I couldn't find answer here, maybe it is too simple...


two GPIB 1 and 5

how to difine #1 using VISA source name at "Edit LabVIEW VI Call

Expand the control by clicking the + icon on the left.  You will see two fields.  One is the resource name, the other is the session number.  You will only need the resource name.  You will put the full address of the instrument here, like "GPIB0::5"

gunking,

Thank you for providing your sequence and VI. I am currently in the process of troubleshooting this and will respond as soon as possible.

[AllenP]

What does the error say?

Looking at the sequence file, you will need to put some value for the Session number.  Put 0 in, and it should work.  If not, please describe the error message.

[gunking]

yes, it works after the "0" put in.

thanks a lot. I was trying to use string instead of visa resource name control. but it didn't work yet..

hi, i had this problem too, but once i clicked on the + sign beside the "Visa Session" i could not edit the "Device Name" and the "Session Number". Please advice how can I edit the values.

Thank you.

ps. my resources are at GPIB0::5::INSTR

It sounds like you have a variable set for the VISA Resource Name already.  Make it blank and the other fields should become enabled.

Thank you! Its working now, top is the image of how it exactly works.
