Logging Sensor Data From Siemens S7 PLC To MariaDB Database

In this video we're creating an application to measure the temperature and humidity in a room every 5 seconds and store it in a database.
To make the application we're using a Siemens S7 1200 PLC, a NUC (NUC6CAYH) running our connector service and a synology drive (DS410) running our MariaDB database.
