- General VI
- State Machine VI
- Parallel Loop VI

What is one disadvantage of using the State Machine VI architecture?
- A State Machine can only traverse states in order.
- If two state changes occur at the same time, only the first state change will be handled and the second will be lost.
- The diagram becomes significantly larger when changing from a general architecture to a State Machine.
- State Machines cannot acquire data or use DAQ functions.
