Just like to thank you NetDevil for writing this macro. I've used it successfully for a year or so with a sketch to measure the Ah capacity of lead-acid batteries with an arduino. Should have thanked you earlier. I found macros quite tricky to write so karma to you.
Hi ianthetraveller,
thank you very much for feedback 
I really enjoy getting to know the projects people are doing with PLX DAQ. This is what inspires me the most with Arduino, everyone can become a creator. Good luck with your project!

Hey NetDevil, Thanks a lot for the updates. I am trying to add more sensor values into different columns but am unable to do that. Do you have any suggestions for that.
Hi Vik,
you can easily add multiple values in your DATA command like this: Serial.println( (String) "DATA,date,time," + value1 + "," + value2 + "," + value3); There are multiple examples of it within this thread as well as in the BeginnersGuide I guess. Have fun
