Is it possible to receive data via RJ-45 like how data is received via RS-232?

I can understand the pressure you are under. LabVIEW is marketed (and rightly so) as a programming language that is easier to learn than the traditional text based languages. Easier is a relative term though and just like C++, VB, etc., there is a learning curve that can be pretty steep.

Keep plugging away and keep posting with your problems.

It's working now! after i change to read from spreadsheet, all the row are able to be sent line by line! but it stopped after it finish sending the text file, i wonder what did i do wrong LOL.

[Simmy]

could you please help me see what is the problem? my RS-232 will keep sending the files non stop, from the top to the bottom, then repeat itself, but this program doesn't, what could be the problem?

[Dennis_Knutson]

I think I gave you some bad advice about only reading the file once. For a simple fix, put the Read From Spreadsheet inside the while loop like the original RS-232 example.

i tried that, and got this error instead...

Hi Simmy,

you can use the "array to spreadsheet string" function. You only need to send your data once each interation.

i followed exactly like what you did, and it didn't work at all....

[MikeS81]

Hi Simmy,

and what exactly did not work?
See the attached example. It do the same, but without TCP/IP and it works like i expect it.

it will work when i do it this way(refer to attachment), but it still does not run the spreadsheet constantly, i need it to keep repeating the whole process over and over again... until i decide to stop this program...

Hi Simmy,

your picture shows not the same. Right click on your tunnel element on the loop and select "disable autoindexing".
