Write to text file
Hi diablo,
many problems:
1) In the moment you are writing the same text again and again into the file until you press the stop button...
2) As there is no wait statement in the loop you write as fast as possible - you're a cpu hogger!
3) As you don't use 'Set file position' you overwrite the file in every iteration!
4) As you don't use a shift register for the error cluster you will run into an error with every iteration again (if an error occurs)!
Look at the context help for the 'Write to text file' function - this will help you a lot!
This is a sketch of what to do:

Hi diablo,
point 4 is not correct - your loop will stop on an error - sorry. But I still prefer shift registers for error clusters!

Frankly, I have no idea why you are even using a while loop. Just save it once and be done with it.
I also have problems understanding your question. What is it that you want to save, "program's instrument" can mean anything. Do you want to save configuration settings? data?
"Doesn't work" also does not mean much without further details. Does it crash, generate an error (what is the error code), give incorrect results, etc.?
So, please be a bit more specific. It can also help if you attach the real program. 🙂
Hi,
yes, the loop isn't needed when you want to save just on answer.
When you want to save more than one answer of your device to the same file you will need the loop. But the it would be better to include to device communication in the loop - the string control in my example is just a representation for any kind of data source...
