I am attempting to read a 2-column text file of tab delimited values. The values represent the time and setpoint array to be sent to the Labview PID_setpoint_profile.vi. The text file needs to be converted to values and then into a cluster which can be read by the PID_setpoint_profile.vi. My problem is generating the cluster of 1-D of 2 elements to send to the vi. I included a modified version of the Read Strings from Spreadsheet File.vi. I would appreciate any help.Thanks.-dewey
