Getting used to DataLogger functions

Duration 04m:00s    Resolution HDTV 720p    audio language English    subtitles language English

Frank Walde tells all you need to know for starters about the DataLogger. Frank is Senior Project Manager in the Product Management PLCnext Runtime System at Phoenix Contact Electronics in Bad Pyrmont, Germany. 

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

Configuring for "Record on time"

Duration 08m:31s    Resolution HDTV 720p    Audio language English    Subtitles language English

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:

DataLogger with OPC UA Historical Data Access

Duration 04m:41s   resolution HDTV 720p    audio language English    subtitles language English

Now it's getting historical! Recruiting the embedded OPC UA server of the PLCnext Technology Runtime, we will set up our data ports to be historizing 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"

Duration 07m:59s    Resolution HDTV 720p    Audio language English    Subtitles language English

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

DataLogger configuration with PLCnext Engineer 

Duration 06m:16s   resolution HDTV 720p    audio language English    subtitles language English

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 be historizing all values.

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