Use PLCnext to WakeOnLan (WoL) Your PC

What Is Wake-on-LAN?

Wake-on-LAN (sometimes abbreviated WoL) is an industry standard protocol for waking computers up from a very low power mode remotely. The definition of “low power mode” has changed a bit over time, but we can take it to mean while the computer is “off” and has access to a power source.

We are going to use wakeonlan python package
to execute the UDP datagram and wake destination MAC address

Before we can do this we need to install ipk., Python and the pip package manager on the controller.
Ensure that you have a Ethernet connection.
