VISA read timeout error

$

Hello, I am very new to LabVIEW and not really used to working with electronics so please bear with me.

 

I am doing a VI for controlling an installation that has some mass flow controllers and some pressure controllers. The connection of this controllers with the computer is done using an ADAM-4000 series device (bellow you can find the manual for this device).

I am doing this VI using as model a previous one that was done some years ago for a similar installation (this VI isn't bellow because it has more than 10 MB, however bellow there is some prints of this VI).

My first problem was that I was using the Property node: Bytes at port and the number of bytes that was obtaining was 0. After some reading in this forum I decided to not use it and change it. Now the problem is that after the information reaches the VISA read I get this error: -1073807339 (0xbfff0015) Timeout Expired Before Operation Complete. I tried increasing the timeout period but it didn't work.

 

Can anyone help with this?
