#Siemens step 7 tutorial install#

Now, having completed the configuration we can check the project tree and see that a subgroup with the same name as the CPU has been added there.ДЎ1.Now we can write our program in a block named 'OB 1'We can find the вЂњOB 1вЂќ by opening

Menu we select one of these 'stations'dependent upon the control system that we intend toД¤.After selecting вЂњStation 300вЂќ we see that a subgroup named вЂњSIMATIC 300вЂќ has been added to our project.ДҐ.Next we click on this вЂњhardwareвЂќ icon which takes us to the hardware so that we can configure the modules we need for the PLC.Our PLC is an вЂњS7 300' so we need to select the relevant modules from вЂњSIMATIC 300вЂќ subgroup here.Д¦.First of all we need a rack into which we will mount the modules.To insert the rack, open the вЂњrack 300вЂќ and double click on the вЂњrailвЂќ to add it to the left window.As you can see this rack has 11 slots.Д§.We need to install a вЂњpower supplyвЂќ in the first slot to power our PLC modules and turn them on.To do this we open this вЂњPS 300вЂќ folder and double click on this two-ampere power supply to insert it into the first slot of the rackДЁ.In the second slot of the rack we always insert the вЂњCPUвЂќ module.To select the desired module we open this вЂњCPU 300вЂќ folder, which opens to show us all types of вЂњ300 CPUs.вЂќ We want to select a вЂњ316 CPUвЂќ, so we need to open this вЂњCPU 316вЂќ 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.Д©.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 вЂњI 0.0вЂќfor the first input and continue through toвЂњI 1.7вЂќ 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 вЂњQ 4.0вЂќ continuing through to вЂњQ 5.7.Finish the configuration and download it to PLCДЎ0.Before downloading Click on save and compile 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 configuration and then click вЂњOKвЂќ.In the next window click on вЂњviewвЂќ and then select the appropriate вЂњMPIвЂќ address, and after clicking вЂњOKвЂќ the configuration will download to the CPU. SIMATIC Manager is a program which manages subprograms of STEP 7.Дў.To start our programming first we need to create a new project by clicking on the вЂњnewвЂќ icon on the toolbar to open the вЂњnew projectвЂќ window.In this window we enter a name for our project in the вЂњnameвЂќ 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.ДЈ.After creating the project we click on its name to highlight it.then from the вЂњinsertвЂќ
