Siemens Logo PLC Series ,PLC Modules 8

Siemens Logo PLC

Siemens LOGO! Logic Modules are the ideal controller for small automation tasks in home, industrial and building services. These intelligent Logic Modules provide unparalleled user friendliness and usability and handles nearly every functional requirement with high speed and precision. The modular design of the LOGO! units and extras give you flexability with your projects and allow for easy expansion. With a growing range of LOGO! Expansion modules, you can increase the amount of digital/analog inputs and outputs you have.

Siemens LOGO! Micro-PLC’s are available in a wide range of supply voltages making them ideal for every environment. The LOGO! can be purchased individually or as part of a Starter Kit, which contain all the nessicary equipment to get you up and running. The most popular being the OBA7 with its new intergrated ethernet port which can be used for many tasks including direct programming of the units.

Siemens Logo PLC Overview

What distinguishes LOGO!?

LOGO! from Siemens offers you the support you need at a price you can afford. Perform small-scale automation tasks more quickly and free up space in your switch cabinet.System Overview
With 8 basic logic functions and 30/35 special functions, the LOGO! logic module can replace a large number of conventional switching and control devices. The natural logic module choice: LOGO! now is even more versatile for analog value applications and simple control tasks.

The integrated display of LOGO! can be used to show and change process parameters, as well as for programming of LOGO!.
LOGO! 8 with the new display accommodates virtually every demand of customers with simplified handling, and full communication options via Ethernet. The web server application does not need any html knowledge.
Via Ethternet communication you can create configurations including SIMATIC HMI and S7 controllers.
Additionally communications modules are available, providing communications via SMS, time synchronization and position detection, or to create small ethernet networks.

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.

LOGO! 8 basic device with integrated display

LOGO! 8 starting from version FS:04 offers in combination with LOGO! Soft Comfort 8.1 the following new functions:

  • Extented temperature range -20 to 55°C, without condensation LOGO! 8
  • 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!

Siemens LOGO! Logic Module

Description

A wide range of expansion modules allows to set up an individual LOGO! configuration.
The maximum depends on the used basic module.
LOGO! 8:
24 digital inputs, 20 digital outputs, 8 analog inputs and 8 analog outputs!
LOGO! 6 and LOGO! 7:
24 digital inputs, 16 digital outputs, 8 analog inputs and 2 analog outputs!

If you do networking of several LOGO! 8 or LOGO! 7 one configuration can be expanded to overall 88 digital inputs, 80 digital outputs, 40 analog inputs and 18 analog outputs.
LOGO! 6 and LOGO! 7 can also be connected to AS-interface and KNX sytems.

To combine different voltage levels you have to keep the following rule:
The basic module must be a 230 V version followed by 230 V expansion modules. Then an analog module must be used to achieve a galvanic isolation. Right from the analog module further analog modules or 12V / 24 V expansions can be attached.
