POLabVIEW: Extract data after a certain line

copied!<p>Any advice or help would be much appreciated.</p> <p><strong>Question</strong>: How to extract data after a certain line from a comma deliminated strings which are read from a serial port ?</p> <p><em>More Info:</em> A have a card that is gathering data values and is read into the computer via a serial port. Example string of data acquired as below:</p> <pre><code>;Data = 1 bps Tool = Sensor ;Label, Time, Voltage, Pressure, Temperature, Current A, 01:33, 5.1, 18.1, 31.2, -, B, 01:34, 5.5, 19.2, 30.5, -, ;Data = 1 bps Tool = Sensor ;Label, Time, Voltage, Pressure, Temperature, Current A, 01:35, 5.3, 18.3, 30.1, -, B, 01:36, 5.1, 19.0, 30.5, -, ;Data = 1 bps Tool = Sensor ;Label, Time, Voltage, Pressure, Temperature, Current A, 01:37, 5.1, 18.1, 30.8, -, B, 01:38, 5.3, 19.2, 30.1, -, </code></pre> <p>These data value will be kept updating line by line. I would like to start extracting the data only on the 3rd block of incoming data. I would not want the first 2 blocks of incoming data.</p> <p><em>Further Info:</em> Currently, my idea of doing that is to scan the ";Data" and put it into a counter. If there are 2 ";Data" scan, then from the counter it woud output a True value to a case structure to start extracting the data. Please see my attached photo.</p> <p>However, I am not able to create such a counter using an array as I cannot use a while loop and shift register. Do you have any idea how to start extracting data from 3rd block onwards ? Thank you very much.</p> <p><img src="https://i.stack.imgur.com/Yu0Iw.jpg" alt="enter image description here"> </p>
