Do Siemens S7-300 Programmable Logic Controller you do not know, but you should plan now! After a quick series of guides I have together to help you when you started programming Siemens S7-300 PLC.
After loading the software links MPI programs Siemens cable between your computer and the PLC program, SIMATIC Manager to open by clicking the icon on the desktop. Wizard Step 7: "New project" an open window. Easier to use the wizard to your PLC installation media, but I chose to take another scene track. I thought I'd learn more that way. So, close the window Step 7 Wizard by clicking Cancel. If all other windows or open projects, close them. We're starting a whole new program.
Create a new project by clicking the New Project button on the toolbar top left corner of the screen.
The project opens a new window. Here you will find all the existing programs on your computer. Bottom of the window, you can see the name: input form. Type all you want your new project name and click OK.
A new window will open showing the name of the project head. You can also project a window on the left side of the screen at the top. Right-click your project and select "Add a new object." Select the device you are programming. We will be using the SIMATIC 300 station selection so choose.
Now you can window SIMATIC 300 appears on the right side of the screen. It should be highlighted in blue. Click anywhere in the window of the blue go away. Double SIMATIC 300 will pass to the left window "hardware will" be left pane.
Double-click "Hardware" and two (maybe three) will open a new window. SIMATIC 300 will be left - (the name of the project). Window of opportunity to be a partial catalog.
Look at the left pane, the parts catalog, click the plus sign next to SIMATIC 300.
Click the plus sign next to a rack - 300. Click and drag the train to the left window. Now you can appear in the window slots. This is where our PLC components made.
We will be first choice in our laboratory. Looking at the parts catalog, 300 SIMATIC tree, select the processor you use. We are using CPU - 300 So sign click the connection with the option.
Now look at top left front of your PLC. This is where you will find the model of PLC. I'll use CPU313C DP-2, for example, is a model that I use PLC.
Get your catalog processor parts click the plus sign. You can share some numbers now.
Look back to your PLC. Find the door covering the MPI port. This will be the bottom left of the Legislative Council. At the bottom of the door you'll find the part number. I use a few parliamentary 6CF03 For example, 313-0AB0.
Get the number of parts catalog participated. Please note that other folder. Open it to v2.0 and V2.6 will see you. A look back at the legislative council to open the door covering the port MPI, and the right to see the V2.6.3 MPI port.
Back to the parts catalog and click V2.6. Notice how the slot in the left window to draw attention to green. I believe it's # 2 slot. (# 1 slot reserved for power supplies.) It's when you drag and drop your processor. (Did not notice the software to allow you the other processor slot, but slots # 2.)
When you release the mouse button over the No. 2 slot, will open a new window, "Properties - PROFIBUS interface." New window opens, click New, click OK, and then click OK again. We have not set the network during this period.
Now you can do with your CPU hardware costs are listed.
Double click on the slot that the list DI16/DO16 (Digital I / O and digital).
A window with three tabs will open. The first tab, General, addresses the second tab will be entering the third tab.
Open the tab "Address." We must change the default address. This is done by unchecking the default button on the system switch 124 (or whatever your address) to 0. This is the inputs and outputs.
We need now to change the address of the node. Back to the window when you click DI16/DO16 twice double click on Slot 2, CPU 313-2DP time.
313C-2DP window will be apartments - CPU open.
Look at the window a little more than half way to find the area of user interface and click Properties. Another window, "Properties - MPI interface of CPU 313-2DP to be open." Change of address to serve your specific criteria. I know that my laptop, I use my PLC program, always focused on PLC 1 and my goal is usually focused on 2. You must be the same.
Now click on the MPI (1) and click OK. Click OK again to close the Properties window.
To save process by clicking the icon located on the left side toolbar.
Download the hardware configuration of the Palestinian Legislative Council, by clicking on the download icon located on the toolbar.
A window titled "Select a target module should be" open. Click OK.
Another window titled "Select Node Address will be open." You should see your address listed for the PLC node you are working as you set it at all before. If a similar relationship click, click any node address and click OK.
Back SIMATIC Manager (by clicking the taskbar tab.)
Click Options. Select Interface Set PG / PC. Choose cuibheoir computer (Auto).
Click Properties. A new window will open, which reflects automatic detection profile business or local connection. Click Local, and select USB connection. Now, I select automatic address and bus profile changed to 30. Now you can test your connection by clicking Start, detection network. If the new window opens, displaying = Style MPI network, transmission 187.5kbps level, you set your communication with S7 300. Click Close. Click OK. Click OK.
Now it's time to start the program. Looking out the window SIMATIC Manager, click the plus sign near the SIMATIC 300 (1), click the plus sign next click 313C-2DP, CPU on the plus sign next to a S7 (1). Now click on the blocks you will see a window appear OB1 data right on the screen.
Double click will OB1 and open a new window named Properties - Block Organization
Here you can choose how you want the program, the child (ladder), STL (statement list), or FBD (function block diagram). Choose where you want to use, and then click OK.
Double clicking again will OB1 child / STL / FBD program window is open.
Now you can start programming.
