Need help separating/timing data written to file. Simple vi

[cramezl]

Hello all,

I made several posts last week seeking help with my simple pressure transducer vi. Though I got some great advice, I found a simpler way to construct it, so I started from scratch today. I'm much happier with the new vi, but I still have a couple issues I need help with.

1) I am writing the date, time, and pressure to a file. How do I separate the data into three columns? column 1- date, column 2- press, etc.

2) I only want to write to the file once a minute on the minute mark. I was told to wire the "i" terminal of the while loop to the case structure, dividing by 60 and only recording when the remainder=0. But, it doesn't seem to be working.

Attached is the vi I'm working with. Any help is MUCH appreciated.

i would use a tic count function, your 60 is happening every 3 secs...

your vi is using build array for you string, use concatenate with comma's between your data to make columns...

your VI perplexed me...I did have the same problem before, but solve it with a not so "absolute" value. i made a work around for you to play with using tic count and don't forget to use "wait (ms)" in your loop, otherwise it will use 100% of your CPU.... 

notice that i did not use "concatenate" with commas, you can also use "format into file" with formatted constant.
