# Process connection

The process connection function is used to configure the import of external data into ACRON. A process connection is defined and executed by a [Provider](/acron-9.3/en/anlagenkonfiguration/prozessanbindung/provider.md) with the corresponding communications driver. The manual values are an exception in this. They are not delivered by a control system/PLC, but must be entered manually.

You can configure multiple Providers for one plant. This is necessary if you want to import data from multiple control systems, for example, as each Provider can only collect data from one interface.
