How to control tank and thermometer in my virtual system

[kolacja]

Hi all

I have a problem with my program in labview. I'm trying to create an app that consist of 4 parts:
1. To fill first tank from 0 to 90 (first variable - water level )
2. To raise temperature form 0 to 40 (second variable - temperature)
3. To move water from first tank to the second 
4. Back to first point - filling the first tank
etc
I've used 2 switches: turn on/off, start/stop process. Both of buttons can stop the whole process but values of all variables should be remembered

Thanks,

Tom

Hi Tom,

Thank you for describing your application. Looking at your project, it seems obvious what you can do to improve your application.

The architecture you chose resembles that of a finite state machine.

In order to properly implement it, please use Enumerated constants instead of String constants for your states.

To preserve and correctly control dataflow, use shift registers on your while loop instead of variables.

To get started quickly with your architecture, select Create New - VI from template from the File menu in your project window. In Frameworks - Design Patterns choose Standard State Machine.

To fully understand dataflow in LabVIEW, go through tutorials and learning materials here
