Hello,
I have a Test stand that tests 6 valves at a time. It tests a valve in -40 seconds. When a valve passes, I create a serial number that contains the hour, minute and fixture number that valve was tested on. If it is the first valve tested in that minute I append a 1 to SN, if it was second valve I append a 2. A csv file is created that contains test data for that file, the name of the file includes the serial number. to create the file I create a path with the serial number that ends in 1. I then check if the CSV file exists. If it does I change the SN to end in 2 and create a new file. This works great until I run all 6 fixtures at high speed. My VI consists of 6 identical timed loops. Each runs a clone of the "Save data routine". I end up not creating files ending in 2. With all 6 running running a file is being generated ~ every 6 seconds. My guess is that file is cached until it can be written to disk. I am wondering if I force the cache to clear and write to disk, if that will work, or am I exposing myself to other problems. The system is in China and I will be going out there in a few days to correct. Any help would be great. I am attaching sub vi that makes the file.
Thanks in advance.
