How to Program a Siemens S7-300 Programmable Logic Controller

Do you do have a Siemens S7-300 Programmable Logic Controller that you’re not accustomed to but you should program it NOW! Pursuing is a quick set of Guidelines I’ve set collectively that can assist you get started programming a Siemens S7-300 PLC.

Immediately after loading the programming computer software and connecting a Siemens MPI cable involving your programming computer and the PLC, open up SIMATIC Manager by clicking the icon to the desktop. The Phase 7 Wizard: “New Job” window will open. It’s simpler to use the Wizard to setup communications along with your PLC, but I selected to go ahead and take scenic route. I figured I might learn more using this method. So, close the STEP seven Wizard window by clicking Cancel. If you can find almost every other windows or tasks open up, shut them. We want to begin with a completely new system.

Create a new job by clicking The brand new task button on the toolbar within the upper left corner within your screen.

The brand new Undertaking window opens. Below you will see any present plans Found on your own Computer system. Close to the bottom from the window, you will note the Name: input kind. Style regardless of what you would like to title your new venture and click on Okay.

A completely new window will open up demonstrating the identify of your respective job at the very best. You will also see your task while in the window over the left hand side in the monitor at the top. Right click on your venture and pick out “Insert New Object”. Select the gadget you may be programming. We will probably be using the SIMATIC three hundred Station so opt for that collection.

You might now see SIMATIC 300 appear in the right window within your screen. It should be highlighted blue. Simply click wherever within the window to make the blue go away. Double click on SIMATIC three hundred and it’ll move for the still left window and “Components” will look in the proper window.

Double click on “Hardware” and two (possibly 3) new windows will open. Over the still left will be SIMATIC 300 – (the name of your venture). The window on the correct will be the catalog of pieces.

Appear in the proper window, the areas catalog, and click the additionally indicator beside SIMATIC 300.

Click the additionally signal beside RACK – 300. Simply click and drag the Rail on to the still left window. You may now see the Slots window seem. This is when We are going to position our PLC elements.

We’re going to to start with pick out our CPU. Thinking about the sections catalog, inside the SIMATIC three hundred tree, select the CPU that you are utilizing. We’ve been using the CPU – three hundred so click the moreover sign beside that preference.

Now consider the entrance major left of your respective PLC. This is when you will see the PLC design. I’ll use CPU313C-2 DP for instance given that Here is the model PLC that I use.

Uncover this CPU inside your pieces catalog and click on the furthermore signal. You might now see some component figures.

Glance back again at your PLC. Identify the door covering the MPI port. This will be the base remaining side in the PLC. At the bottom in the door you will discover the aspect selection. The section number for the PLC I’m applying for example is 313-6CF03-0AB0.

Locate this portion number within the pieces catalog. You will detect this is an additional folder. Open up it and you’ll see V2.0 and V2.six. Seem again for the PLC, open the door masking the MPI port, and appropriate over the MPI port you will note V2.6.3.

Go back to the pieces catalog and click on V2.six. Recognize how a slot within the still left hand window will emphasize green. I feel it will be slot #2. (Slot #1 is reserved for ability supplies.) This is when you are going to drag and drop your CPU. (Detect the software program will never Permit you place the CPU in another slot but slot #two.)

After you launch the mouse button around slot #two, a completely new window will open up, “Houses – PROFIBUS interface”. Click on new, a different window opens, click on Ok, after which click Alright all over again. We aren’t organising a network presently.

You can now see your CPU and involved hardware outlined.

Double simply click while in the Slot that checklist your DI16/DO16 (Electronic Input/Electronic Output).

A window with a few tabs will open. The first tab are going to be Normal, the second tab will be Addresses as well as third tab might be Inputs.

Open the tab “Addresses”. We have to alter the default addresses. Make this happen by unchecking the Technique Default button and altering 124 (or whichever address you might have) to 0. Do this for the two the Inputs and Outputs.
