Does digital output conflict with impedance analyzer

[sflesh]

I am running one program that produces three digital outputs on DO [0..2] and I am also trying to run the Impedance analyzer at the same time. I get this error message:

Error -200429 occurred at DAQmx Write (Digital 1D Bool 1Chan 1Samp).vi:1

Possible reason(s):

Value passed to the Task/Channels In control is an empty string (or I/O control).

The value must refer to a valid task or valid channels.

I'm not sure what this means, but does it have anything to do with a conflict in hardware when running digital outputs and impedance analyzer?

Any help would be great, I am relatively new at LabVIEW/ELVIS.

Thanks in advance

Shane,

It sounds to be more a referencing issue than an issue between the DIO and impedance analyzer. Sounds like it may not be calling to the correct channel.

Heres some troubleshooting steps:

Can you communicate with the ELVIS board in Measurement and Automation Explorer (MAX)? 

If so, can you use one of our example files to try to do some DIO? 

If that works, try to comment out the impedance analyzer step to make sure it isn't causing the issue. You can comment things out by using the diagram disable structure, which is under programming->structures.
