 # Introduction If you have TIA Portal but don't have any machine to program, then this project is for you. It is a 3D simulation of *Packing Machine* which is controlled by *Siemens S7-PLCSIM* (virtual PLC). So basically you can program PLCSIM using TIA Portal, and test the program visually in the 3D graphical simulation. # Prequisites - **Windows** operating system - Installed [**TIA Portal**](http://www.industry.siemens.com/topics/global/en/tia-portal/Pages/default.aspx) and [**Simatic S7-PLCIM**](http://w3.siemens.com/mcms/simatic-controller-software/en/step7/simatic-s7-plcsim/pages/default.aspx) (both tested with V13) - Download and unzip [**NetToPLCSim**](https://sourceforge.net/projects/nettoplcsim/files/latest/download) - Clone/download this repository # Get Started It is important to do the following steps in order they are written in. ## NetToPLCSim 1. Restart your computer (optional, read the **Note** below). 2. Start **NetToPLCsim.exe** as Administrator. 3. If dialog window about Port 102 pops up, click on Yes to make the port available. 4. In NetToPLCSim open the **defualt.ini** file contained in this repo. 5. Click on *Start Server* button. >**Note:** The computer restart is not needed if you haven't started TIA Portal or PLCSIM yet since the computer power-up.  ## PLCSIM 1. Start **PLCSIM**. 2. Create new *S7-1200* project or open existing one. ## TIA Portal 1. Start **TIA Portal**. 2. Open the **PackingMachine_Clean** project contained in this repo. 3. Download the project to running PLCSIM instance. ## Packing Machine App 1. Start the **PackingMachine.exe** app contained in this repo. 2. Choose screen resolution and hit Play button. 3. Click on the *Connect* button in lower left corner. 4. If everything goes ok, it should change its text to *Disconnect* (which means it is successfully connected to PLCSIM).  # How to Program Now you can *Save as* the opened PackingMachine_Clean TIA Portal project under different name and start programming. The list of Inputs and Outputs can be found in the same-named PLC Tag tables. Even in the simulation app after pressing Esc or Space and clicking on the Help icon, a list of keyboard shortcuts is present which can be used to manually trigger individual outputs (only when Disconnected from PLCSIM).  After pressing **Esc** a pause menu is triggered. You can also use **Space** shortcut to restart the scene.  # Support If you have any questions, feel free to open New Issue. # Special Thanks to * **Davide Nardella** for creating Sharp7 * **Thomas Wiens** for creating NetToPLCSim * **Michele Cattafesta** (www.mesta-automation.com) for [great tutorial](https://www.mesta-automation.com/how-to-write-a-siemens-s7-plc-driver-with-c-and-sharp7) on Sharp7
