All,

We are using Allied Vision Mako G-319B cameras with ADVimba. (Firmware 00.01.54.21000, SDK 1.8.0, Driver 1.1.0 ADCore 3.7.0)

An odd behavior we have observed is that rarely image acquisition stops. The PV 'Acquire' reports Acquire but the ArrayCounter_RBV stops incrementing.

We have nine cameras on a dedicated subnet connected to the host. Recently, three cameras stopped acquisition simultaneously ( based on the time-stamp of ArrayData).  I then started the Allied Vision Vimba viewer, and these three cameras are not found. I power cycle the cameras and they now appear in the Vimba viewer.  However, the IOC cannot reestablish image acquisition. For that I have to restart the IOC.

Each camera is connected to a separate IOC on the host (which happens to be a clustered host).

My speculation is that some sort of glitch on the subnet confuses the cameras which then need to be power cycled to recover.  I don't understand why the IOC needs restarting.  If I power cycle a camera which is successfully acquiring, acquisition will stop but I can recover it by pressing 'Stop' followed by 'Start' in the MEDM screen. 

Thoughts?

Not an urgent problem because it happens so rarely.  An annoyance because the camera needs to be power cycled and the IOC restarted.

Regards,
