pocketncopcua

Configfile for the default deployment over pycharm

• Create a shell script such as sudo nano /usr/bin/opcuaserver.sh check the path of your deployment:

    #!/bin/bash
  
    # start the python programm with sudo because of deployment config
    sudo python /home/pocketnc/opcserver/main.py
  

Make the script executabel: sudo chmod +x /usr/bin/opcuaserver.sh

Note that the first line is critical.

• Create a service file in /lib/systemd/opcserver.service such as:

    [Unit]
    DescriptionPPocketNC OPC UA Server
  
    [Service]
    Type=simple
    ExecStart=/usr/bin/opcuaserver.sh
  
    [Install]
    WantedBy=multi-user.target
  

• Create a symbolic link between your script and a special location under /etc:

    ln -s /lib/systemd/opcserver.service /etc/systemd/system/opcserver.service
  

• Make systemd aware of your new service

    systemctl daemon-reload
    systemctl enable opcserver.service
    systemctl start opcserver.service
  

• Reboot the BeagleBone Black to see your script in action

• If you wish to control the service at runtime, you can use systemctl commands:

    systemctl status opcserver.service
    systemctl stop opcserver.service
    systemctl start opcserver.service
    systemctl disable opcserver.service
