DIO Config problem

[CF_eee]

Hi,

Using a 6533, I am trying to output data to two different FIFOs through the two 16-bit ports on the DAQ card. In Labview I set up two separate DIO config, write, run, etc. sets to do this task. When I try to run I get an 10403 error for the DIO config that this action is unappropriate. I gave the two DIO config different group numbers (although they are arbitrary numbers since I don't know what it means) and I have already established that my #scans/updates is correct. The only difference between the two DIO configs are the port lists. Can I even use two DIO configs at the same time? I don't see any problems when I use only one DIO config when I'm working with a single port. Any insight will help.

Hi CF_eee,

How exactly did you set this up, and what ports are you writing to? It sounds like you are possibly specifying the ports incorrectly. If you look at the LabVIEW Help on DIO Config, you'll see that only certain port configurations are available for the 653X cards. You may also want to check out this post:

You can use 2 DIO Configs at the same time, the Write to 2 Ports (653x) shipping example uses 2 DIO Port configs, which you may want to try as a starting point.

Hope this helps,
