LOGO! basic modules without display
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!
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! basic modules without Display 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.
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.
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.
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
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
Extented temperature range -20 to 55°C, without condensation
Integrated Modbus TCP/IP communication
Date- and time synchronization via NTP
LOGO! Access Tool for writing process values directly into an Excel sheet in RUN mode of the LOGO!
