# Async Data

Async data is used when acyclic data such as tightening results need to be sent over the process data.

If the signals Fieldbus AsyncData to PF and Fieldbus AsyncData from PF are added to a fieldbus map and then mapped to a virtual station, AsyncData is enabled and if an acyclic result configuration is mapped to the same virtual station, then the result is output to AsyncData and not to acyclic data.
