TestStand/LV VISA error

Hello Support,

 

I am encountering a VISA error while trying to Initialize a COM port using a LV-VI from Teststand. I have (3) GPIB devcies that Init properly, from the same VI. See attachments.

I am able to Init the COM port, after going into MAX and verifying VISA alias name, no actions made within MAX.

However, the problem comes back when I shutdown the system.

Hello DAY-TE,

 

Looking at the VISA Init COM Port error wiring diagram it looks like you are initializing the port and then using VISA Open afterwards. The Initialize VI for your device should already be handling opening the resource. Check the documentation for the reset VI because resetting the device might not necessarily close the the resource so using the VISA Open would be redundant and therefore cause an error.
