# Dataforum acron

A JUNE5 acron data source represents an acron system. Each acron system is assigned to a JUNE5 acron data source. Multiple JUNE5 acron data sources are grouped into a JUNE5 acron data source endpoint.

To establish a connection to an acron system, the JUNE5-ACRON-Service must be running. Access to the acron database permanently occupies an acron client license in acron. A network license for acron is recommended.

{% hint style="info" %}
For JUNE5 to securely access acron, starting with acron version 9.3, a ***License Consumer*** must be permanently assigned for the computer running acron. This assignment is done via the ***acron Admin*** module. For this, the Fully Qualified Domain Name (FQDN) of the computer must be entered in the table under the ***License Options*** menu item.
{% endhint %}

If multiple acron versions are running on a single computer, the installation path for each version must be specified in the data sources.

{% hint style="info" %}
A maximum of two different acron versions are supported. For example, acron 10.0 and 9.3.
{% endhint %}

## Supported acron Client Functionalities

* Synchronize with the acron system model
* Retrieve measurement values for process variables of type Auto, Manual, Calculation, and external process variables
* Retrieve reports
* Retrieve events (steps are not supported)
* Retrieve alarms

A JUNE5 license (Basic, Professional, or Enterprise) is required.
