error 1073807246 cRRIO 9074 migrated to cRIO 9030

Solved!
Go to solution

Hello again,

 

In a current LV 2015 project in hybrid mode I replaced a cRIO 9074 with a 9030. Its all running fine, RT main vi launches all the subvis for instrument communication. But then the subvis don't go past initialisation. It seems the visa ports are blocked by another application. When closing the RT Main vi, I get an error code 1073807246. Plus in MAX, if I want to open the port in question with open in visa test panel, it says, port is in use already.

Error opening resource:

visa://10.4.4.133/ASRL6::INSTR
VISA:  (Hex 0xBFFF00A7) The remote machine does not exist or is not accepting any connections. If the NI-VISA server is installed and running on the remote machine, it might have an incompatible version or might be listening on a different machine

I tried this already:

visa server is all the same, its a clean install of LV2015 SP1

ports are all there. What I did, open existing project, discover cRIO in Scan mode, then added FPGA. Then dragged everything underneath the new chassis and modules, just in the same order as it used to be. Then deleted old cRIO. FPGA compile wend tine and upload, and it launches everything.

the cRIO 9704 chassis has 1 serial port. cRIO 9030 chassis has 2 serial port. This means I have to ass 1 to all my addresses. I.e. ASRL 4 is now ASRL 5. Then it works
