Data logger

Overview

PROCON-CONNECT has an integrated data logger. This can be used to record process variables and save them in a database. The databases available are SQLite locally on the device or a connection to an InfluxDB.

Navigation

The overview of the data logger functions can be called up via the start page under Data logger (1). The ‘Open’ button (2) takes you to the ‘Data logger’ menu window.

Here you can choose between logger configuration (1) or data view.

Database connections

The overview of the database connections is structured as follows:

1. Existing connection with name is displayed.

2. The available data loggers appear when you expand the window.

3. Add a new data logger.

4. Add new connection (drop-down with selection).

An SQLite connection is only suitable for smaller amounts of data.

The ‘New connection’ button can be used to add a local SQLite database or to connect to an existing InfluxDB.

The local SQLite database is created on the device and is therefore suitable for smaller amounts of data. The configuration of a deletion interval helps to automatically minimise the data volume.

Connection to an external InfluxDB

1. Connection name: Must be unique, can be assigned individually.

2. URL: Computer name on which the database is to be added with port e.g. 192.168.1.164:8080.

3. Database: Name of the database (optional).

4. Organization: Subdivision of the database.

5. Bucket: Database

6. Storage rule:

7. API token: Access or authentication key.

Configuration of a data logger

1. General settings: Tab for definition of the logger.

2. Tags: Tab for selecting variables.

3. Connection name: Display of the connection name.

4. Logger name: Is assigned individually.

5. Sampling rate: Value of the read cycles.

6. Unit: Selection via drop-down in minutes/seconds/milliseconds.

7. Switch tag: Fills the track at “True”.

9. Has checksum: For FDA compliance testing.

The variables that are saved for this data logger can be selected in the “Tags” tab.

1. Filter: Enter search terms.

2. Name: Variable name

3. Type: Type of variable.
