Update only new digital state sets

You can change the default behavior that automatically updates archived digital state sets, by using the DigitalSet point attribute. This attribute specifies the name of the digital state associated with the point.

If you want only new values received by the archive to use the updated digital state, you can add a new state set and change the DigitalSet point attribute to use this new state set. For example, you can create a new state set named Old Valve Position and configure events of 0 that were recorded before you change the DigitalSet point attribute to use the CLOSED digital state. Then, you can configure Valve Position to use SHUT for events of 0 recorded after the point attribute edit.
