Cluster update

[Randall Miller]

I have a tabbed multipage display where eace page is a cluster. Only one is
visible at a time. One of these clusters contains 60+ tag values. I want each
tag read vi to be in a separate loop and update when changed. If each loop
contains a read local, update cluster fields, and write local, new data is over
written by another loop's update. I can just read all the tags, but this is a
waste of CPU time. I have tried making local copies of the tags, then
assembling a new cluster, but this is faster, but still is a waste of
resources.
