Preparation

Requirement: An up-to-date Linux operating system (for example, Debian or Ubuntu) must be installed on your controller and an SSH server must be installed and activated.

To check whether the SSH server is active, execute the following command on your controller:

sudo systemctl status ssh

When the SSH server is active, the output should look like this:

ssh.service - OpenBSD Secure Shell server 
    Loaded: loaded (/lib/systemd/system/ssh.service; enabled; preset: enabled)     
    Active: active (running) since [...]       
    Docs:   man:sshd(8)             
            man:sshd_config(5)   
  Main PID: 741 (sshd)      
    Tasks:  1 (limit: 18876)     
    Memory: 10.4M        
    CPU:    12.778s     
    CGroup: /system.slice/ssh.service             
            └─741 "sshd: /usr/sbin/sshd -D [listener] 0 of 10-100 startups"

If the SSH server is not activated, then you can activate the server permanently with the following command: sudo systemctl enable ssh. Then check whether the service is active as described above.

If you want to use CODESYS Virtual Control for Linux SL, then an up-to-date version of the following software must also be installed:

Use the CODESYS Installer to install an up-to-date version of CODESYS Development System and the CODESYS package for the controller where you want to use the runtime system.

You need at least the following packages:
