Hello,
I have to adapt older code for re-use and I have a general question about this.
There is a main VI with sub-VI. Main-VI does GUI and so on, Sub-VI does data acquisition (connect to chassis (9184), read input, calculate stuff, close connection to chassis on program exit). Now, I need to add an analogue output card.
Problem is: only my Main-VI has the information, that needs to be output on the analogue output device. How can I accomplish this, if all the communication with the chassis is done within my Sub-VI? Do I use a channel between Main-VI and Sub-VI?
Thank you for your advice.
Martin
