Siemens S7 300 and STEP 7 PLC program using SIMATIC Software

Siemens S7 300 and STEP 7 PLC program

1.Open SIMATIC Manager. SIMATIC Manager is a program which manages subprograms of STEP 7 .
2.To start our programming first gear we need to create a new project by clicking on the “ new ” icon on the toolbar to open the “ raw project ” window .
In this window we enter a name for our plan in the “ name ” field.The path to our saved undertaking is shown in the “ storehouse localization. ”

however we can use the browse button to navigate to a unlike placement other than the default option .

3.After creating the visualize we click on its name to highlight it.then from the “ cut-in ” menu we select one of these “ stations ” pendent upon the master system that we intend to use .

4.After selecting “ Station 300 ” we see that a subgroup named “ SIMATIC 300 ” has been added to our project .

5.Next we click on this “ hardware ” icon which takes us to the hardware .

so that we can configure the modules we need for the PLC.Our PLC is an “ S7 300″ .

so we need to select the relevant modules from “ SIMATIC 300 ” subgroup here .

6.First of all we need a rack into which we will mount the modules .

To insert the rack, open the “ rack 300 ” and bivalent snap on the “ rail ” to add it to the exit window.As you can see this torment has 11 slots .

7.We need to install a “ power provision ” in the first slot to power our PLC modules and turn them on .
To do this we open this “ PS 300 ” folder and doubly suction stop on this two-ampere power provide to insert it into the first slot of the single-foot

8.In the second slot of the rack we always insert the “ CPU ” module.To select the desire module we open this “ CPU 300 ” booklet, which opens to show us all types of “ 300 CPUs. ”
We want to select a “ 316 CPU ”, so we need to open this “ CPU 316 ” folder and snap on the relevant depart count to insert it into the second slot in the rack.We can add stay of the modules in like way .
9.The addresses of the digital input signal module range from byte zero to byte total one means that the addresses we can use in this module for our program start at “ I 0.0 ” for the first input and continue through to “ I 1.7 ” for the last input .

similarly you can see the addresses of our digital end product module scope from byte number 4 through to byte number 5 so there are 16 addresses that we can use for this faculty starting at “ Q 4.0 ” continuing through to “ Q 5.7. Finish the shape and download it to PLC

10.Before downloading Click on deliver and roll up icon to save it.then we click on this download icon.This brings up a window where we need to select the CPU to which we want to download the shape and then click “ OK ” .

In the next window click on “ view ” and then select the appropriate “ MPI ” address, and after clicking “ OK ” the configuration will download to the CPU

now, having completed the configuration we can check the project tree and see that a subgroup with the like name as the CPU has been added there .
