ethernet for all LOGO! 8 basic modules
  • Extented temperature range -20 to 55°C, without condensation
