Do you have a Siemens S7-three hundred Programmable Logic Controller that you are not familiar with but you have to have to plan it NOW! Next is a quick set of recommendations I have place alongside one another to support you get started out programming a Siemens S7-three hundred PLC.
Following loading the programming software package and connecting a Siemens MPI cable involving your programming personal computer and the PLC, open SIMATIC Manager by clicking the icon on the desktop. The Stage seven Wizard: “New Task” window will open. It is much easier to use the Wizard to set up communications with your PLC, but I chose to get the scenic route. I figured I would discover far more this way. So, shut the Stage seven Wizard window by clicking Cancel. If there are any other windows or tasks open, shut them. We want to start with a fully new plan.
Create a new task by clicking the new task button on the toolbar in the higher remaining corner of your display screen.
The New Task window opens. In this article you will see any present packages situated on your personal computer. In close proximity to the base of the window, you will see the Identify: input form. Kind whatever you want to identify your new task and simply click Okay.
A new window will open demonstrating the identify of your task at the major. You will also see your task in the window on the remaining hand facet of the display screen at the major. Right simply click your task and decide on “Insert New Object”. Choose the unit you will be programming. We will be making use of the SIMATIC three hundred Station so decide on that range.
You will now see SIMATIC three hundred appear in the correct window of your display screen. It must be highlighted blue. Simply click any where in the window to make the blue go away. Double simply click SIMATIC three hundred and it will shift to the remaining window and “Hardware” will appear in the correct window.
Double simply click “Hardware” and two (maybe a few) new windows will open. On the remaining will be SIMATIC three hundred – (the identify of your task). The window on the correct will be the catalog of areas.
Appear in the correct window, the areas catalog, and simply click the plus sign beside SIMATIC three hundred.
Simply click the plus sign beside RACK – three hundred. Simply click and drag the Rail onto the remaining window. You will now see the Slots window appear. This is where by we will put our PLC parts.
We will 1st decide on our CPU. Wanting at the areas catalog, in the SIMATIC three hundred tree, decide on the CPU that you are making use of. We are making use of the CPU – three hundred so simply click the plus sign beside that selection.
Now seem at the front major remaining of your PLC. This is where by you will uncover the PLC model. I will use CPU313C-2 DP as an instance given that this is the model PLC that I use.
Obtain this CPU in your areas catalog and simply click the plus sign. You will now see some element figures.
Appear back again at your PLC. Identify the door covering the MPI port. This will be the base remaining facet of the PLC. At the base of the door you will uncover the element variety. The element variety for the PLC I am making use of as an instance is 313-6CF03-0AB0.
Obtain this element variety in the areas catalog. You will notice this is a further folder. Open up it and you will see V2. and V2.six. Appear back again at the PLC, open the door covering the MPI port, and correct higher than the MPI port you will see V2.six.three.
Go back again to the areas catalog and simply click V2.six. Detect how a slot in the remaining hand window will spotlight inexperienced. I imagine it will be slot #2. ( Slot #one is reserved for power materials.) This is where by you will drag and fall your CPU. (Detect the software package will not enable you place the CPU in any other slot but slot #2.)
When you launch the mouse button over slot #2, a new window will open, “Qualities – PROFIBUS interface”. Simply click new, a new window opens, simply click Okay, and then simply click Okay all over again. We are not placing up a network at this time.
You will now see your CPU and associated hardware outlined.
Double simply click in the Slot that checklist your DI16/DO16 (Electronic Input/Electronic Output).
A window with a few tabs will open. The 1st tab will be Common, the 2nd tab will be Addresses and the third tab will be Inputs.
Open up the tab “Addresses”. We have to have to change the default addresses. Do this by unchecking the Procedure Default button and changing 124 (or whatever handle you have) to . Do this for equally the Inputs and Outputs.
We now have to have to change the Node Tackle. Go back again to the window where by you double clicked DI16/DO16 and double simply click in Slot 2, the CPU 313-2DP slot.
The Qualities – CPU 313C-2DP window will open.
Appear down the window a little over half way and uncover the Interface region and simply click on Qualities. A further window, “Qualities – MPI interface CPU 313-2DP” will open. Adjust the handle to fulfill your particular criteria. I know that my notebook, which I am making use of to plan my PLC, is always addressed as one and my focus on PLC is generally addressed as 2. You will likely be the same.
Now simply click MPI(one) and simply click Okay. Simply click Okay all over again to shut the Qualities window.
Help you save and Compile by clicking the icon situated on the remaining of the toolbar.
Obtain the hardware configuration to the PLC by clicking the obtain icon situated on the toolbar.
A window titled “Select Goal Module” must open. Simply click Okay.
A further window titled “Select Node Tackle” will open. You must see outlined your node handle for the PLC you are working with as you configured it in a past step. If not, simply click view and simply click on whatever node handle seems and simply click Okay.
Change back again to SIMATIC supervisor (by clicking the tab on the taskbar).
Simply click on Alternatives. Choose Set PG/Laptop Interface. Choose Laptop Adapter (Automobile).
Simply click Qualities. A new window will open, displaying possibly Computerized Bus Profile Detection or Nearby Connection. Simply click Nearby Connection and decide on USB. Now decide on Computerized Bus Profile Detection and change the handle to thirty. You can check your connection now by clicking Begin Network Detection. If a new window opens displaying Network Kind = MPI, Transmission Rate = 187.5kbps, you have established communications with your S7-three hundred. Simply click Near. Simply click Okay. Simply click Okay.
It is now time to start programming. Wanting at the SIMATIC Manager window, simply click the plus sign situated beside SIMATIC three hundred(one), simply click the plus sign beside CPU 313C-2DP, simply click the plus sign beside S7 Program(one). Now simply click on Blocks and you will see Procedure data and OB1 appear in the correct window on your display screen.
Double simply click on OB1 and a new window will open named Qualities – Business Block
In this article you can decide on how you want to plan, in LAD (ladder), STL (statement checklist), or FBD (functionality block diagram). Choose which you want to use and simply click Okay.
Double simply click OB1 all over again and the LAD/STL/FBD programming window will open.
