faster logging rate RS232

[DSRTM]

Hi Guys,

I'm looking for some assistance in how to increase the logging rate of the data coming from my mass flow controller via RS232.

Can someone direct me to a tutorial on how to get more data saved per second in my "write to text" file within a while loop?

thanks

The conversion to text is a big slowdown, and also writing small texts is slower than making a bigger set and write that in a parallel loop.

I also tried "write to measurement file" vi with exactly the same result. I don't thijnk it's the text writing part, but I'm not really sure how to say exactly since I need to log to a file to see what the logging rate

Do you have an example of making a bigger text set and writing that in a parallel loop?  Are you referring to a second while loop?

Thanks

Darren

Look at the producer consumer pattern example.

And with text I mean the conversion from binary (dbl or int) to ascii. But probably the size of the block does matter more.

Simply concatenate the strings before you write them to file. A block of about 4k is a good starting point.
