How to Log OPC UA Data to a Database


Open Automation Software Tags can be defined to connect to OPC UA Servers with the built in OPC UA Driver Interface. This tutorial walks you though downloading and installing OAS, configuring an OPC UA driver, configuring tags and logging them to a database. Supported databases include SQL Server, Oracle, Access, PostgreSQL, Cassandra, MongoDB, MariaDB, SQLite, InfluxDB, MySQL, SQL Azure, Amazon Aurora, Amazon RDS, Amazon Redshift, Google Firebase, and CSV files.

Step 1. Download and Install the Open Automation Software and Start the OAS Service

If you have not already done so, you will need to download and install the OAS platform.  Fully functional trial versions of the software are available for Windows, Windows IoT Core, Linux, Raspberry Pi and Docker on our downloads page.

On Windows run the downloaded Setup.exe file to install one or more of the Open Automation Software features. Select the default Typical installation if you are not sure what features to use or the Custom installation if you want to save disk space on the target system.  When prompted agree to the End User License Agreement to continue the installation.

The OAS Service Control application will appear when the installation finishes on Windows.  Use this application to start the 3 Services. Run the Configure OAS application on Windows and select Configure-Tags; if the first time running, the AdminCreate utility will run to create an Administrator login as shown in Step 1 of Getting Started – Security.

Step 2. Configure Your OPC UA Data Source

  1. First, you will need to open the Configure OAS application from the program group Open Automation Software.

  2. Select Configure >> License from the top menu and verify that OPC UA is one of the available Drivers in the lower left of the form. The demo license will have this by default. If you do not see OPC UA available, contact support@openautomationsoftware.com to update your license.

  3. Select Configure >> Drivers from the top menu.


  4. Select localhost or the remote service you wish to modify with the Select button to the right of the Network Node list.


  5. The Configure Drivers Screen will appear. Select Siemens from the Driver dropdown box.


  6. Enter a meaningful Driver Interface Name that you will refer to this physical connection when defining Tags with a OPC UA Data Source.

  7. Define the properties for the desired physical connection.

  8. Click the Add Driver button above the Driver list in the left pane to add the Driver Interface as an available selection when defining Tags in the next step.

Step 3. Configure Your Tags

OAS provides multiple ways to add and define tags:

To add a Tag manually:

  1. In the OAS Configure Application, select Configure >> Tags from the top menu.


  2. Select localhost or the remote service you wish to modify with the Select button to the right of the Network Node list.


  3. Click on the Add Tag button located at the top of the Tag browser on the left portion of the screen.


  4. A dialog box will appear. Enter a name for your new tag and click ok.

  5. A configuration screen will appear for your new tag. Select your data source type in in the Data Source dropdown box.


  6. Specify the correct data type in the Data Type dropdown box.

  7. Click Apply Changes at the bottom right of the window.

Step 4. Configure Data Logging

  1. In the OAS Configure Application, select Configure >> Data Logging from the top menu.


  2. Select localhost or the remote service you wish to log data from with the Select button to the right of the Network Node list.


  3. A Logging Group screen will appear.


  4. In the Common Tab, you will determine your table format and type of logging you wish to implement.

  5. In the Tags Tab, you will select the tags you wish to log.

  6. In the Database Tab, you will select what type of database you will be logging to and enter the connection parameters. OAS can log to SQL Server, Oracle, Access, PostgreSQL, Cassandra, MongoDB, MariaDB, SQLite, InfluxDB, and MySQL.

  7. If you wish to log to CSV, you would configure that in the CVS Logging tab.
