Error - 1073807339 occurred at VISA Read

Hello, 

 

I am running an experiment using a potentiostat and a hotplate and a timeout error appears at random times. For instance, the programs will run properly sometimes but other times (most of the time) the error will appear within 15 min or 45 min and so on of the experiment. I'm not sure why. I have attached the VI's below.

 

The error for the hotplate always occurs at the second VISA read after the visa write of "FEA2 0000 00A2" and the error for the potentiostat occurs at the VISA Read after the VISA wirte of "READI"

 

Thank you for your time!
