error -200077 when deploying SysDef file

[pmac]

I added PXI-6704 as a DAQ device to my system definition file. When I try to deploy it I get:

"error -200077 The requested value is not a supported value for this property" 

The module has 16 voltage out channels (+/- 10v) and 16 current out channels (0 - 20ma) so I define it in the "Create DAQ Device" dialog as type MIO having 32 AO channels.

If I delete the device from the system definition it will deploy with no errors.

Veristand 2011, Host computer is running Windows 7, RT controller is PXIe-8133.

Has anybody seen this error?

Hi pmac,

That error will occur if you don't select the "Turn off hardware-timed single-point support for analog output" option when configuring the DAQ under your system definition. I've attached a screenshot of this. The reason that you need to check this box is because the 6704 only supports software-timed Analog I/O, as is explained in the manual.

You'll also need to go into output channels 16-31 and manually change the Type of each channel to Current, and the High Level to 0.02 and the low level to 0.00. Once configured correctly, everything should work properly.

Dan,

As you said, checking the box fixed the problem. I was able to add all 32 AO channels and my SDF now deploys with no errors. I'll have to mention, I checked the user manual as well as the spec sheet and I found no mention of hardware/software timed sampling. Can you be more specific about where that info is located?

Thanks for your help

Hi pmac,

I apologize; it doesn't appear to be documented as clearly in the manual as I thought. This KnowledgeBase article does a better job explaining how the 6704 is software timed. Glad to hear you're up and running!
