====IP21 Driver===

===Information===

The IP21 driver allows you to connect to **Aspentech IP21** systems to retrieve historical data.

We usually suggest using **OPC-UA** to connect to live data, as this provides the best performance while also having the smallest impact on your server.

//Note: Web access to IP21 servers consume **2** user licenses instead of the usual 1.//
