I had previously written a VI which acquired data through both MODBUS and a cDAQ. I was new to labview at the time, and used the Express VI to setup the data acquisition.
I am currently trying to re-write the analog acquisition portion of the vi using more traiditonal DAQmx functions. The reason for this is that I happen to change sensor types regularly (mostly flipping between K and J type thermocouples, 3 and 4 wire RTD's etc). Thus I wanted to change the acquisition so that I could configure those inputs during run in the main vi.
I realize that you can't change configuration during acquisition, but I want other parts of the main vi to remain active while I make changes.
Thus, I wrote the attached vis as a test. I wrote one VI (Analog Acquisition) which will configure all inputs. I then want to take that configuration and run the task in another loop. The catch is that during acquisition I want to run continous samples. For the life of me I can not figure out how to do so. Test Program2 is the main.

Well,
I figured it out. When all were placed in a state machine, life got a lot simpler. Back to the basics.
