1. Network Settings for ETH1

Configure the network settings for ETH1 as follows:

• IP Address: xx.x.x.xxx (Set a specific IP)
• Gateway: 10.1.1.1
• DNS Nameservers: 8.8.8.8

Ensure these settings are correctly applied in the Network Settings.

2. Screen Rotation Configuration

Adjust the screen orientation:

• Navigate to Start -> Preferences -> Touch Screen Settings.
• Set eDP-1 to 90° rotation.
• Click Apply, then Save, and select System-wide to apply changes.

3. PLC IP Configuration

In the Visu settings, configure the IP address for the PLC:

• Go to Visu Settings -> IP_ARwin.
• Set the required IP address for PLC communication.

4. DEV PC IP Verification

Check the IP of the DEV PC:

• This IP will be required for Selenium setup. Make sure to note it down.

5. Disable wjStartup.service

To prevent the visual interface from auto-starting, disable the wjStartup.service:

systemctl --user stop wjStartup.service
systemctl --user disable wjStartup.service

6. Install Java

Update the package list and install Java Runtime Environment (JRE) and Java Development Kit (JDK):

sudo apt update
sudo apt install default-jre
sudo apt install default-jdk
java -version

7. Download Selenium Server

Download the Selenium server (suggested on a separate PC, then transfer via USB if needed):

• Download link for Selenium Server: https://www.selenium.dev/downloads/
• Copy the downloaded file to Linux: /woojin/ATest

8. Edit wjStartUp.sh

Edit the wjStartUp.sh file in /woojin to allow Selenium to start with Linux:

1. Open the file /woojin/wjStartUp.sh.
2. Add the following lines to start the Selenium server:

# Start selenium-server
java -jar /woojin/ATest/selenium-server-4.23.0.jar node --hub http://<IP.Dev.PC>:4444

Replace <IP.Dev.PC> with the actual IP address of the DEV PC.

9. Download ChromeDriver

To enable Selenium to control Chromium:

1. Ensure that chromium --version on Linux matches chromedriver --version.
2. Download the ChromeDriver (it may be easier to download on another PC and transfer via USB):
   • ChromeDriver Download Link: https://googlechromelabs.github.io/chrome-for-testing/
3. Place it in Linux at /woojin/ATest and run the following commands:

unzip /woojin/ATest/chromedriver-linux64.zip
cd chromedriver-linux64
sudo mv chromedriver /usr/local/bin/
sudo chmod +x /usr/local/bin/chromedriver
chromedriver --version

10. Enable SSH on Linux

Enable SSH for remote access:

sudo apt update
sudo apt install openssh-server
sudo systemctl enable ssh
sudo systemctl start ssh
sudo systemctl status ssh
sudo ufw allow ssh
sudo ufw enable

To connect from the Dev PC:

ssh woojin@<IPVisuPC>

Replace <IPVisuPC> with the Linux PC’s IP.

11. Install VNC Server

To enable remote graphical access via VNC:

1. Update packages and install x11vnc:

sudo apt update
sudo apt install x11vnc

To start the VNC server manually:

x11vnc

To stop the VNC server manually:

pkill x11vnc
