I know this has been asked before but I do not get why I am receaving this code. The system ran fine for a while and then all of a sudden I get this code all the time. It worked before and I did not change anything that has to do with that scan part. I worked with the DAQ assistant a little and then I wanted to test if my work had any effect and then scan failure. I am lost. The string I am scaning is a position response that will be a #_# with the "_" meaning a space. I thought this is how I have it set up but maybe I have a error I cannot see. Also the # can be any real number. Thanks for the help and the vi is attached.
