Hi, i am new to Labview and am trying to develop a vi to monitor ambient conditions from an instrument, Basically Temperature, Humidity, Barometric & Dew Point. I have the vi communicating with the instrument over RS232 the vi reads the values from a string every second and converts them to a number to be read in an indicator and chart but i also need to log this data to a file every 15 seconds. Do i convert the numbers back to a string and then write to a file or would it be best to log the data at the beginning and write straight to a file?? I have attached the vi and although not very pretty at the moment (this is my first vi) it works but i need to get the data into a file for record retention? Any help would be most appreciated?
