Hi EduU,

here's an example based on my last message... I only made the general structure, you have to fill in missing parts

Attached a 7.1 example which writes to a file every 5 hours.

Hey Christian

Thanks for the example

but I'm having some problems here

I'm using the write [I16] file 

and when the time have passed, like 5 hours

the program close the file

and when will start the other one

i receive an error:

Error1 : Occurred at Write File +[I16]: Write file

Possible reason: An input parameter is invalid

I make equal yours, i will upload the VI so if you can

take a look and see what I'm doing wrong! =/

I put the value to compare as 10 only to make the test faster.

Thanks

You will need to change the loop tunnels of the file reference to shift registers.

Hey Christian, Now i have one problem when I'm trying to read the files I splited.

The first file, I can read it perfect, but the second and the others I receive the same error as I was receiving at write, but at Read File +[I16]

I tryed to change the loop tunel to shift register, but still don't work.

Any other clue to give me?

Thanks

Hi EduU,

how are you reading your files? How can there be an EOF error on start of reading?

Clue: Select the correct file for reading

Show your vi!

[EduU]

well I'm uploading the VI

and I'm selecting the correct file for reading

always when I execute this program I have to select which file will be read!

Thanks

Hi EduU,

apart from that horrible block diagram:

You only open one file and read from it continuously. I thought you had splitted your data into several files and now you read from one file only?

Please cleanup your VIs before posting...
