DAQmxReserveNetworkDevice Long Delay

Solved!
Go to solution

Hi,

 

My C++ application attempts to reserve several cDAQ9184 chassis at start-up using 'DAQmxReserveNetworkDevice'. This appears to work but if a chassis is not connected, or is switched off, the function appears to take several seconds to return an error. Is there another function I can call first to check if the chassis is reachable before I try to reserve it, in the hope that I can speed up my start-up code?

 

Thanks 🙂

Hi Software_Monkey,

 

You may be interested in this post:

Or possibly try to use a self test VI to see if that speeds up the connection.
