    What is the OSIsoft best practice for digital PI tags whose data source's states have changed or swapped? Keep in mind; these PI tags have historized data that we want to keep. Thank you!


      Currently, we have some digital PI tags (ex. On/Off) whose data sources’ digital states have been swapped (ex. Off/On). My question is; how should we handle that change on the PI tags end as per best practice? Changing the PI tag’s digital set to (Off/On) in order to match the data source end may cause confusion to users who aren’t aware of the change.
