# Application Example Traffic Light
## Description
This application example shows how to use the state framework of the package `@simatic-ax/statemachine`. In this example a simple traffic light will be realized.
## Execute the Application Example (AX Code local)
1. Open a command line interface (CLI) and switch to the target folder. Example, if the traget folder is D:\temp
```sh
D:
cd \temp
```
1. Install the application example on your local PC
Run the following commands in a CLI
```sh
apax create @simatic-ax/ae-trafficlight --registry https://npm.pkg.github.com ae-trafficlight
```
Open `AxCode` with
```sh
cd ae-trafficlight
```
install the dependencies with:
```sh
apax install
```
and open AxCode
```sh
axcode .
```
1. If not open, open a terminal (`CTRL+SHIFT+ö`)
1. Start a PLCSIM Advanced Instance (IP: Address 192.168.0.1). To change the IP you'll find information [here](#tips-and-tricks)
1. If not done, download a valid hardware configuration (FW >= 2.9 and IP address 192.168.0.1) to the PLCSIM Advanced Instance. The recommend way is using TIA Portal.
1. Build in download the project to the PLC
```cli
apax dlplc
```
The project will be compiled and downloaded to the PLCSIM Advanced instance
1. Open the monitoring file mon.mon
1. Go online
## Tips and tricks
