I've written a VI that cycles solenoids for different time duration, and due to our data logging software, we can't interface with LabVIEW to log our data. In order to know when each valve cycles I've set up a method to write to a text file with the date/time the solenoid switched. I would like to write to the same file for each section of the code. The way I've set it up works fine, but I'm thinking it's not the best way to do it. I've attached a screen shot of what I have. I was thinking of making the control a type-def or reference, but it doesn't work that way.
The sequence shifts from one sample to the next with a purge in between. I didn't use a reference wire because I don't know what that is (I'm still new to LabVIEW). The Close File doesn't seem to effect the outcome. I've attached the VI so you can see what I'm going after.
