Overview
In FrameworX, it It is possible to establish a robust and secure connection with a PostgreSQL database using the TagHistorian Tag Historian feature. The steps to achieve this involve renaming databases, creating and testing the PostgreSQL connection, configuring tags and tasks, and writing specific queries for select, insert, update, and delete operations.

Configuration PostgreSQL via TagHistorianTag Historian
In this example, we present the configuration of Postgre using TagHistorian.
First, you can access 'Datasets > DBs' and need to rename the SQLite database "TagHistorian" to "TagHistorian2" or another name.
?
Now you can access 'Datasets > DBs', select the PostgreSQL Data Provider option and click on 'New item...' and create the Postgre with the name TagHistorian.
In the ConnectionString column, you can configure the Server parameter with the IP of the Postgre Server, the Port, and the name of the Database configured on the Postgre server.
Don't forget to configure the LogonName and LogonPassword column.
| Note |
|---|
Note: to modify the password column, you need to switch to Administrator. |
Click Test and check the connection with the Postgre Server.
In 'Datasets > Queries', some queries were created as shown in the image below. We use Select, Insert, Delete, and Update in this example.
Now, in 'Unified Namespace > Tags', it is possible to create some Tags to use in this example. The Integer01, Integer02, and Integer03 are Tags that we will use to send values to the Postgre DB.
The "TriggerUpdate", "TriggerSelect", "TriggerInsert" and "TriggerDelete" are used to trigger some task scripts that we will create in the next steps.
The tag "QuerySelect" is used to receive the result of the Select query.
In 'Historian > Historian Tags', it is necessary to configure Integer01, Integer02, and Integer03 Tag, Table1 is standard and is configured to use PostgreSQL.
Now, in 'Scripts > Tasks' you can create some tasks to Select, Delete, Update, Insert, and configure the Trigger column with marks created before.
The scripts are:
Select Query:
Insert query:
Update Query:
Delete query:
We can run the project and give some different values to the Tags. thus, within pgAdmin 4 we can see that Table 1 was created with values that were given.
Thus, we trigger tasks through Trigger Tags, all Queries were successfully performed.
Our Table within Postgre is updated with the Queries we created before.
