Hello,
I am receiving an error message in SignalExpress - "Error -50103 occurred at DAQ Assistant".
There is currently a rotary potentiometer going into AI0 and a Force Sensor into AI1. Everything seems to be working okay until we enable logging.
When we enable logging, we get the error "Error -50103 occurred at DAQ Assistant Possible Reason(s): NI Platform Services: The specified resource is reserved. The operation could not be completed as specified. A possible cause is multiple steps referring to the same device. Verify that each step refers to a different device."
Am I enabling something wrong in the settings? The data/live graph looks great before we hit the record button to log the data - the error just comes on when we try and log data.
Best Regards,
Alex Wishart

Hi,
I noticed that you have configured 2 AI tasks. Let’s try to verify that you are not trying to access equal or different channels from the same device. If so, try to configure the acquisition in just one task.

I have two DAQmx that are aquiring data from different modules at different sample rates etc, its not possible to combine them. I am getting this error. How do I avoid the error?

David-Baratheon,
If you could give some more information or context on you application, I believe it could help narrow down what might be the possible source for your error. What type of DAQmx task types are you using? Which modules? What are your sampling rates and what do you mean by "not possible to combine them"? Are you using the DAQ Assistant as well or using the DAQmz palatte to configure this acquisition. If you could give this information I thinnk its going to go a long way to helping solve your issue.
