execution sequence

[Cool : ASDF]

Hi all,

I have three case structure.

I want to define the execution sequence as shown in the following ex .

Please help its urgent

Hi Cool : ASDF,

you can do it with a state machine. You need only one case structure for it. Create a case for each of your actions.

Thanks for quick reply

I dont know basics about state machine, can u provide one example how to implement my code.

actually i dont have that much time to understand about the state machine,

as i have to provide it to customer.

thanks

Hi,

is it your homework for tomorrow?

For more information on this, see the example finder.

Cool,

Just type in 'State Machines' in NI's website search bar, there must be hundreds of examples already available. If you dont have time to learn about a state machine then your 'customer' should get his 3 execution software written elsewhere.

You should start with this KB article: Application Design Patterns: State Machines.

The quick and dirty solution is to put them in a sequence structure to force execution order.

Implementing your sequential state machine now will save you time in the future, so I would suggest doing it now also if you look at the VI from template at the start screen for labview you can go down to Standard State Machine and it will give you a basic state machine to start with

I'm surprised to see this suggestion but please do not follow this advice. LabVIEW is a dataflow language, not a traditional sequencial language. If you follow this advice you will not be able to harness the full power of dataflow programming. Please take some time to learn the basic concepts of dataflow programming. State machines are very easy to implement in LabVIEW and they are a fantastic programming model. As suggested by Harold earlier in this thread take the time to learnhow to use them. It will pay off many fold in the future.
