How to extract the history data from Information Manager archives in bootable media
We have ABB 800xA DCS system installed. I have taken the time stamp values of a specific tag in an excel file. It is showing the values only for the period of one year, but I want to have the data for atleast two years. In our system, two Information Management IM Servers are present which create the archives of the historical data older than one year. We have these archives files present in bootable media (DVD). So how to access the data present in the archives file and thereby publish the timestamp values of a specific tag in an excel file for two years duration?
