waiting get image no feedback

[mzaidi]

Hi..i am using NI 1722 smart camera with VBNI 2009 software.It is used to inspect image for an automative machine.The camera used I/O signal. Recently, vision builder not continous running after waiting get image,hang before acquire image.When this is happend I need to close and reopen the vision builder programme or run in configuration mode.I already change the network cable, camera power cable, and the camera too.It is possible it hang due to I/O signal?Or there are some problem with vision builder programme?

Hi Zaidi,

You might need to check out with your NI-IMAQ driver software as it performs all functions necessary for acquiring and saving images. Try to reinstall NI-IMAQ driver and test it out again. Before using vbai, try to test it using MAX and configure your camera. Check on your IP address too and update software on the smart camera.

Hope this helps.

Warmest Regards,

I have also seen situations where if you are looping as fast as possible on a simple state that just reads a line the target can become unresponsive because it's so busy just polling the line and nothing else. You could try adding a small delay of 2-5ms after you read the line so the application can have a little free time to respond to communication from the host. Newer versions of Vision Builder AI fix this problem I believe. Not sure if you're inspection allows it, but you could also go through the a new End State after reading the line, but this assumes the read line is the first state in your inspection. Going through the end state allows the engine to check for any communication it needs to respond to. We don't check this when looping on the same state over and over I believe.

Hope that works for you.
