As Peter mentioned below, this would tell us if the 325K error is caused by the LV Chassis or some conversion done in LabVIEW. <br><br>Since we cannot force the 325K error, we will have to wait for the error to occur to compare the raw LV Chassis output. <br><br>Best regards, <br>Tyler <br><br><br><br>From: "Amrit Yegneswaran" <yeg@jlab.org> <br>To: "dsg-hallb magnets" <dsg-hallb_magnets@jlab.org> <br>Sent: Thursday, February 9, 2017 2:44:31 PM <br>Subject: Re: [Dsg-hallb_magnets] cernox sensors <br><br>thanks peter and tyler. <br><br><br>From: "Peter Bonneau" <bonneau@jlab.org> <br>To: "Amrit Yegneswaran" <yeg@jlab.org> <br>Sent: Thursday, February 9, 2017 2:16:49 PM <br>Subject: cernox sensors <br><br>Hi Amrit, <br><br>I looked at the LV cRio code with Tyler. <br><br>They don't seem to know if the excitation chassis is the problem or the <br>conversions, etc in the code. <br><br>The data is sent to cRio as text via serial communications then <br>immediately changed to a number for the calculations & lookup table. <br><br>We've seen a lot of errors in serial communications in other <br>instrumentation. <br><br>I suggested to Tyler that we latch the received text numbers V1 and V2 <br>when this error occurs before the conversion to numbers. <br><br>That will tell us if the excitation chassis is not sending or we're not <br>receiving the raw data correctly. <br><br>Thanks, <br><br>Peter <br><br>_______________________________________________ <br>Dsg-hallb_magnets mailing list <br>Dsg-hallb_magnets@jlab.org <br>https://mailman.jlab.org/mailman/listinfo/dsg-hallb_magnets <br><br>_______________________________________________ <br>Dsg-hallb_magnets mailing list <br>Dsg-hallb_magnets@jlab.org <br>https://mailman.jlab.org/mailman/listinfo/dsg-hallb_magnets<br></div></div></body></html>
