First, We must to know these concepts:

Digital Inputs (DI): There are the phisycal and Software connections in PLC of all Control Inputs Elements as Sensors, Pushbuttons, Switches, Limit Switch, Emergency Stop, etc, you can recognize it over the PLC from I1 to I8

Digital Outputs (DO): There are the phisycal and Software connections in PLC of all Control Outputs Elements as Contactors, Control Relays, VFD, you can recognize it down the PLC from Q1 to Q4

CPU -PLC: CPU is the Computer and Brain in any PLC, a PLC almost always have just 1 CPU and then you add Modules to make your PLC bigger, you can identify this where you have Communication PORT (in this case Logo! uses Ethernet and Port RJ45)

Control Elements: There are all the element of the process as Input or Outputs that act directly with the PLC , you can identify with Digital Inputs or Outputs as Sensors, Pushbuttons, Switches, contactors, Relays and More; The process use a lot of Control elements

STEP 1 : NECESSARY ELEMENTS

First we need Hardwares and Software of PLC Logo

The Programmable Relay PLC Logo! need a Software to make the Program that control all our process, so we need these elemments:

Notebook or Portable Computer with CD-USB o CD
PLC Logo! V8 Siemens
Communication Cable Ethernet Cat5e o higher
Software PLC Logo Siemens; Logo Soft Comfort V8.0 or higher
Wiring in 220VAC (We use Logo! 220VAC)

NO problem if we dont have the Original CD, we can Download DEMO VERSION Here Download fast! from Siemens WebPage in "Demosoftware" if we have this demo, we may simulate and create a lot of control projects really perfect to practice

STEP 2: Installing Software or Demo

we have 2 options to install Software; Original or Demo

We can obtain DemoSoftware Free from Siemens Webpage:
Download Demo HERE from Siemens Webpage

Don't forget, you must to be registered in SIEMENS Webpage for download Softwares and Siemens documents

Very Important to consider:

The Version DEMO can use to write all instructions and simule it (great to learn), but YOU DONT upload the program in a PLC Logo!

Logo Soft! Only can be used in Notebooks

The price of the Original CD is around 80 USD and it can be installed in many Computers

Only Original CD can guarantee the perfect works of the PLC

We recommend Windows 8 o higher, it's better in upgrades

STEP 3: Installing LOGO SOFT

Configuring and first steps in PLC LOGO! Siemens

The steps to install Software are:

Insert CD or do Click in SETUP downloades from Siemens Webpage
Choose your Language and Continue
Accept and Continue
Keep the Default Folder and Continue
Choose second round y continue
The Installing is Starting...
Choose "No" because it asked about use "USB Driver", we will use Ethernet Port RJ45
Select first box Launch logo! and "Finish"
Close Window that is opening from Logo!
If you are in this image.... Congratulations! you are inside Logo! Soft Confort
Now we prepare to develop our Software Experience

STEP 4: Preparing Ladder Enviroment

Preparing our Ladder Enviroment to Start to program; Ladder is easiest

In our first project gonna program "Start and Stop" a "Motor", we will work in LADDER, we need:

By Default the logo! starts in KOP enviroment, we will work in LADDER
Select in icon of the image, in the icon it must show "Convert to LAD"
A new Window is open, lo cual evidentemente es diferente a la primera pestaña
Close the KOP Window and now we will focus in languageLADDER
Start to Program!

STEP 5: Programming my project

Programming my first project in Logo! Soft Comfort Siemens

Programming a Start / Stop of a Motor we need to select the follow elements of our software, get it with Mouse:

-| |- Open Contact (Digital Input or DI the same for Start and Stop)
-( )- Coil (Digital Output o DO it activate the Output)
-| |- Open Contact (We use it to mainting with energy the pushbutton, it replaces contacts 13-14 from Contactor)

STEP 6: Configuring Inputs-Outputs

Start to Configure our Digital Inputs and Digital Outputs (0-1)

Get with the Mouse the Contacts and Coil in the Side and rename this in software/hardware, write:

-| |- Start Pushbutton => I1 (Digital Input)
-| |- Stop Pushbutton => I2 (Digital Input)
-( )- Contactor Coil => Q1 (Digital Output)
-| |- Open Contact Coil Q1 => Q1 (Mantain energized)

En el PLC Logo! Todas las Entradas Digitales van siempre en las borneras "I" en la parte superior ; Para las Salidas van en las borneras "Q" en el inferior del PLC

By Default The PLC Logo! got values of Switch for simulations in I1..Ix, we must to work with Momentary Pushbutton, so we go and change the values how show the pictures

STEP 8: Simulating Programmation

We Simulate what happens when we press Start and Stop

OFF

When Q1 is activated, the Output is activated too

VERY IMPORTANT

When we press Start Pushbutton I1 our program will activate Q1

The Contactor is always energized for open contact used in Q1, you don't need connect the open contacts in Contactor typically used 13-14 NO

In this Case the Input I2 is always energized becase it comes from a "Closed Contact" it means that input is always energized, in other case I1 just will be energized when the pushbutton is pressed

For I2 like always is energized, from his normal state -| |- goes to the activated state -|/|-

In the parameters above remember you can find SIM before Start project you Must Simulate here!

STEP 9: Communicating with LOGO!

The moment to connect my Computer and PLC has arrived!

First always rewview IP of PLC, go to => NETWORK => IP ADDRESS, your PC must to be in same Network than PLC (example IP Photo 192.168.0.3), Your PC may has a IP 192.168.0.5

Then we must go and do right click in the side of menu bar in wifi icon "Network and Sharing Center" --> Change Adapter Settings --> Ethernet/Realtek --> Propierties --> Internet Protocol Version 4 TCP/IPv4

In this case our Comunnication is Via Ethernet we will connecting PC and PLC by TCP/IP, so it´s not difficult, you must create a LAN chaging IP Address, it means the Computer and PLC must be in the same Network IP, by default the PC comes with "Automatic IP" :

Our PLC Logo! has by default 2 possible IPs ; 192.168.0.x or 192.168.1.x that's the reason because we must to change the IP in our PC, if we have the same network in PC and PLC we have created a LAN (Local Area Network), third number is a Sub-Network and how PLC Logo! may have 2 possible IPS we try with both; x may be a number 3 a 10, sometimes logo is 1 or 2 (x value)

When we are succefully connected a means we have connected with PLC Logo! for first time!

STEP 10: Finally Start Project

Remember verify your Software and Wire in PLC before start

Verify your Inputs I and Outputs Q
Verify your wire and connections in Logo!
Always Simulate your program before Upload and Runs
UPLOAD your program!

After Upload the program, go to RUN, After this our PLC will work; the screen in PLC will be in color of Picture above....CONGRATULATIONS we have configured for first time our PLC Logo! and then.... just practice

How to Choose a PLC Logo! for my Project?
First you need to know the VOLTAJE to work (24V -12V - 110V - 220V) ; you must to know the digital inputs DI (buttons, emergency stops, etc), the Outputs (Contactors, Relays, VFD); and if you need measure Temperature or more complex parameters, you will need to get Aditional Modules as Analog Modules or Digital Modules

Why Can't Connect with my PLC Logo?
The Communication with PLC Logo! is by ETHERNET (TCP/IP) see the Step 9 Here where we explain how connect by IP; you should change your Sub-network number in your computer, remember Logo! comes with 192.168.1.x or 192.168.0.x must to try with both options
