Serial Communication Failure with VISA Read

$

0

I am able to successfully communicate with the device, however, the output reads the default value everyother time. The VISA Read function reads the command everyother time instead of the value. When ran consecutively eventually the VI stops running and LabVIEW must be restart in order for the VI to communicate again. What is the cause of this? How can I fix it? Attached are two VI's that display this problem when ran. Thank you.
