Node-RED security

If you did not set up login using the following guide, you expose yourself to a risk of unauthorized access to the Unipi controller. That may lead to potentially dangerous changes resulting in downtimes or limitations. At the worst, unauthorized tampering can damage connected technologies or endanger personnel at installation sites.

That said, it is very important to have your system secured every time you create a new project.

As you will communicate with the PLC using the SSH protocol, you need to know the PLC's IP address and to have an SSH client installed on your PLC. Among the most frequently used programs is the PuTTy application - if you don't have it already, follow this guide. Alternatively, you can transfer files between your PC and the PLC via the [https://winscp.net/eng/download.php|WinSCP utility]]. Login is the same as for SSH.

After that, just follow this guide on the official Node-RED webpage.
