I am a quite new to LABVIEW. I have a one.vi which consists of several subvi's. These subvi's have the input and output , set up from creating control variables (named like VISA session (input) and DUP Visa Session (output) ) . After I see that these subvi run correctly, I open the vi file, but it does not reflect every terminals of subvi.
Especially, the inputs and outputs of subvi are not shown in the vi file.
Do I need to set up these variables as input and output?
thank you in advance,
