FPGA Up Cast Funktion deletes Values form Read/Write Controll

Hello Everybody,

 

I Have an other Problem with my RT-FPGA cRIO...

 

I have now managed to read the module IDs to convert this combination in a certain casenumber and this one then selects the FPGA File. Now is that I have inbounded various FPGA Bitfiles. If I composed them by the the "Up Cast function" to a universal reference then there will disappear some elements by using the Read / Write Control .

I have a picture attached that this Clarifies!

The first two R / W Controller have been up before the cast and the third upcast diverted after.

I hope you can help me!

thank you in advance before

Even now I've noticed the function Invoce methode: Read TEDS is also no longer supported.

Why?!

The both VIs are exactly the same during the Modules in it are different.

Iam using LabVIEW 2009 and the newest Drivers from the NI site!

Hello MaJahn,

 

there are a couple of restrictions to using the upcast function:

 

  1. The FPGA target must be of the same class. For example it is not possible to use a reference made from an FPGA VI built targeting a PCI-78xx to also communicate with a PXI-78xx
  2. The controls and indicators on the FPGA VI must have the same name and tab order.
  3. DMA FIFOs are not supported using the Up Cast
  4. The target must support this functionality.

Please check that all of these points are fulfilled for it to work.

 

Regards,
