If we have network communication problem between PI Data Server and AF Server, what happened when communication will be restored?
In particular, an AF attribute (linked to a PI tag) takes just the value existing at the moment of communication restoring? Or it can recover all values archived on PI tag during the communication error?
This is important to us because we have a system which retrieves data from AF, and so we would like to know if with the communicatin problem we lose data or not.
Thank you in advance for your support,
