The Timestamp from my FieldPoint Read VI only Updates when Data Changes

Primary Software: Driver Software>>NI-FieldPoint

Secondary Software: LabVIEW Development Systems>>Base Package

Problem:
I am acquiring data from a Compact FieldPoint module using the FieldPoint Read VI.  The Timestamp only appears to update when data changes.  How do I get a timestamp that reflects the time when I read data from the module?

Solution:
This is expected behavior.  For example, consider the data below.  Either the loop rate was faster than the update rate of the module, or the data on the channel was not changing.  When either case is true, the Timestamp data is constant between reads.

In order to obtain an updated timestamp with each FieldPoint Read, you should use a Flat Sequence structure.  In the same frame as the FieldPoint Read, use a Get Date/Time In Seconds node.

The program obtains a fresh Timestamp each time the FieldPoint Read VI is called.
