SCRAMNet, LVRT driver and VISA layer

[Former NI Employee MS]

Update

LabVIEW RT 8.6, VISA 4.4 - ony SCRAMNet code (no additionnal HW)

=> many RT target random crashes (interaction with additionnal HW doesn't seem to be the source of the problem)

LabVIEW RT 8.0, VISA 3.6 - only SCRAMNet code (no additionnal HW)

=> no RT target crash

LabVIEW RT 8.0, VISA 3.6 - SCRAMNet + CAN code (no FPGA since we had no compatible NI-RIO layer)

=> no RT target crash

Next step is to go back to 8.6 with same code and see if we experience crashes again

Got a headache  now

Update

Here is  a working configuration... Took a long time to get there

No more RT target crashes, and we are able to share data between the two computer.

Next step is to upgrade step by step and see if it work...

Update:

Upgrading VISA tests have been tried but unsuccessfull due to the project context.

So that we are not able to have any other configuration that would work. I confirm that the previously listed one works fine.

These tests might be done later.

Ben, thanks for you answer (and kudos as well).

Has anyone had any success with GT cards and labview 8.6?  I have gotten two SCRAMNet GT cards to communicate with eachother using RT 8.6.1 and VISA 4.4 without crashing, but im having .dll errors when deploying described here:

We have not tried it in 8.6 but I remeber the developer saying he was having issue with deploying the dll..... Did he resort to using FTP to put it there...?

He is teaching a LV course at the moment. I'lll see if he remembers anything that can help.

Yep he resorted to FTPing the dll because it just would not deploy correctly.

Suggestions:

1) Do the FTP yourself.

2) Contact Dale Cramer from Systran to see who his contact at Ni is and work with them.

3) Contact your local Ni rep and point them at this thread and explain what trouble you are seeing. They can get resourses to look at this issue.

When last I heard, NI was interested in making sure the SCRMANet was an option for LV so there is SOMEONE there who SHOULD care. The name I did have for inside NI "has left the building" taking all of his notes and knowlege with him.

Nothing to add (is there anything to add after Ben ?? 😉 )

Oh yes, just one thing: M1080, could you keep us updated please (if you have anything new) ?

This info will be of importance for one of my next projects.

Regards.

I got the system working, no errors or crashes yet.  Im sending and recieving interrupts and sharing several variables using PIO.  I had to FTP the following files to the system folder on the target to get my application to deploy correctly:

scgt.llb

scgtapi.dll

Word document is attached that shows my system configuration
