As a newbie, please don't skip this introduction so we can get deeper into it in the following two videos without losing you.

In this video, we are setting up a program that logs data from a set of ports into an SQLite database, so we can access those logs from our host computer. Prerequisites here:

Download the DataLogger Service configuration file from the PLCnext repository on GitHub.
To go along with these instructions, you have to connect to an OPC UA® Server.
Just in case you need help with that, here's how to set up an OPC UA server connection with PLCnext Engineer in general.

Now it's getting historical! Recruiting the embedded OPC UA® server of the PLCnext Technology Runtime, we will set up our data ports to historicize all values.

We will be using the UaExpert client from Unified Automation in this session, so make sure you have that installed already.

Configuring for "Record on change"

In this video, we are configuring a DataLogger session with a small program to only record changes of the variable values. This is done by means of a .config file which we're editing to our needs.
Prerequisites: Download the DataLogger Service configuration file from the PLCnext repository on GitHub.

Starting with firmware 2020.6 and PLCnext Engineer 2020.6, you can now set up and configure a DataLogger session by means of the PLCnext Engineer interface. Frank shows the procedure for a typical use case involving variables to be read out via OPC UA®.

After that, we will recruit the embedded OPC UA® server of the PLCnext Technology Runtime, set up our data ports to historicize all values.

We will be using the UaExpert client from Unified Automation in this session, so make sure you have that installed already.
