Status of USB-6251 (does it powered)

[VVV]

I have USB-6251. The board is powered by an adapter. Potentially, it could be situation when software is on but the adapter is off. In this case I have tons of error messages. I would like to prevent the end user from starting acquisition in case the adapter is unplugged without showing any error message by just disabling “start” acquisition. Is it possible somehow to get status of USB-6251 without generation of error message? Can you give an example?

Thanks

Hi,

I believe that the section of code below will help you with your application. It queries the devices in the system and then searches for a certain device (for testing I used a USB-6009, you would use USB-6251) returning the location of this device in the array. I then input this into the selector terminal of a case structure and make the -1 case output a false to the “Is device present?” Boolean and also disable and grey out the “Run Button” and the default case output a true and enable the run button. I hope this helps!!
