check if the device is connected

[charlie87]

Hi,

I am developing an application where using cDAQ NI 9174 with modules NI 9401, NI 9205 and NI 9219. I store the last setting including the device channel setting in the xml file and this last setting is loaded when the application starts. I would like to indicate in the TOP VI Front Panel that the cDAQ and the modules are connected. Lets say by LED set to ON. Is there any way how to check if the device is connected programatically ?

Here is how you can check for a connected device.

This is one way to inspect each device:

 

There are a few options under Identification.

Thank you guys. Perfect answers.

There are other options too.  I use the System Configuration palette under Measurement I/O.  It has ways of setting up filters and finding devices that match the filter type.

Hi Mr.Hooovahh, I have been using your CAN library to develop some tools, before all let me congratulate you for your excellent job.
I am using VECTOR CANalyzer hardware along with LabVIEW, I have some problems regarding to the Vector Drivers, from time to time, LV pop up a driver's error window.
I need a solution to verify if the VI detects the drivers, before the main execution.
Could you help me with that?

You are replying to a 9 year old thread that isn't about CAN or Vector.  You should make a new thread with the relevant information.  That being said I would just look to see if there is an error on the error wire, and if there is, to then close any sessions and try reopening them.
