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 we need to create a new project by clicking on the “new” icon on the toolbar to open the “new project” window.
In this window we enter a name for our project in the “name” field.The path to our saved project is shown in the “storage location.”
However we can use the browse button to navigate to a different location other than the default.

7.We need to install a “power supply” in the first slot to power our PLC modules and turn them on.To do this we open this “PS 300” folder and double click on this two-ampere power supply to insert it into the first slot of the rack

8.In the second slot of the rack we always insert the “CPU” module.To select the desired module we open this “CPU 300” folder, 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 click on the relevant part number to insert it into the second slot in the rack.We can add rest of the modules in similar way.
9.The addresses of the digital input module range from byte zero to byte number 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 output module range from byte number 4 through to byte number 5 so there are 16 addresses that we can use for this module starting at “Q 4.0” continuing through to “Q 5.7. Finish the configuration and download it to PLC
