# DDE - Dynamic Data Exchange

Measurement data can be transferred via the standard Windows DDE interface from a DDE Server (control system, PLC driver, ...). Alert data for malfunction and message processing by ACRON cannot be imported.

ACRON provides four different DDE interfaces:

* [Cyclic DDE](/acron-9.3/en/anlagenkonfiguration/prozessanbindung/provider/providerid/treiberauswahl/dde_dynamic-data-exchange/dde_zyklisch.md) (DDECyc.drv)
* [Event-controlled DDE](/acron-9.3/en/anlagenkonfiguration/prozessanbindung/provider/providerid/treiberauswahl/dde_dynamic-data-exchange/dde_ereignisgesteuert_f_pcvue-coros-lsb-procon-win-excel.md) (DDEEvent.drv)
* [FAST](/acron-9.3/en/anlagenkonfiguration/prozessanbindung/provider/providerid/treiberauswahl/dde_dynamic-data-exchange/dde_fast-f-intouch_inat-h1.md)[-DDE](/acron-9.3/en/anlagenkonfiguration/prozessanbindung/provider/providerid/treiberauswahl/dde_dynamic-data-exchange/dde_fast-f-intouch_inat-h1.md) from Wonderware (DDEFast.drv)
* [DDE Advance](/acron-9.3/en/anlagenkonfiguration/prozessanbindung/provider/providerid/treiberauswahl/dde_dynamic-data-exchange/dde_advance_f_rsview.md) from Rockwell (DDEAdv.drv)

Note

If the DDE server/control system supports more than these DDE interfaces, the DDE interface types should be selected according to the following priority:

1. [DDE Advance](/acron-9.3/en/anlagenkonfiguration/prozessanbindung/provider/providerid/treiberauswahl/dde_dynamic-data-exchange/dde_advance_f_rsview.md)
2. [FAST-DDE](/acron-9.3/en/anlagenkonfiguration/prozessanbindung/provider/providerid/treiberauswahl/dde_dynamic-data-exchange/dde_fast-f-intouch_inat-h1.md)
3. [Event-controlled DDE](/acron-9.3/en/anlagenkonfiguration/prozessanbindung/provider/providerid/treiberauswahl/dde_dynamic-data-exchange/dde_ereignisgesteuert_f_pcvue-coros-lsb-procon-win-excel.md)
4. [Cyclic DDE](/acron-9.3/en/anlagenkonfiguration/prozessanbindung/provider/providerid/treiberauswahl/dde_dynamic-data-exchange/dde_zyklisch.md)
