Action Engine DAQ Sample

[jyang72211]

Attached is a picture of a DAQMX example.  If I created an action action engine (AE) and put the first two nodes (create channel and start task) in the "initialize" action of the AE and save the reference in a function globel (FG), would I run the risk of losing the reference if I use the DAQMX Write Action later with the reference stored in the FG? I am afriend that LV is going to clearn up the reference when I am not using it.  

Do you foresee any problem with an action engine with this example?  First two nodes (initialize), 3rd node (write), and last node (close).  Thanks!

Shouldn't be any problem at all -- I do the same sort of thing all the time.  Just one little tip -- I wouldn't bother making a separate FG for the task refnum.  I would just put it on its own USR (uninitialized shift register) inside the action engine itself.

You meant the reference is saved inside the action engine, right?  That's my intention.  Thank you!
