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.

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

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

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.
