Question 21
You develop a SubVI that only outputs a value and need to use this SubVI in a (calling) VI. Which of the following is the best way to enforce dataflow to control the execution of the SubVI?
- Use the SubVI in a Sequence structure
- Modify the SubVI to have dummy inputs that can be used from the calling VI
- Modify the SubVI to have Error clusters that can be used from the calling VI
- Modify the SubVI to have a global variable and use it from the calling VI
