fpga IO module clock with TRIG

[NicolasQ]

Hi,

I'm working with the "IO module clock 0" at 100MHz. My problem is when I'm compiling, I get Error Place905. I found out that it's because I'm using a PXI trigger inside the timed loop. Is there a solution to use triggers with this clock? 

I joined the error log and the VI.

I must use that clock.

I'm programming 16 NI PXIE-7962R FLEXRIO FPGA in a PXIE-1075 EXPRESS CHASSIS.

Thank you

Hello,

What version of LabVIEW are you using? Are you using a FlexRIO adapter module? What version of the Xilinx tools do you have installed?

I found a KnowledgeBase article that explains in depth why you may be seeing the "Compilation failed due to a Xilinx error" Error. You may just need to download the patch if your setup meets ALL of the criteria listed in the KB.  I have attached a link to it here.

Error, "Compilation failed due to a Xilinx error," When Using NI FlexRIO or NI CompactRIO

Please post back if you are still having issues.

Hello,

I've got a little more information for you.

PXI_Triggers can only be used in global clock domains and not regional clock domains. With the older 5781 CLIP, the IOModuleClock0/IOModuleClock1 were regional clock domains. However, with the newer 5781 Synchronous CLIP, IOModuleClock0 should be a global clock and you should be able to use PXI Trigger.

You should upgrade to the newest version of FlexRIO Adatper Module support and use the newest 5781 CLIP.

You can access the upgrade here:

Thanks a lot Jordan, I'll try the upgrade and will let you know if we have any problem left...

Thanks Jordan for the update,

In fact, we can now use the IOModuleClock0/IOModuleClock1 with PXI triggers and timed loop but we still have compilation errors when using IOModuleClock0/IOModuleClock0... not a real problem now but here is a screenshot of the compiation problem..

If yu have any clue...

Thanks a lot and have a nice day !!
