reservation problem with DAQmx

[deepearth]

Hi there,

I'm using LV 8.5.1 and a NI USB-6210 Device. In a small app I want to generate two dig. signals, configured in one task. After configuration the task an error occures at "DAQmx Start Task.vi" with error code 50103 Device is reservated, can't go on (translated from used language). On this PC, there's only this USB device in use and only this small app is running.

So my question, how can I find out which app is reservating my device (in LV) and/or can I force to reservate my app for this device?

thx in advance

The app that has the resource reserved is probably your program. Did you create a task in MAX? Are you specifying that as well as using a physical channel control? If you could attach your code, it would help to find the problem.

Hi Dennis,

thanks for your reply. I started to examine my app step by step. Know I know, the error occurs when I set more than one samples per channel in "DAQ MAX Timing (implicit).vi"

I use this app to control startup-conditions on power supplies, just for info.
