How to System a Siemens S7-300 Programmable Logic Controller

Do you have a Siemens S7-300 Programmable Logic Controller that you are not familiar with but you will need to software it NOW! Pursuing is a quick established of directions I have put with each other to aid you get started programming a Siemens S7-300 PLC.

Immediately after loading the programming software and connecting a Siemens MPI cable in between your programming laptop or computer and the PLC, open SIMATIC Supervisor by clicking the icon on the desktop. The Move 7 Wizard: “New Undertaking” window will open. It is simpler to use the Wizard to setup communications with your PLC, but I chose to choose the scenic route. I figured I would study a lot more this way. So, near the Action 7 Wizard window by clicking Terminate. If there are any other windows or initiatives open up, near them. We want to start off with a thoroughly new program.

Create a new undertaking by clicking the new challenge button on the toolbar in the upper left corner of your display.

The New Undertaking window opens. Listed here you will see any present applications located on your computer. Near the base of the window, you will see the Name: enter type. Style no matter what you want to identify your new challenge and click Okay.

A new window will open demonstrating the name of your venture at the top. You will also see your task in the window on the remaining hand side of the screen at the top rated. Proper click on your venture and decide on “Insert New Item”. Choose the machine you will be programming. We will be utilizing the SIMATIC 300 Station so opt for that variety.

You will now see SIMATIC 300 surface in the ideal window of your screen. It should be highlighted blue. Simply click everywhere in the window to make the blue go absent. Double click on SIMATIC 300 and it will go to the still left window and “Hardware” will appear in the correct window.

Double click on “Components” and two (maybe three) new windows will open. On the left will be SIMATIC 300 – (the name of your venture). The window on the proper will be the catalog of parts.

Glimpse in the correct window, the areas catalog, and click the furthermore indication beside SIMATIC 300.

Click on the furthermore indicator beside RACK – 300. Click on and drag the Rail onto the remaining window. You will now see the Slots window seem. This is where we will place our PLC parts.

We will very first pick our CPU. Looking at the areas catalog, in the SIMATIC 300 tree, pick the CPU that you are making use of. We are working with the CPU – 300 so simply click the as well as indication beside that selection.

Now search at the front leading remaining of your PLC. This is wherever you will obtain the PLC product. I will use CPU313C-2 DP as an example given that this is the product PLC that I use.

Locate this CPU in your pieces catalog and click the additionally indicator. You will now see some element quantities.

Seem back at your PLC. Identify the door covering the MPI port. This will be the base still left side of the PLC. At the bottom of the door you will discover the portion selection. The element quantity for the PLC I am employing as an instance is 313-6CF03-0AB0.

Discover this portion variety in the pieces catalog. You will see this is another folder. Open it and you will see V2. and V2.6. Look back at the PLC, open up the doorway masking the MPI port, and proper previously mentioned the MPI port you will see V2.6.3.

Go again to the pieces catalog and click V2.6. Recognize how a slot in the left hand window will highlight environmentally friendly. I believe that it will be slot #2. (Slot #1 is reserved for electricity supplies.) This is exactly where you will drag and drop your CPU. (See the software package will not enable you put the CPU in any other slot but slot #2.)

When you launch the mouse button over slot #2, a new window will open, “Attributes – PROFIBUS interface”. Simply click new, a new window opens, click Okay, and then simply click Ok once again. We are not location up a network at this time.

You will now see your CPU and involved components shown.

Double simply click in the Slot that record your DI16/DO16 (Electronic Enter/Digital Output).

A window with 3 tabs will open up. The very first tab will be Typical, the next tab will be Addresses and the 3rd tab will be Inputs.

Open the tab “Addresses”. We have to have to modify the default addresses. Do this by unchecking the Method Default button and changing 124 (or regardless of what deal with you have) to . Do this for each the Inputs and Outputs.

We now will need to transform the Node Deal with. Go again to the window where by you double clicked DI16/DO16 and double click in Slot 2, the CPU 313-2DP slot.

The Houses – CPU 313C-2DP window will open.

Glimpse down the window a small above 50 percent way and find the Interface location and simply click on Attributes. A different window, “Qualities – MPI interface CPU 313-2DP” will open up.
Change the tackle to meet up with your precise requirements. I know that my laptop, which I am working with to system my PLC, is normally addressed as 1 and my concentrate on PLC is ordinarily tackled as 2. You will in all probability be the exact same.

Now simply click MPI(1) and click Alright. Click on Okay once more to close the Properties window.

Help you save and Compile by clicking the icon positioned on the left of the toolbar.

Obtain the hardware configuration to the PLC by clicking the obtain icon found on the toolbar.

A window titled “Pick out Target Module” should really open. Simply click Ok.

A different window titled “Decide on Node Deal with” will open up. You need to see mentioned your node tackle for the PLC you are operating with as you configured it in a former phase. If not, simply click look at and click on on whichever node deal with seems and click Ok.

Swap again to SIMATIC supervisor (by clicking the tab on the taskbar).

Click on on Alternatives. Opt for Set PG/Personal computer Interface. Choose Computer Adapter (Automobile).

Click on Houses. A new window will open, exhibiting either Computerized Bus Profile Detection or Regional Connection. Click on Area Link and choose USB. Now choose Automatic Bus Profile Detection and transform the tackle to 30. You can look at your link now by clicking Start out Community Detection. If a new window opens displaying Community Variety = MPI, Transmission Fee = 187.5kbps, you have set up communications with your S7-300. Click Near. Simply click Alright. Simply click Okay.

It is now time to begin programming. On the lookout at the SIMATIC Supervisor window, click the additionally indicator found beside SIMATIC 300(1), simply click the as well as indication beside CPU 313C-2DP, simply click the in addition signal beside S7 Plan(1). Now click on on Blocks and you will see Process data and OB1 surface in the appropriate window on your display.

Double simply click on OB1 and a new window will open named Qualities – Organization Block

Below you can pick how you want to system, in LAD (ladder), STL (statement record), or FBD (functionality block diagram). Opt for which you want to use and click Alright.

Double click OB1 again and the LAD/STL/FBD programming window will open.

You can now start out programming.
