How do I ask Datalink to get the last known good values?

I have 619 tags that are I/O Timeout for current values.  This means that they had values at one time and I would like to know when that time was.  I was thinking that PI Datalink could could do this but so far I have not been successful in getting this data.  I can go into the Archive Data in SMT and get it, but  I have 619 Tags that I know of and expect more.
