reciving data from RS232

[rsw]

Hi,

In the VI's you attached there are 2 key stages you need to look at, firstly outside the while look where the file is either created or replaced. I would recommend using this VI within your application as there is no point re-inventing something that seems fit for purpose. The second area of interest is with the  "Format into File" function, again in the top level VI called "Temperature Logger". This basically takes the current date/time, followed by a tab then the data you wish to store (in this case temperature but could be anything from the serial port) followed by an end of line constant to ensure the program stores the data on seperate lines.

These are the areas I would recommend you focus on for your application,

Hope this helps,

All the best,

The program you posted is obviously not the one you are using now since that logs every 500 msec and only logs temperature. If your current program is similar, change the value you pass to the wait and wire up a format string to the Format Into File. You can simply right click on it and select 'Edit Format String'. The on-line help has quite a bit of information on format strings.

If you don't want to log all of the data, just place your file write function inside a case statement and use an Elapsed Time function. There is a Boolean output of that called Time Has Elapsed. Wire that to the case statement.

If you have the professional version of LabVIEW or the separate app builder, you can create an exe. Otherwise, you can password protect the block diagram.
