Currently I have two channels being transfered into the AI C-Scan block (by means of a build array) in hopes to display the outputs on a chart as well as an output file. As an outout I am using the waveform data type, as I hear this is the way to go. Problem is that I have the the Waveform chart directly connected to the waveform out put the the AI C-SCAN block but nothing is being displayed on the chart. Although the time is updated on the chart it is listed as the year 1903. I do have data these channels as the there are digital outputs for these channels. Perhaps I should use the AI CONFIG and AI READ clocks rather than this AI C-SCAN. Any ideas...
