MAX 4.0 loses visa tcpip resources after closing

[Gerardo09]

I am using max to configure some tcpip resources.  I am able to connect to them through the MAX (verison 4.0) through the test panel. However, they are not working in labview (version 8.0) using the visa open. When I open the MAX again, there is an error and it states that it could not connect to the resource, but I can still open up the test panel and write and read. 

Thank you,

Gerardo

Hey Gerardo,

When you open a test panel to the device in MAX, do you close it before trying to call the VISA Open function? Also, in LabVIEW, do you call a VISA Close function at the termination of your program? With VISA functions, you need to bookend your functions with a VISA Open and a VISA Close so that the resource is freed after you're done using it.

What is the error code/message that you are receiving?

Justin,

Yes, after I would open the test panel, I would close it and then I would try to write to the device.  And yes, I opened and closed the VISA resource.  I actually had it working perfectly fine on another computer, but then I swapped computers and this started to happen.  I tried several things but finally just uninstalled LabVIEW completely and then reinstalled it.  It now works perfectly fine. Thank you for you help anyways.

Gerardo,

Glad to hear you're program is working
