I am operating over a VPN. When retrieving the snapshot value for a very large number of tags using the or using DataLink, it takes a very long time.  However, retrieving the current value using PISMT, the time required is much much less (maybe as little as 10% of the time). What method does PISMT use to retrieve the current value? Given a Pointlist object, what is the most efficient way to retrieve the current value for each point in the Pointlist? thanks. don
