Hi,

I have to communicate in modbus with a machine which is in ASCII, so I want to create a drop-down menu within all the ASCII command. 

Any Idea ?

thanks

You can take all the commands into Ring control and pass the values using the property nodes.

Hi Peter,

"Any Idea ?"

Yes: take a dropdown menu (aka Ring) and input all your "ASCII command"...

What answer do you expect? Just create the menu!

[Peter Saraiva]

I don't really know,

In fact, in the drop down menu I want to put the instruction (example : Move to the first position) and when this case is chosen we send the ASCII code of this instruction to the machine..

[P@Anand]

If that is a big instruction then you can go for Enum so what ever you want the desciption of the command put it into Enum so correspondingly in case structure you can send the command.

Hi Peter,

"when this case is chosen we send the ASCII code"

Well, that sounds like the perfect use for a case structure, don't you think?

[Peter Saraiva]

Yes of course I'll use a case structure.

but in what kind of variable should I put my string command ? and where can I find that ? knowing that the command are in ASCII

Regards

Hi Peter,

- LabVIEW doesn't work with variables...

- when you need "ASCII commands" I would use a string constant...

Ok, sorry I'm a new user of labview lol  

Thank you for your help;

Actually-  This sounds like a great use for a combo box.  They are a littel under used but can very easilly map a pairs of strings.  Display "Human readable" and value in ASCII.
